[Endoscopic decompression of the median nerve in the carpal tunnel. Apropos of 1,400 cases].

We report the results of endoscopic carpal tunnel release in 1,400 patients over a two year period (minimum 6-month follow-up). All patients were operated on using a technique derived from that of Chow. Complications were limited to two partial lesions of the superficial palmar arch and one interdigital nerve lesion. The technique is described. Analysis of the results indicates the advantages of this method. Though immediate post-operative comfort was greater and restoration of the grip quicker, the results were roughly similar to those of the classic method in the 6 months following surgery. Sympathetic dysfunction represented only 0.28% of cases. Patients generally returned to work earlier than with the classic technique. This method does not replace the conventional technique for certain indications. The authors emphasize the difficulties involved and recommend that this method be used only by experienced surgeons and aware of intra-operative risks.
