Skeletal view of hand, with detail of complete tear of ulnar collateral ligament in thumb

Skier's (or gamekeeper's) thumb results from a tear of the ulnar collateral ligament of the thumb. This injury can happen when your thumb is pulled back or to the side, away from your fingers. It often happens when a skier falls on an outstretched hand that is holding a ski pole. The tear can be partial or complete.
