Skier's Thumb

Skier’s thumb is an injury to the collateral ligaments of the thumb, most commonly the ulnar collateral ligament (UCL) at the base of the thumb. This injury may occur due to overuse or a traumatic event, such as a fall onto an outstretched hand while holding a ski pole. The ligament can be partially torn or completely ruptured. In the case of a complete rupture, surgery is usually required as the stability of the thumb is significantly compromised, severely affecting grip strength and function. Partial tears, however, typically heal well without surgical intervention and respond effectively to conservative management, including rest, splinting, and physiotherapy.
