Chapter 27:   Leg, Ankle, and Foot Injuries

The lower leg, ankle, and foot work as a functional unit. Total body weight above is transmitted to the leg, ankle hinge, and foot in the upright position, and this force is greatly multiplied in locomotion. Thus the ankle and foot are uniquely affected by trauma and static deformities infrequently seen in other areas of the body.


     Injuries of the Leg

The most common injuries in this area are bruises, muscle strains, tendon lesions, postural stress, anterior and posterior compression syndromes, and tibia and fibula fractures. Bruises of the lower leg are less frequent than those of the thigh or knee, but the incidence of intrinsic strain, sprain, and stress fractures are much greater.

A continual program of running and jogging is typical of most sports. The result is often strengthening of the antigravity muscles at the expense of the gravity muscles — producing a dynamic imbalance unless both gravity and antigravity muscles are developed simultaneously. An anatomic or physiologic short leg as little as an eighth of an inch can affect a stride and produce an overstrain in long-distance track events.

Bruises and Contusions

The most common bruise of the lower extremity is that of the shin where disability may be great as the poorly protected tibial periosteum is usually involved. Skin splits in this area can be most difficult to heal. Signs of suppuration indicate referral to guard against periostitis and osteomyelitis.

Management.   Treat as any skin-bone bruise with cold packs and antibacterial procedures, and shield the area with padding during competitive activity. When long socks are worn, the incidence of shinbone injuries is reduced. An old but effective protective method in professional football that does not add weight is to place four or five sheets of slick magazine pages around the shin that are secured by a cotton sock which is covered by the conventional sock. A blow to the shin is reduced to about a third of its force as the paper slips laterally on impact.

      GASTROCNEMIUS CONTUSION

This is a common and most debilitating injury in contact sports. It is characterized by severe calf tenderness, abnormal muscle firmness of the engorged muscle, and inability to raise the heel during weight bearing.

Management.   Treat with cold packs, compression, and elevation for 24 hr. Follow with mild heat and contrast baths. Massage is contraindicated as it might disturb muscle repair. The danger of ossification is less in the calf than in the thigh, but management must incorporate precautions against adhesions.

      TRAUMATIC PHLEBITIS

Contusion to the greater saphenous vein may lead to rupture resulting in extensive swelling, ecchymosis, redness and other signs of local phlebitis. Tenderness will be found along the course of the vascular channel. During treatment, referral should be made upon the first signs of thrombosis.

Management.   Management is by rest, cold, compression, and elevation for at least 24 hr. Later, progressive ambulation, mild heat, and contrast baths should be utilized. Progressive exercises may begin in 4-6 days. When competitive activity is resumed, the area should be provided extra protection.

Chapter 22:   Shoulder Girdle Injuries

This chapter concerns injuries of and about the scapula, clavicle, and shoulder. In sports, the shoulder girdle is a common site of minor injury and a not infrequent site of serious disability. It is second only to the knee as a chronic site of prolonged disability. Upper limb injuries amount to about 20% of sport-related injuries. They can be highly debilitating, require considerable lost field time, and can easily ruin a promising sports career.


     Introduction

The versatile shoulder girdle consists of the sternoclavicular, acromioclavicular, and glenohumeral joints, and the scapulothoracic articulation. These allow, as a whole, universal mobility by way of a shallow glenoid fossa, the joint capsule, and the suspension muscles and ligaments. The shoulder, a ball-and-socket joint, is freely movable and lacks a close connection between its articular surfaces.

The regional anatomy offers little to resist violent shoulder depression, and the shoulder tip itself has little protection from trauma. The length of the arm presents a long lever with a large head within a relatively small joint. This allows a great range of motion with little stability. The stability of the shoulder is derived entirely from its surrounding soft tissues.

History and Initial Care

A careful history recording the mechanism of trauma and the position of the limb during injury, careful inspection and palpation of the entire region, muscle and range-of-motion tests, and other standard neurologic-orthopedic tests will often arrive at an accurate diagnosis without the necessity of x-ray exposure. Forceful manipulations should always be reserved for late in the examination to evaluate contraindications.

Contusions, strains, sprains, bursitis, and neurologic deficits must be alertly recognized and treated. Fractures and dislocations, obviously, take precedence over soft-tissue injuries with the exception of severe bleeding. Always check for bony crepitus, fracture line tenderness and swelling, angulation and deformity. Because the shoulder readily “freezes” after injury, treatment must strive to maintain motion as soon as possible without encouraging recurring problems. The key to avoiding prolonged disability is early recognition and early mobilization.

Chapter 15: Bone and Joint Injuries

In traditional general medical practice, the musculoskeletal system is the most overlooked system in the body, yet it comprises over half the body mass. The relationship between structure and function, and the interrelationship between all body systems, cannot be denied. Muscles, bones, and connective tissues are involved in both local and systemic pathology, and in a wide assortment of functional and referred disturbances. Thus, great care must be taken in eliciting the details of a complaint when any musculoskeletal disorder is suspected. This section reviews the basis of alert management of bone and joint injuries within the health care of athletic and recreational injuries.


     Bone Injuries

Correlation of the history of the present complaint with musculoskeletal dysfunction must be done in detail and with care. Maintain accurate initial and progress records with repeated monitoring. Few patients can appreciate the relationship of dysfunction in one somatic part with a distant somatic part, let alone the relationship between a somatic dysfunction and a visceral dysfunction.

Background

Musculoskeletal symptoms may be the first clues toward poor structural adaptation or stress adaptation. The most common musculoskeletal symptoms are joint stiffness, joint swelling, and joint pain. Bones, being essentially nonyielding structures, are damaged when excessive force is applied directly or indirectly. The nature of the damage depends on the direction of the applied force on the bones and the manner in which these bones are attached to other structures. The principal acute skeletal injuries are sprains, strains, subluxations, fractures, and dislocations.

Normal bone has an excellent blood supply with some exception in the metaphyseal area; but tendons, ligaments, discs, and cartilage are poorly vascularized. Yet both bone and joints challenge the host’s defensive mechanisms. The pressure of pus under hard bone blocks circulation, and emboli and thrombosis can cause additional devascularization. When circulation is deficient, local phagocytic function and nutrition are deficient, and cure is stymied.

