title: Tendon ruptures and median nerve damage after Hamas total wrist arthroplasty.
abstract: This article describes complications due to an incorrectly positioned Hamas-designed total wrist prosthesis in a 68-year-old woman with rheumatoid arthritis. At operation the median nerve was found to be directly impinged upon by the rim of the distal portion of the prosthesis. There were divisions of the superficialis tendon to all four fingers, the profundus tendon to the index finger, and partial division of the profundus to the long finger. The prosthesis was removed, and the wrist stabilized with a Steinmann pin in the radius and the second metacarpal.
