Carpal tunnel syndrome: electrophysiological grading and surgical results by minimum incision open carpal tunnel release.

摘要: The safety and effectiveness of the minimum incision technique were assessed in 138 hands 108 consecutive patients with carpal tunnel syndrome treated from April 1, 1997 to March 31, 2006. Clinical electrophysiological examinations conducted before after surgical decompression. All divided into early, mild, moderate, severe groups based on preoperative severity. We examined outcomes affected each group. Nocturnal or daytime dysesthesia, which had been present 132 (96%) preoperatively, was completely relieved 124 (94%) hands. Complete relief achieved 7 (100%) early group, 68 (99%) 69 mild 45 48 moderate only 4 (50%) 8 3 (38%) did not show any improvement. No painful hypertrophic scar formation observed this series. Only 2 complained postoperative discomfort more than 12 months, disappeared by 14 months surgery. Minimum open release is a safe reliable procedure high rate functional improvement patient satisfaction. Postoperative results satisfactory regardless degree severity if sensory nerve action potentials detected.
