In this podcast. Dr. Larry Hurst takes you through details of Gamekeeper's Thumb.

Gamekeeper’s thumb, also referred to as skier’s thumb, is an avulsion or rupture of the ulnar collateral ligament (UCL) of the metacarpophalangeal (MP) joint of the thumb, resulting in joint instability. It was originally described by CS Campbell1 and the mechanism of injury is forced radial deviation (abduction). Patients can present with a broad range of ulnar instability. In 1962, Stener described a series of patients with complete rupture of the UCL, and during surgery he found the adductor aponeurosis interposed between the distally avulsed UCL and its insertion at the base of the thumb. He concluded that unless contact was restored at the site of rupture, healing would result in a lax ulnar capsule, regardless of the period of immobilization.