The most accurate diagnosis can be made immediately after injury, before swelling clouds the picture. Many fracture and dislocation complications such as nerve and vessel injury occur not from the trauma itself but from poor first aid which does not provide adequate splinting prior to movement. Traumatic bone injury rarely occurs without significant soft-tissue damage. The physical examination must be gentle but thorough because soft-tissue trauma is poorly visible on roentgenograms for several days after injury. For example, a working diagnosis of stress fracture may have to be made in the absence of classic symptoms by bony tenderness alone as the fracture may not be demonstrable on x-ray films for 10-14 days or longer.

Probing the History

Symptoms of a musculoskeletal nature that cannot be linked to trauma are suspect of a chronic organic process. Unfortunately, a history of stress or strain may not be remembered. Even severe trauma is easily put out of the mind uring a game when emotions are high or forgotten once the pain and swelling have left. Whether pain is present or not, the history must be probed to determine if the dysfunction is the result of bone, the joint, or the motor apparatus involved in the joint motion.

Chapter 8: Clinical Disorders and the Sensory System

This chapter describes those sensory mechanisms, joint signals, and abnormal sensations (eg, pain, thermal abnormalities) that have particular significance within clinical diagnosis. The basis and differentiation of pain are described, as are the related subjects of trigger points and paresthesia. The chapter concludes with a description of the neurologic basis for the evaluation of the sensory system and the sensory fibers of the cranial nerves.


     THE ANALYSIS OF PAIN IN THE CLINICAL SETTING

Although all pain does not have organic causes, there is no such thing as “imagined” pain. Pain that can be purely isolated as a structural, functional, or an emotional effect is rare. More likely, all three are superimposed upon and interlaced with each other in various degrees of status. This is also true for neural, vascular, lymphatic, and hormonal mechanisms.

Common Causes of Pain and Paresthesia

The common causes of pain and paresthesia are:

(1) obvious direct trauma or injury;

(2) reflex origins in musculoskeletal lesions, which deep pressure often exaggerates, such as trigger areas;

(3) peripheral nerve injury (eg, causalgia), which results in an intense burning superficial pain;

(4) the presence of nerve inflammations and degeneration of the peripheral or CNS, which frequently cause other changes indicative of such lesions;

Chapter 4: The Horizontal Neurologic Levels
and Related Clinical Concerns


This chapter describes the basic functional anatomy and clinical considerations of the horizontal aspects of the supratentorial, posterior fossa, spinal, and peripheral levels of the nervous system.


     OVERVIEW

The reader should keep in mind that the various aspects of the nervous system as described in this manual (eg, longitudinal and horizontal systems) are only reference guides that are visualizations of a patient’s nervous system in the upright position. They can be likened to the lines of longitude and latitude on a globe of the earth.

Such systems do not exist physically, but they do serve as excellent mental grid-like tools (viewpoints) during localization and areas in which and from which relationships can be described. For example, although the longitudinal systems take a general vertical course within the spinal column there are numerous alterations and they actually become horizontal when decussating. While the horizontal levels are spatially placed in and extend from the CNS in a general segmental manner, they soon take a widely diffuse course as they project toward their destinations. Thus, references to longitudinal and horizontal levels are just general viewpoints.

It is helpful for study purposes to isolate the body into certain systems, as described above, organize systems into organs, organs into tissues, tissues into cells, and cells into their components. However, we should keep in mind that, physically and functionally, there is only one integrated body and it is more than the sum of its parts. And even the body cannot be thought of as truly separate from its external environment. Although we may do this for study purposes, it is a limited viewpoint.

Chapter 3: The Longitudinal Neurologic Systems

This chapter succinctly describes the basic structure and function of the six major longitudinal systems; viz, the sensory, motor, visceral, vascular, consciousness, and cerebrospinal fluid systems.

As we begin this chapter, it might be well for the reader to subjectively grasp the significance of the motor and sensory systems as far as possible. One exercise in this is to imagine that you had become unconscious and someone has placed you in a remote dark empty cellar, far beyond any source of environmental sound. The first thing you realize is that you are a total sensory and motor paralytic from the neck caudad. You are unable to move even a fingertip because your motor system is not functioning. Because there is no feeling, you do not know whether you are recumbent or tied in a chair. Your vision is normal, but there is no light. Your hearing is normal, but there is no sound. Your taste buds are functional, but there is nothing to eat or drink. Your olfactory organs are functional, but there are no detectable odors. There is little left except thought and memory.

After a time in this predicament, thoughts undoubtedly arise such as, “I wish I had really looked at the beauty of the world when I had a chance. I wish I had listened to the music of the masters and even the birds in my backyard when I had a chance. I gulped down so many delicious meals. I had a beautiful garden, but I rarely took time to appreciate its design and fragrance. I even failed to take time to appreciate the texture of my own clothes. I was in such a hurry to go nowhere that was more important. I missed so much.”


     OVERVIEW

The human nervous system is a marvel in organizing and adapting to internal and external environmental changes:

(1) The receptors and afferent neurons of the visceral and somatic input systems are necessary to detect internal and external environmental changes.

(2) The visceral efferent neurons and the muscles of the motor output system must be stimulated if action is to be taken.

(3) The integrative system serves as intermediary stations via a complex arrangement of interneurons whose synapses control impulse strength and signal direction from the sensory system to the motor system.

Chapter 1: Introduction to Sports-related Health Care

If you were to ask the average coach about the responsibilities of an athlete, he would most likely reply that he or she was to conduct one’s self to the credit of the team, play fair, obey the officials, keep in training, be a credit to the sport, follow the rules, and enjoy the game: win or lose. This is the rhetoric commonly spooned to the naively inclined. If it were true, fewer sports injuries would be suffered.

With rare exception, even the Little Leaguer is commonly taught to WIN, drilled to disguise foul play from the eyes of the referees and umpires. Even in so-called noncontact sports, emphasis is often placed on getting the other team’s stars out of the game without causing injury to your own team. While conditioning is emphasized, the motivation is frequently on the preservation of a potential winning season rather than on prevention of a personal injury to a human being.

These words are harsh, but realistic. Yet, doctors handling athletic injuries must have a realistic appraisal of sports today if they are in good conscience to properly evaluate disability and offer professional counsel.


