Camptodactyly.

Camptodactyly is a congenital difference with flexion contracture of the proximal interphalangeal (PIP) joint. Camptodactyly limited to one finger is believed to be due to an anomaly of the lumbrical muscle that inserts into the flexor digitorum superficialis (FDS) tendon instead of the extensor expansion, whereas multiple finger camptodactyly is believed to be a result of shortage of soft tissues on the flexor surface of the fingers. It is important to differentiate camptodactyly from other causes of extension lag at the PIP joint. It is difficult to obtain good results after the release of flexion contractures in camptodactyly. The main goal of surgery is to prevent progressive contracture with appropriate postoperative therapy using night splinting and stretching. We should strive for a considered approach based on a thorough understanding of the pathophysiology of camptodactyly. Level of Evidence: Level V (Therapeutic).
