Abstract: | PURPOSE: Four-corner arthrodesis with scaphoid excision has been used to reduce pain and preserve functional range of motion for patients with radioscaphoid arthritis. Early results of 4-corner arthrodesis with scaphoid excision using dorsal circular plate fixation are compared with reported results in the literature. METHODS: We reviewed retrospectively the first 18 four-corner arthrodeses performed with this system by 4 hand surgeons. Two patients had revision surgery for nonunions before the study that were considered failures. Eight patients returned for final radiographs, objective examination, and functional questionnaire. The average follow-up period was 20 months (range, 13-33 mo). These results were compared with reported results in the literature using alternate fixation methods. RESULTS: Radiographic union was achieved in only 3 wrists. Range of motion was 46% that of the opposite normal wrist and grip strength compared with the opposite wrist was 56%. Five patients would have the procedure again and 6 of 8 have returned to their original employment. CONCLUSIONS: Four-corner arthrodesis with scaphoid excision using a circular internal fixation plate produced a high number of nonunions. Grip strength and range of motion results also were inferior to those reported in the literature. |
