A Stener lesion is seen in the context of a torn ulnar collateral ligament of the thumb's metacarpophalyngeal joint (gamekeeper's thumb).
It is characterised by dislocation of the torn end of the ligament dorsally above the adductor aponeurosis / adductor pollicis muscle such that it is separated from the joint. This prevents healing and is an indication for surgical repair.
Full evaluation requires abduction stress views and an increase of more than 30° in the angle between the 1st metacarpal and proximal phalanx indicates subluxation.
First described by B Stener in 1962 3-4.
