The skiier’s thumb is a serious injury to the strong ulnar collateral ligament of the thumb. It is usually the result of falling onto the hand while holding a ski-pole, causing the thumb to be bent outwards. It can result from common falls around the house as well. This injury needs to be diagnosed early and is usually treated surgically by reattaching the torn ligament. If left untreated, it can result in a painful, weak, and unstable thumb.
