Extensor Tendon Centralization at the Metacarpophalangeal Joint: Surgical Technique

Injury to the extensor hood at the level of the dorsal metacarpophalangeal joint with instability and subluxation of the extensor tendon might require surgical treatment after failing conservative methods. Surgical techniques for chronic injuries have used local tissue or nearby tendon slips as grafts for tendon realignment, with or without soft tissue release and imbrication. Here we present a technique that creates a bone tunnel for a graft that is sutured upon itself and effectively creates a new pulley.
