Carpal tunnel syndrome is a common condition causing hand pain and numbness. Endoscopic carpal tunnel release has been demonstrated to reduce recovery time, although previous studies have raised concerns about an increased rate of complications. The purpose of this study was to compare open carpal tunnel release with endoscopic assisted carpal tunnel release. Methods: The study was performed on 52 hands in 40 patients. The open method was used in 27 hands in 19 patients, and the endoscopic assisted method was used in 25 hands in 21 patients. All of the patients had clinical signs or symptoms consistent with carpal tunnel syndrome and had not responded to non operative management. Follow-up evaluations were performed at three, six, twelve, twenty-four, and forty-eight weeks after the surgery. The time until return to work were recorded and compared between the groups. Results: During the first three months after surgery, the patients treated with the endoscopic assisted method had better Carpal Tunnel Syndrome Symptom Severity Scores, better Carpal Tunnel Syndrome Functional Status Score, they also had significantly (p < 0.05) greater grip strength. The open technique resulted in greater scar tenderness during the first three months after surgery as well as a longer time until the patients could return to work (median, thirty-five days compared with sixteen days after the endoscopic assisted release). No technical problems with respect to nerve, tendon, or artery injuries were noted in either group. There was no significant difference in the rate of complications between the two groups. Conclusion: Good clinical outcomes and patient satisfaction are achieved more quickly when the endoscopic assisted method of carpal tunnel release is used. Small transverse wrist incision with the use of endoscope is a safe and effective method of treating carpal tunnel syndrome. |
