Diagnosis: UCL Tear with Stener Lesion Tear of the UCL of the thumb MCP joint is also called “gamekeeper’s thumb” or “skier’s thumb.”

Tear most commonly occurs at the proximal phalangeal insertion, sometimes resulting in an avulsion fracture.

When the torn UCL is significantly retracted and entrapped superficial to the adductor aponeurosis, it is referred to as a “Stener lesion.”

Stener lesions require surgical repair.
