Acute carpal tunnel syndrome secondary to septic arthritis of the wrist.

A case of acute carpal tunnel syndrome secondary to septic arthritis of the wrist is reported. Treatment consisted of carpal tunnel release, incision and drainage of the wrist joint, intravenous injection of antibiotics, and delayed primary closure. The infection resolved and median nerve function promptly returned to normal. We believe this is the first report of septic arthritis of the wrist as a cause of acute carpal tunnel syndrome.
