Extensor Tendon Injuries in the Hand.

Until recently, extensor tendon injuries were often discounted as an important hand problem. However, studies have shown that not all extensor lacerations fare well and that loss of flexion can be problematic. Newer postoperative protocols emphasizing tendon gliding have improved results, and better repair techniques and postoperative rehabilitation regimens are under investigation. This article reviews the evaluation of acute open and closed extensor tendon injuries, their conservative and surgical treatment, and postoperative rehabilitation options.
