Carpal tunnel syndrome: electrophysiological grading and surgical results by minimum incision open carpal tunnel release.
The safety and effectiveness of the minimum incision technique were assessed in 138 hands of 108 consecutive patients with carpal tunnel syndrome treated from April 1, 1997 to March 31, 2006. Clinical and electrophysiological examinations were conducted before and after surgical decompression. All hands were divided into early, mild, moderate, and severe groups based on preoperative electrophysiological severity. ⋯ Only 2 patients complained of postoperative scar discomfort after more than 12 months, which completely disappeared by 14 months after surgery. Minimum incision open carpal tunnel release is a safe and reliable procedure with a high rate of functional improvement and patient satisfaction. Postoperative results were satisfactory regardless of the degree of preoperative electrophysiological severity if preoperative sensory nerve action potentials were detected.
