Contusions and Lacerations

Highly painful compression injuries can severely damage all
Contusions of the dorsal aspect of the hand usually come from
being stepped on
when down. Cleats, sticks, and skate blades, obviously, increase
of the injury.
Two conditions are involved here that may be separate or superimposed:
Distraction of the metacarpal ligament may result in boxer's having their hands taped in full extension when the intermetacarpal ligaments are relatively slack. As the hand is flexed, the ligaments tighten and the fingers are forced into apposition, which can cause ligamentous distraction if any material becomes inserted between the fingers.
After trauma, a bursa may form over a metacarpal head and become chronically inflamed.
It is not uncommon for karate enthusiasts to scarify their
hands and feet
by striking a straw-covered pliable post (makiwara) in several

abused by such a severe form of hand conditioning show no visible
calcification or damage to the metacarpal heads.

Finger and Thumb Strains
The most common trigger point found in the hand is that of the
pollicis, and the most common area of referred trigger-point pain
in the hand
is found at the distal 24 metacarpal area.
Chronic contraction of palmar fascia (and/or sometimes the
of the feet) leading to a flexion deformity of the distal palm

painless distortion of the little finger in one or both hands. A

Management Considerations. A sprained finger joint usually produces painful tears of a collateral ligament, and capsulitis is a common complication. The common procedure is to immobilize in moderate flexion, and
treat as a severe sprain. Graduated exercises may begin in about
This classic deformity consists of:
(1) metacarpophalangeal hyperextension,
(2) proximal interphalangeal flexion, and

injury mechanism is usually severe finger flexion causing proximal interphalangeal
joint disruption leading to severe contractures. Besides a

Management Considerations. Conservative care is frequently effective when trauma is the origin. Cold should be applied throughout the inflammatory stage. Once pain and swelling have been controlled, a common procedure is to
immobilize the involved proximal interphalangeal joint(s) in full extension for 2 months or more. This is followed by night splints for another 2 months. Splinting should continue until there is full joint extension and nearly half
of normal flexion. If an extension deficit remains, surgical referral should be considered.
