gamekeeper's thumb

An avulsion fracture at the ulnar base of the proximal phalanx of the thumb, linked to the ulnar collateral ligament of the metacarpophalangeal joint; GT occurs in 'week-end warriors', ie football or skiing injuries–as in a twisted ski pole, often due to falls Features Valgus instability, treated by a cast in adduction; if point instability is marked, open repair of ligament

(gām'kēp-ĕrz thŭmb)
Rupture of the volar ligament at the first metacarpophalangeal joint due to forceful abduction of the thumb while extended.

skier's thumb

a colloquial expression used in sports medicine to describe instability of the metacarpophalangeal joint caused by forced abduction whilst the thumb is extended (e.g. holding the ski stick in a fall); this stretches or ruptures the ulnar collateral ligament which normally limits movement of the thumb away from the hand. Also known as gamekeeper's thumb since similar damage was caused by breaking the neck of birds or rabbits held between finger and thumb.