     The Art of Evaluation

All people participating in vigorous sports should have a complete examination at the beginning of the season; and re-evaluation is often necessary at seasonal intervals. Re-evaluation is always necessary with cases where the candidate has suffered a severe injury, illness, or had surgery.

Evaluation begins with questioning. Because of drilled routine, any doctor is well schooled in the taking of a proper case history. But with an athletic injury, both obvious and subtle questions often appear. How extensive was the preseason conditioning? How much time for warm up is allowed before each game or event? What precautions are taken for heat exhaustion, heat stroke, concussion, and so forth? Does the coach make substitution immediately upon the first sign of disability for proper evaluation? How adequate is the protective gear? How many others on the team have suffered this particular injury this season?

Who, what, when, where, how, and WHY? These are the questions which must be answered before any positive course of health care can be extended. A detailed history of past illness and injury is vital. In organized sports, an outline of the regimen of training should be a part of the history, as well as a record of performance. Most sports will require a detailed locomotor evaluation of the player. Special care must be made in evaluating the preadolescent competitor because of the wide range of height, weight, conditioning, and stages of maturation. A defect may bar a candidate from one sport but not another, or it may be only a deterrent until it is corrected or compensated. Many famous athletes have become great in spite of a severe handicap.

Chapter 4: The Language of the Health-Care Professions

When more than one person is involved in any task, good communication is basic for success. Thus, a sound foundation in chiropractic terminology is an important functional skill to be possessed by any chiropractic assistant. It is a requisite to becoming an important asset to the office.

If a CA’s duties include taking dictation of case histories, examination findings, or narrative reports, she must know how to record scientific terms in shorthand and know how to spell them accurately. A good medical dictionary will be an important reference. Even if dictation is not required, she still must know what the doctor means when certain terms are used. He will expect his assistants to have a fundamental grasp of commonly used medical terms, abbreviations, and acronyms.

Do not enter this study lightly. On the other hand, do not let yourself be appalled by the formidable and specialized vocabulary used in health care. The learning of professional terms will not come overnight. It will extend the entire length of your career as new and unfamiliar words are confronted.


     THE UNIVERSAL LANGUAGE OF HEALTH CARE:
     WHY IT IS NECESSARY


It would not be unusual if you found many words used in the first three chapters of this program strange or at least unknown. When you undertake the transposition from lay person to chiropractic assistant, you are faced with an entirely new language that must be mastered so the transition be successful. The most efficient method to accomplish this is by securing an understanding of basic word roots, prefixes, and suffixes used in the formation of technical words and gaining an understanding of the meaning of commonly used abbreviations and acronyms. Study and repetitive use is the way to mastery.

A fundamental knowledge of anatomy (structure) and physiology (function) will be of great assistance in learning terminology. A basic understanding of human anatomy and physiology is offered in the following chapter. This chapter will prepare you for the terminology of those and other clinical subjects. While professional terms may at first seem strange, you will see their purpose in this and following chapters.

Chapter 2:   Mechanical Concepts and Terms

All motor activities such as walking, running, jumping, squatting, pushing, pulling, lifting, and throwing are examples of dynamic musculoskeletal mechanics. To better appreciate the sometimes simple and often complex factors involved, this chapter reviews the basic concepts and terms involved in maintaining static equilibrium. Static equilibrium is the starting point for all dynamic activities.


     Energy and Mass

Biomechanics is constantly concerned with a quantity of matter (whatever occupies space, a mass) to which a force has been applied. Such a mass is often the body as a whole, a part of the body such as a limb or segment, or an object such as a load to be lifted or an exercise weight. By the same token, the word “body” refers to any mass; ie, the human body, a body part, or any object.


Energy

Energy is the power to work or to act. Body energy is that force which enables it to overcome resistance to motion, to produce a physical effect, and to accomplish work. The body’s kinetic energy, the energy level of the body due to its motion, is reflected solely in its velocity, and its potential energy is reflected solely in its position. Mathematically, kinetic energy is half the mass times the square of the velocity: m/2 X V524. In a closed system where there are no external forces being applied, the law of conservation of mechanical energy states that the sum of kinetic energy and potential energy is equal to a constant for that system.

Potential energy (PE), measured in newton meters or joules, is also stored in the body as a result of tissue displacement or deformation, like a wound spring or a stretched bowstring or tendon. It is expressed mathematically in the equation PE = mass X gravitational acceleration X height of the mass relative to a chosen reference level (eg, the earth’s surface). Thus, a 100-lb upper body balanced on L5 of a 6-ft person has a potential energy of about 300 ft-lb relative the ground.


The Center of Mass

The exact center of an object’s mass is sometimes referred to as the object’s center of gravity. When an object’s mass is evenly distributed throughout, the center of mass is located at the object’s geometric center. In the human body, however, this is infrequently true, and the center of mass is located towards the heavier, often larger, aspect. When considering the body as a whole, the center of mass in the anatomic position, for instance, is constantly shifted during activity when weight is shifted from one area to another during locomotion or when weight is added to or subtracted from the body.

The term weight is not synonymous with the word mass. Body weight refers to the pull of gravity on body mass. Mass is the quotient obtained by dividing the weight of a body by the acceleration due to gravity (32 ft/sec524). Each of these terms has a different unit of measurement. Weight is measured in pounds or kilograms, while mass is measured by a body’s weight divided by the gravitational constant. The potential energy of gravity can be simply visualized as an invisible spring attached between the body’s center of mass and the center of the earth. The pull is always straight downward so that more work is required to move the body upward than horizontally (Fig. 2.1).

Chapter 6:   General Spinal Biomechanics

This chapter discusses the vertebral column as a whole and serves as a foundation for the following three chapters that consider the regional aspects of the spine and pelvis. Emphasis here is on gross structure, function, spinal kinematics, and other general biomechanical implications.


     Background

The vertebral column is a mechanical marvel in that it must afford both rigidity and flexibility.

The Spine as a Whole

The segmental design of the vetebral column allows adequate motion among the head, trunk, and pelvis; affords protection of the spinal cord; transfers weight forces and bending moments of the upper body to the pelvis; offers a shockabsorbing apparatus; and serves as a pivot for the head. Without stabilization from the spine, the head and upper limbs could not move evenly, smoothly, or support the loads imposed upon them (Fig. 6.1).

