[Endoscopic release of the ulnar tunnel. Technique and clinical-functional outcomes].

INTRODUCTION

The ulnar tunnel syndrome is the second compressive neuropathy, followed by the carpal tunnel, making it a frequent reference in hand surgery. There are few published studies about endoscopic technique.

MATERIAL AND

METHODS

We studied 26 patients with ulnar tunnel syndrome diagnosis, were operated by endoscopic release of the ulnar tunnel. Nine women (35%) and 17 (65%) male patients. We used the modified McGowan, and the Wilson and Krout classification to analyze preoperative and postoperative variables.

RESULTS

After endoscopic decompression we obtained 18 patients (69%) with excellent evolution, 6 (24%) with good evolution, and 2 (7%) with acceptable outcome. We obtained a significant p of 0.05.

CONCLUSION

Endoscopic decompression of the ulnar tunnel is a safe technique, less invasive and with good outcome.
