Injuries to the finger extensor apparatus are very common and may produce chronic deformity and loss of function. Diagnosis is contingent on an understanding of the complex anatomy of this region as well as the ability to perform a careful physical examination. Immobilization is usually the most effective treatment of acute problems. Surgery is often necessary for chronic conditions, but the results are much less predictably corrective.
