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.