Essentially because of its various adult curvatures, the bony spine is anatomically divided into the seven cervical vertebrae, the twelve thoracic vertebrae, the five lumbar vertebrae, and the ossified five sacral and four coccygeal segments. From C1 to S1, the articulating parts of these vertebrae are the vertebral bodies, which are separated by intervertebral discs (IVD’s), and the posterior facet joints. The IVD’s tend to be static weight-bearing joints, while the facets function as dynamic sliding and gliding joints.

      WEIGHT DISTRIBUTION

The flexible vertebral column is balanced upon its base, the sacrum. In the erect position, weight is transferred across the sacroiliac joints to the ilia, then to the hips, and then to the lower extremities. In the sitting position, weight is transferred from the sacroiliac joints to the ilia, and then to the ischial tuberosities.

      SPINAL LENGTH

About 75% of spinal length is contributed by the vertebral bodies, while 25% of its length is composed of disc material. The contribution by the discs, however, is not spread evenly throughout the spine. About 20% of cervical and thoracic length is from disc height, while approximately 30% of lumbar length is from disc height. In all regions, the contribution by the discs diminishes with age.


Development of the Spine

In brief, development occurs in three stages: mesenchymal, chondrification, and ossification.

MESENCHYMAL AND CHONDRIFICATION ORIGINS

Just prior to the 4th week of embryonic development, a vertebral segment begins to develop as paired condensations of mesenchyme (somites) around the longitudinal notochord and dorsal neural tube. One or usually two chondrification centers appear (6 weeks) in the centrum and begin to form a cartilaginous model surrounded by anterior and posterior longitudinal ligaments which are complete by 7-8 weeks. Chondrification centers also form in the neural arches and costal processes. A thick ring of nonchrondrous cells establishes the model IVD around the longitudinal string of beaded notochordal segments (Fig. 6.2).

Chapter 10: Introduction to Chiropractic Physiologic Therapeutics

The use of physiotherapy and physical therapy to enhance the effects of the chiropractic adjustment in treatment can be significant in many cases. Superficial heat, diathermy, cold, microwaves, ultrasound, ultraviolet rays, galvanic and sinusoidal currents, traction, hydrotherapy, or therapeutic massage and exercise are among the therapies that may benefit the patient when properly applied. These procedures may help to reduce stiffness in joints, relieve tension, relax muscle spasm, and offer many other physiologic benefits.

Special precautions, however, must be observed when treating patients of advanced age. Special consideration must also be given to indications and contraindications, patient sensitivity, intensity, and duration of treatment.

Special caution must be used with patients that have heart and blood pressure problems, renal failure, diminished sensation or circulation, or an inability to tolerate heat or cold. For example, patients with Raynaud’s disease do not tolerate cold. Patients with other circulatory problems do not tolerate thermotherapy because they have less ability to dissipate the heat. Patients with a distinct loss of sensation will not realize if an area is being overheated or even being burned.

A patient’s tolerance cannot be the only guide to intensities and duration of treatment. Frequent checking, both visually for redness and by palpation to determine over heating, must be done during the treatment period. Reasonable examination, monitoring, and care by the doctor can avoid problems in most instances.


INTRODUCTION

Physiotherapy techniques are frequently used preparatory to the chiropractic adjustment to improve function, relieve spasm, minimize pain, and enhance circulation and drainage. They are often used before primary care to relax the patient and condition tissues, and posttherapy to relive pain and prevent deformities resulting from trauma or disease and to maintain what has been gained in treatment. There are also times when it may be considered primary therapy. Rehabilitation objectives are shown in Table 10.1.

A QUIZ: Identifying Common and Dangerous Neck Masses

A QUIZ: Identifying Common and Dangerous Neck Masses

The Chiro.Org Blog


Accurate diagnosis of neck masses is critical to minimize morbidity and mortality. However, differentials vary greatly and can be challenging for the physician.

Neck masses are common presenting complaints, but differential diagnoses vary considerably based on patient age and the location of the neck mass. Most neck masses in the pediatric population have an infectious etiology, whereas an adult neck mass is considered to be a malignancy until proven otherwise. Evaluation of a neck mass depends on the history and physical examination; evaluation may also include observation, antibiotics, fine-needle aspiration, open biopsy, neck dissection, or wide local excision.

Clinical Decision-making to Facilitate Appropriate Patient Management in Chiropractic Practice: ‘The 3-questions Model’

Clinical Decision-making to Facilitate Appropriate Patient Management in Chiropractic Practice: ‘The 3-questions Model’

Background:   A definitive diagnosis in chiropractic clinical practice is frequently elusive, yet decisions around management are still necessary. Often, a clinical impression is made after the exclusion of serious illness or injury, and care provided within the context of diagnostic uncertainty. Rather than focussing on labelling the condition, the clinician may choose to develop a defendable management plan since the response to treatment often clarifies the diagnosis.

Discussion:   This paper explores the concept and elements of defensive problem-solving practice, with a view to developing a model of agile, pragmatic decision-making amenable to real-world application. A theoretical framework that reflects the elements of this approach will be offered in order to validate the potential of a so called ’3-Questions Model’;

Summary:   Clinical decision-making is considered to be a key characteristic of any modern healthcare practitioner. It is, thus, prudent for chiropractors to re-visit the concept of defensible practice with a view to facilitate capable clinical decision-making and competent patient examination skills. In turn, the perception of competence and trustworthiness of chiropractors within the wider healthcare community helps integration of chiropractic services into broader healthcare settings.


From the FULL TEXT Article:

Development of the 3-questions Model

The chiropractic profession, particularly in Western countries, finds itself in a rapidly evolving healthcare landscape, with ‘modernisation’ being a consequence of escalating costs, an aging population, and an ever-diminishing relative resource base [9]. With a view to rationalising resources health system decision-makers are increasingly vigilant about the delivery of safe, evidence-based, cost-effective care, summarised as “the right care at the right time in the right place” [10, 11]. With this imperative in mind, the authors propose three straightforward questions that frame clinical decision-making within the context of diagnostic uncertainty.

