Skier's Thumb is an acute condition that is acquired after a fall or similar abduction injury to the MCP joint of the thumb. Gamekeeper’s thumb – chronic condition Develops as a result of repeated episodes of hyperabduction When the injury occurs, a tear or possible avulsion of the ligament may occur at the site of insertion into the phalanx of the thumb. Stener lesion. Stener lesions are seen in the context of a torn ulnar collateral ligament of the thumb 's metacarpophalangeal joint ( gamekeeper's thumb ). Stener lesion: Proximal end of the ligament becomes trapped superficial to the adductor pollicis aponeurosis. It is a common sporting injury. It is vital to examine the other normal thumb first and assess the range of motion and valgus stability; only then should the injured thumb be examined. In these patients, the distal attachment of the UCL was traumatically avulsed from its site of insertion at the base of the proximal phalanx of the thumb. When the ulnar collateral ligament is retracted and displaced proximally superficial to the adductor aponeurosis or fascia, this is referred to as Stener lesion. Figure 1. In 1962, Bertil Stener described a lesion which he observed to occur in a subset of patients suffering from gamekeeper's thumb.
