Traumatic tenosynovitis and extensor tendon rupture.

Extensor tenosynovitis is caused by a variety of conditions, but most commonly is associated with inflammatory arthritis. Extensor tenosynovitis with secondary tendon rupture due to occupational repetitive direct trauma to the dorsal compartments of the wrist and hand is reported in a woman. Tenosynovectomy and tendon transfer were performed to relieve pain and restore hand function.