The Facts About Fevers

The Facts About Fevers

The Chiro.Org Blog


To Your Health ~ January 2012

By Claudia Anrig, DC


Our body’s first line of defense when invaded by any microbe, virus or bacteria is cells called microphages; a strong, healthy immune system may be able to eliminate the problem with this first step alone. If these fail to contain the microbe/”bug,” then the body creates other pryogens and proteins to try to assist. Once these have been created, the hypothalamus in the brain recognizes there is an invader and raises the body temperature to assist in killing it off.

This elevated temperature will generally be just a couple of degrees, but the hypothalamus determines, based on the number of pryogens and proteins, what will be necessary to eliminate the microbe/bug. If the hypothalamus creates additional biochemicals to try to protect the body, then the temperature rises accordingly.

Defining a Fever

For all children above the age of 3 months, a fever is actually a good thing. It’s a sign that their immune system is functioning properly. Although many parents will panic when their child has a temperature above 98.6° F (37° C), and this is understandable since many health care providers have called this a “low-grade fever,” the reality is that children’s temperature may naturally run a little higher than what many consider the norm.

A true low-grade fever is anything between 100°F and 102.2°F (37.8° C and 39° C). This level of fever is beneficial; with most microbes/”bugs” that a child will be exposed to, this fever will assist the body in repelling the invader.

A moderate-grade fever is typically between 102.2° F and 104.5° F (39° C and 40° C). This temperature is still considered beneficial; if a child’s body has reached this temperature, it’s what’s needed to kill whatever bacteria or virus their body is attempting to fight.

A high fever is a fever greater than 104.5° F (40° C). This fever may cause the child some discomfort and result in a bit of crankiness. Generally indicative of a bacterial infection, this fever means that the body is fighting something a little more serious than the common cold. While it will not cause brain damage or any other harm to a child, it is wise to seek assistance from their medical provider.

A serious fever is one that is at or above 108° F (42° C); this fever can be harmful.

Can a Fever Be Dangerous?

CHAPTER 4:   CERVICAL SPINE TRAUMA

The cervical spine provides musculoskeletal stability and supports for the cranium, and a flexible and protective column for movement, balance adaptation, and housing of the spinal cord and vertebral artery. It also allows for directional orientation of the eyes and ears. Nowhere in the spine is the relationship between the osseous structures and the surrounding neurologic and vascular beds as intimate or subject to disturbance as it is in the cervical region.

BACKGROUND

Whether induced by trauma or not, cervical subluxation syndromes may be reflected in total body habitus. IVF insults and the effects of articular fixations can manifest throughout the motor, sensory, and autonomic nervous systems. Many peripheral nerve symptoms in the shoulder, arm, and hand will find their origin in the cervical spine, as may numerous brainstem disorders.


COMMON INJURIES AND DISORDERS OF THE CERVICAL SPINE

Cervical spine injuries can be classified as

(1) mild (eg, contusions, strains);

(2) moderate (eg, subluxations, sprains, occult fractures, nerve contusions, neurapraxias);

(3) severe (eg, axonotmesis, dislocation, stable fracture without neurologic deficit); and

(4) dangerous (eg, unstable fracture-dislocation, spinal cord or nerve root injury).

Spasm of the sternocleidomastoideus and trapezius can be due to strain or irritation of the sensory fibers of the spinal accessory nerve as they exit with the C2—C4 spinal nerves. The C1 and C2 nerves are especially vulnerable because they do not have the protection of an IVF. Radicular symptoms are rarely evident unless an IVD protrusion or herniation is present.

PREVALENCE

Because of its great mobility and relatively small structures, the cervical spine is the most frequent site of severe spinal nerve injury and subluxations. A large variety of cervical contusions, Grade 1—3 strains and sprains, subluxations, disc syndromes, dislocations, and fractures will be seen as the result of trauma.

The most vulnerable segments to injury are the axis and C5—C6 according to accident statistics. Surprisingly, the atlas is the least involved of all cervical vertebrae. In terms of segmental structure, the vertebral arch (50%), vertebral body (30%), and IVD (30%) are most commonly involved in severe cervical trauma. While the anterior ligaments are only involved in 2% of injuries, the posterior ligaments are involved in 16% of injuries.

EMERGENCY CARE

In the emergency-care situation, the patient with spinal cord injury must be treated as if the spinal column were fractured, even when there is no external evidence. Immediate and obvious symptom of spinal cord injury parallel those of fractures of the spinal column. The establishment of an adequate airway takes priority over all other concerns except for spurting hemorrhage.

Brain Impact: Concussions, Chiropractic and New Laws

Brain Impact: Concussions, Chiropractic and New Laws

The Chiro.Org Blog


SOURCE: Dynamic Chiropractic

By Robert “Skip” George, DC, CCSP, CSCS


Concussions are (finally) getting the attention of the athletic world, state governments and health care providers of all disciplines.

On Oct. 23, 2011, San Diego Chargers offensive guard Kris Dielman suffered a concussion during a football game against the New York Jets with 12:31 left to play.

He landed hard on the ground after a wicked collision with a Jets linebacker, then got up, wobbled and went back to playing the rest of the game, taking several more hits to the head. Neither the Chargers training staff nor the NFL referees recognized how serious his head injury was as he “waved off” his sideline training staff to return to the huddle. On the flight home to San Diego after the game, Dielman suffered a “grand mal” seizure and will most likely not play for the rest of the season.

Magnitude of the Problem

Concussions are getting much-needed attention in the press, especially given the short- and long-term cognitive loss, early-onset dementia, physical disability and even death resulting from traumatic brain injury (TBI). Chronic traumatic encephalopathy is a chronic, degenerative neurologic disease linked to repetitive head trauma and is known as an invisible killer that can make a 35-year-old brain look more like 80 years old.

There are 250,000 concussions annually in football alone. The prevalence in high-school and college athletics is a major concern, especially considering how big, fast and strong high-school and college athletes have become, and how their play emulates the professionals. This “evolution” is exacting a terrible toll regarding TBI in not only football, but also soccer, hockey, wrestling, water polo and cheerleading.

 

Three Purdue University professors tracked 21 football players from Lafayette Jefferson High School in Indiana. For two years they kept a record of every hit in practice and during games. They found that half of the players had neurophysiologic changes from contact. They also discovered that the repetitive hits the players were receiving had a cumulative effect on the brain and resulted in brain wave changes that mimicked concussion, even when the contact did not result in a concussion!

