Surgical treatment of 35 volar Barton fractures. No need for routine decompression of the median nerve

35 patients with volar Barton fractures were treated operatively from 1985-1994. The injury was due to a high velocity motor vehicle accident in 20 patients. All fractures were closed without major carpal injuries. 11 fractures were type B3.1, 21 type B3.2 and 3 type B3.3. according to the AO classification. All fractures were openly reduced and internally fixated by small buttress plates and screws. In 31 cases, the median nerve was unaffected by the injury and was not explored or decompressed during surgery. The patients were assessed clinically and radiographically after mean 6 (2-10) years. According to the criteria of Pattee and Thompson (1988), 23 patients had excellent results, 10 good and 2 fair. Posttraumatic arthrosis was found in 12 patients and was related to the congruency of the articular surface achieved at surgery. We conclude that the median nerve, when not damaged or compressed, should not be explored or decompressed during surgery.
