Thirty-six patients with arthrosis of the carpometacarpal joint of the thumb were treated, 19 patients by resecting the trapezium and interposing a tendon, 17 patients by replacing the resected trapezium with silastic prosthesis (Swanson). The follow-up time was in average 22 respectively 44 months; both groups were comparable. The patients treated by resection of the trapezium and tendon interposition were more satisfied and had less pain than those treated by implantation of a Swanson prosthesis. There was no difference in mobility and strength of pinch between the two groups. After resection of the trapezium and tendon interposition the authors found a proximal translocation averaging 7 mm (6 to 14), however these patients had a good functional result and no pain. Five patients had a luxation of the Swanson prosthesis, and four required a second operation.