Concussion Basics

What is a concussion? It can be defined as “a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces” or “an immediate and transient loss of neuronal function secondary to trauma.” Signs and symptoms include but are not limited to thinking deficits, lack of sustained attention; amnesia; confused mental status; dazed look / vacant stare; slurred or incoherent speech; vomiting; nausea; emotional liability; slow motor or verbal response; memory deficits; poor coordination; dizziness; headache; restlessness; nervous weakness; exhaustion; and irritability.

Chapter 15:   Chiropractic Perspectives On Myofascial Therapy

The purpose of this chapter is to improve the doctor of chiropractic’s understanding of the significance of myofascial pain and dysfunction, and to improve the chiropractor’s level of competence in diagnosing the myofascial component of the subluxation complex.

The myofascial orientation in the chiropractic setting directs the doctor to look first for a myofascial source of the patient’s pain, and when found, to use numerous techniques and procedures to offer rapid relief. Lowe recommends broad spectrum therapeutics to be employed after the performance of myofascial therapy to assure maximum flexibility. [1]

Definition

Myofascial therapy may be defined in several ways. Basically, it is the treatment of the myopathophysiologic component of the vertebral subluxation complex. It is also the treatment of trigger points, areas of increased neurologic activity in muscle tissue, causing the secondary referral of pain with subsequent associated autonomic changes. [2]

The pain attributed to myofascial dysfunction is usually restricted to a certain region such as the cervical or upper thoracic area, lumbar and buttock area, or the cranial/TMJ area. A trigger point, often the cause of such pain, is always tender and palpably taut. This prevents full lengthening of the muscle and produces muscle weakening, altered proprioception, predictable referred pain patterns, and an objectively verifiable local twitch response during palpation. [3]

Historic Background

Several key figures have contributed to our understanding of the widespread cause of muscular pain syndromes, among them Travell, Rolf, and, in our own profession, Nimmo. Another chiropractor who added greatly to our understanding of the role of muscles in various pain syndromes was Gillet of Belgium. Gillet wrote, “Concerning the subluxation or misalignment, we prefer the term fixation, which describes far more accurately the actual status of the [peri]articular soft tissues, where we will find that it is the state of these tissues that actually keeps the two surfaces from moving. The osteopaths, very early on, stated that the soft tissues can vary from the simplest muscular contracture to a complete degenerative fibrosis of the muscles. The previous facts are not new ….unfortunately, x-rays, introduced early in chiropractic history, have done much to propagate the idea of the spine as a string of bones. Even today, many practitioners act as if they still believe the childish propaganda they so nimbly offer to the public, that it’s a bone out of place in the back.” [4]

Chapter 6:   Motion Palpation of the Pelvis

     Differentiating Sacroiliac from Lumbar Fixations

To differentiate sacroiliac from lumbar fixations, Faye offers the following comments for consideration.

With the patient sitting and their hands placed behind their head, rotate the patient’s trunk first to the right and then to the left. Special care should be taken not to lift the patient’s pelvis. Motion restriction of the patient’s left lumbar facets or left sacroiliac joint will reduce rotation to the left (positive theta Y). Motion restriction of the patient’s right lumbar facets or right sacroiliac joint will inhibit rotation of the patient’s trunk to the right (negative theta Y).

To discern between a lumbosacral or sacroiliac lesion, the patient is allowed to relax against the doctor (patient’s hands are still behind their head). In this position, the lumbosacral joint is relatively stress free. Next, twist the patient’s trunk into posterior rotation on the right until the patient’s left ischial tuberosity lifts slightly (buttocks remaining on palpation stool). In this position, there is a marked posterior torsion strain on the right sacroiliac joint. If pain arises in the right sacroiliac that can be relieved by pushing the left ilium posteriorly, then the pain can be assumed to arise from the right sacroiliac joint. Reverse the doctor-patient positions to differentiate fixations on the left. This is Mennell’s modified Kemp’s test for the lumbosacral area.

Here are some helpful clues: The patient suffering from sacroiliac dysfunction gets up in the morning with stiffness that improves with activity. The patient suffering with facet inflammation and/or an IVD lesion arises improved, but the condition worsens as the day goes on. Fixation produces a sharp pain on certain movements that is relieved when the site is not stressed. Other points characteristic of a sacroiliac lesion are:

1.   There is usually unilateral pain in the sacroiliac joint.

2.   The patient may describe an onset involving a lifting or twisting maneuver upon which a “catch” in the back is felt.

3.   The patient has difficulty rising from bed, and the disability is worse in the morning, improving with activity.

Chapter 5:   The Lumbar Spine

This chapter describes the dynamic chiropractic approach to the correction of fixations of the lumbar spine and related tissues. Emphasis is on biomechanical, fixation, and therapeutic considerations. Some significant points in differential diagnosis are also described.

According to Faye, the three most common types of low back pain are:

(1) the lumbar facet syndrome,

(2) the sacroiliac syndrome, and

(3) the lumbar radicular syndrome, which may be discogenic or biomechanical in origin.

Each of these types can be acute or chronic, traumatic or nontraumatic, and have varying degrees of concomitant pathomechanics. The syndromes are named according to the level of inflammation or pain-producing structures and more than likely not the area in need of adjustments. Their typical cause may be due to:

sprain/strain,
overuse,
poor posture,
disuse,
joint dysfunction (fixation/hypermobility),
development abnormality,
degenerative changes,
or various combinations of these origins.

In addition, the possibility of viscerosomatic and somatosomatic reflexes should not be overlooked.

Chapter 26:   LUMBAR SPINE, PELVIC, AND HIP INJURIES

Facet Syndromes

The subluxation of lumbar facet structures, states Howe, is a part of all lumbar dyskinesias and must be present if a motor unit is deranged. In a three-point articular arrangement, such as at each vertebral motor unit, no disrelationship can exist that does not derange two of the three articulations. Thus, determination of the integrity or subluxation of the facets in any given motor unit is important in assessing that unit’s status.

     ROENTGENOLOGIC CONSIDERATIONS

Any method of spinographic interpretation which utilizes millimetric measurements from any set of preselected points is most likely to be faulty because structural asymmetry and minor anomaly is universal in all vertebrae. However, the estimation of the integrity of facet joints is a reliable method of assessing the presence of intervertebral subluxation. An evaluation of the alignment of the articular processes comprising a facet joint may be difficult from the A-P or P-A view alone when the plane of the facet facing is other than sagittal or semisaggital. In this case, oblique views of the lumbosacral area are of great value in determining facet alignment since the joint plane and articular surfaces can nearly always be visualized.

When one cannot visually identify disrelationships of the facet articular structures, Howe suggests use of Hadley’s S curve. This is made by tracing a line along the undersurface of the transverse process at the superior and bringing it down the inferior articular surface. This line is joined by a line drawn upward from the base of the superior articular process of the inferior vertebrae of the lower edge of its articular surface. These lines should join to form a smooth S. If the S is broken, subluxation is present. This A-P procedure can be used on an oblique view.

     DIFFERENTIATION

To help differentiate the low back and sciatic neuralgia of a facet syndrome to that of a disc that is protruding:

l.   With the patient standing with feet moderately apart, the doctor from behind the patient firmly wraps his arms around the patient’s pelvis and firms his lateral thigh against the back of the patients’ pelvis. The patient is asked to bend forward. If it is a facet involvement, the patient will feel relief. If it is a disc that is stressed, symptoms will be aggravated.

2.   In facet involvement, the patient seeks to find relief by sitting with feet elevated and resting upon a stool, chair, or desk. In disc involvement, the patient keeps knees flexed and sits sideways in his chair and moves first to one side and then to the other for relief. If lumbosacral and sacroiliac pain migrates from one to the other side, it is suspected to be associated with arthritic changes.

Lumbosacral Instability

Lumbosacral instability is a mechanical aberration of the spine which renders it more susceptible to fatigue and/or subsequent trauma by reason of the variance from the optimal structural weight-bearing capabilities. Hariman states that between 50% and 80% of the general population exhibit some degree of the factors which predispose to instability whether by reason of anomalous development of articular relationships or altered relationships due to trauma or disease consequences. It is the most common finding of lumbosacral roentgenography and often brought to light after an athletic strain.

Chapter 22:   NECK AND CERVICAL SPINE INJURIES

Soft-Tissue Injuries of the Posterior Neck

     Cervical Contusions, Strains, and Sprains

Contusions in the neck are similar to those of other areas. They often occur to the cervical muscles or spinous processes. Painful bruising and tender swelling will be found without difficulty, especially if the neck is flexed. Phillips points out the necessity of normally lax ligaments at the atlanto-axial joints to allow for normal articular glidding, thus making tonic muscle action the only means by which head stability is obtained.

Strains (Grades 1–3) or indirect muscle injuries are common, frequently involving the erectors. Flexion and extension cervical sprains are also common in sports (Grades 1–3), and usually involve the anterior or posterior longitudinal ligaments, but the capsular ligaments may be involved. In the neck especially, strain and sprain may coexist. Severity varies considerably from mild to dangerous. Anterior injuries are more common to the head and chest as they project further anteriorly, but a blunt blow from the front to the head or chest may result in an indirect extension or flexion injury of the cervical spine. Many cervical strains heal spontaneously but may leave a degree of fibrous thickening or trigger points within the injured muscle tissue. Residual joint restriction following acute care is more common in traditional medical care than under mobilizing chiropractic supervision.

Cervical sprain and disc rupture are associated with severe pain and muscle spasm and are more common in adults because of the reduced elasticity of supporting tissues. Pain is often referred when the brachial plexus is involved. Cervical stiffness, muscle spasm, spinous process tenderness, and restricted motion are common. When pain is present, it is often poorly localized and referred to the occiput, shoulder, between the scapulae, arm or forearm (lower cervical lesion), and may be accompanied by paresthesias. Radicular symptoms are rarely present unless a herniation is present.

Diagnosis and treatment are similar to that of any muscle strain-sprain, but concern must be given to induced subluxations during the initial overstress. Palpation will reveal tenderness and spasm of specific muscles. In acute scalene strain, tenderness and swelling will usually be found. When the longissimus capitis or the trapezius are strained, they stand out like stiff bands.

Extension Injuries. When the head is violently thrown backwards (eg, whiplash), the damage may vary from minor to severe tearing of the anterior and posterior ligaments. Severe cord damage can occur which is usually attributed to momentary pressure from the ligamentum flavum and lamina posteriorly, even without roentgenographic evidence. A facial injury usually suggests an accompanying extension injury of the cervical spine as the head is forced backward. Management of minor injuries requires reduction of subluxations, traction, physiotherapeutic remedial aid, a supporting collar for as long as postural muscles are inadequate for structural support, followed by graduated therapeutic exercises.

Chapter 17:   PERIPHERAL NERVE INJURIES

      Neurotherapy and Spondylotherapy

Neurotherapy refers to the inhibition of overly active nerve function or the activation of sluggish function. Spondylotherapy is the treatment by physical methods applied to the spinal region. A nerve fiber may be stimulated artificially (ie, mechanically, thermally, chemically, electrically) anywhere along its course.

Certain nerve fibers function specifically for certain sensory and motor acts and may be stimulated at either their central or peripheral ends: efferent nerves are stimulated centrally and afferent nerves peripherally. The ability of sensory nerve stimulation to produce a motor or glandular response is readily demonstrated in eliciting any tendon reflex where superficial percussion produces the characteristic jerk, the muscle-spasm reflex resulting from skin exposure to a cool wind or proprioceptive excitement from strain or sprain, or the salivary response from seeing a person eat a lemon.

Neuroinhibition.   Abnormal reflexes appear to be inhibited more by pressure and cold than by any other methods. For example, a painful splinting erectormuscle spasm can be relaxed by placing the muscle in a position of functional rest and then applying mild continuous stretching or pressure. Cold is an excellent neuroinhibitor, especially with nerves which are located not too deep. Functional inhibition can be gained by stimulating a nerve whose chief function is inhibitory. Pressure may be applied digitally or with a pressor instrument at or near the paravertebral spaces. Steady pressure on the surface of the body, usually applied digitally, over the course of a nerve tends to be a restraining influence. There also appears to be a reflex influence upon vessels and glandular secretions. Certain skin areas (eg, suboccipital, paraspinal, parasacral, perianal, peripheral-meridian) are highly responsive to mild pressure from which reflexes of vasodilation and muscle relaxation can be initiated.

Chapter 2:   General Principles of Clinical Neurology

The nervous system and the endocrine system work as partners to provide the majority of functional control for body processes. Guyton, the renowned physiologist, describes the basic function of the nervous system to be the controlling factor for rapid activities such are necessary for muscle contraction, rapidly changing visceral events, and the rate of endocrine secretions.

The dominant action of the nervous system over the physical processes of the body is called neurarchy. In contrast to the nervous system, the endocrine system principally regulates the metabolic functions of the body and controls prolonged physiologic activities.

      OVERVIEW

The demanding role of the nervous system of the human body can be appreciated by recognizing that during every minute of life the nervous system must receive thousands of signals from a countless variety of sensory organs, integrate the data, prepare necessary responses, and effect the responses via a multitude of motor and/or autonomic efferent mechanisms. Thus, a specialized network of nerve tissue permeates the body in such a manner that some parts receive and respond to stimuli from the external or internal environments, some parts transmit signals to and from integrating and coordinating centers, and some parts conduct messages from centers peripherally to muscles, vessels, or glands to effect an action.

Wiles has stated that “Visceromotor articles made up 14% of the ACA Journal of Chiropractic articles in 1977. They made up 8.9% in 1985. If we wanted to, this could be extrapolated out and this type of article would die out by 1992.” If this occurs, a great injustice would be done to the potential of the profession as well as the public it serves. It appears that some in the profession have lost sight of the fact that it was the successful management of visceral and systemic conditions that sustained chiropractic during its early years.

It was the opinion of James Firth, then president of Lincoln Chiropractic College, that chiropractic was a dying profession around the period of World War I. He stated, “There is no question in my mind that it was the successful results of chiropractic during the great influenza epidemic following the war that saved it. Hundreds of thousands of people were dying, and medicine had no solution to the problem. Chiropractors got results, and the word quickly spread throughout the nation. Chiropractic offices that had been nearly empty became filled, and state legislators began to take the chiropractic profession seriously in spite of the opposition of the AMA.”

      OVERVIEW

Embryologically, the somatic structures appear late in development as compared to the vegetative nervous system, which serves as the chief integrating and correlating system of the visceral structures. The voluntary and vegetative nervous systems are intimately connected and brought into reflex connection so that visceral stimulation has skeletal and somatic expression and skeletal muscle messages are expressed in visceral tissues: The body is a whole.

Vegetative action is slow when compared to voluntary action. In addition, human will, at least for normal consciousness without specialized training (eg, biofeedback), has little power to direct visceral effects as one would direct a skeletal muscle because vegetative functions must be conducted whether one is awake or asleep. In certain acts, however, voluntary and vegetative nerves supplement one another such as in swallowing, breathing, defecation, urination, and seminal ejaculation.

Sympathetic Distribution

The sympathetics are widespread in their distribution. Through their innervation of blood vessels, sympathetic fibers reach every tissue of the body. They control blood vessel diameter, subdermal structures, heart muscle, the sphincter system of the gut and urinary apparatus, and parts of the bladder and reproductive organs; they inhibit many structures in the head and chest; and they reach the enteral system’s muscles and glands.

While it is widely recognized that the cervical sympathetic chain communicates with the lower cranial nerves, Parkinson and associates have confirmed that the sympathetic nerve running with the carotid artery gives off a multitude of fine branches at irregular intervals as the nerve travels cephally. The largest residual component joins the cranial VI (abducens) and leaves to join the cranial V (trigeminal) nerve. Similar fibers have not been found to join the cranial III (oculomotor) or IV (trochlear) nerves.

Parasympathetic Distribution

The parasympathetics activate the intrinsic eye muscles, glands of the peripheral head, bronchi muscles and glands, entire enteral system, body of the bladder; they inhibit the heart; and they provide vasodilation in many structures (especially the head and penis).

      STRESS AND THE NEURODYSTROPHIES

An autonomic efferent nerve has two major functions:

(1) impulse conduction and

(2) a trophic influence on receptor organ growth, repair, immunity, and cellular alterations in disease.

While these conduction and trophic functions are of equal importance and separate actions, trophic functions have unfortunately received secondary interest by most research neurologists. Because interference with trophic function serves an important role within chiropractic concepts, several pertinent findings are described in this section.

Research on nonimpulse initiated communication between the neuron and its end structures has increased in recent years. Singer relates that despite considerable controversy modern consensus accepts the role of neurotrophic and impulse stimulation in the maintenance of muscle tissue. He feels that, experimentally, it has been difficult to report these two mechanisms for individual study because most information has been obtained in model systems.

Autoadaptation and Immunity

Guth, Gutmann, and Gurkalo/Zabezhinski show that there should be no question that the autonomic nervous system regulates directly and indirectly the functions of all organs and tissues and influences even biochemical processes at the cellular and subcellular level.

After observing more than 15,000 patients with infectious diseases and studying the host-parasitic relation in infectious disease, Sato found that the adaptation of the human body to the internal environment is maintained by an autoadaptation mechanism operating upon the biological binary digit. That is, the autoadaptation mechanism has two antagonistic systems (sympathetic and parasympathetic divisions) that are composed of many antagonistic links:

(1) the two reciprocal nerves of the autonomic nervous system;

(2) two phases (rise and fall) of mitosis of the neurotrophic system in bone marrow; and

(3) two defense reactions (the cell-stimulant factor reaction and the antibody-antigen reaction).

These binary antagonistic links are interconnected into two systems that are controlled by the two antagonistically functioning nerves (sympathetic and parasympathetic) of the autonomic nervous system.

In a following study, Sato found that the autoadaptation mechanism of the human body loses its rationality and purposefulness by an imbalance of the autonomic nervous system, and the host body falls into adaptational disturbances. He reports that hosts with sympathicotonia often fall into acute adaptational disturbances in the acme to the convalescent stage by stimuli of the second-phase factors (the factors lowering mitosis of the neurotrophic system in the bone marrow), resulting sometimes in death.
