- PURPOSE: The purpose of this investigation was to extend the previously reported short-term randomized trial of open and endoscopic carpal tunnel release in patients with carpal tunnel syndrome (CTS) to compare outcomes 5 years after surgery. METHODS: In a single-center randomized controlled trial, 128 patients (25 to 60 years) with clinically diagnosed and electrophysiologically confirmed idiopathic CTS were randomized immediately before surgery to open or 2-portal endoscopic release. The outcome measures included the validated CTS questionnaire's symptom severity and functional status scales (scored from 1 to 5) completed at baseline and 1 year postoperatively. At the extended follow-up of the trial 5 years after surgery, 2 patients had died and the other 126 participants (63 patients in each group) completed the CTS questionnaire. RESULTS: At the 5-year follow-up no difference between the groups was found in the CTS symptom severity score. The mean (SD) score in the open group was 1.42 (0.7) and in the endoscopic group was 1.45 (0.7), and the mean difference in score change from baseline was 0.03 (95% confidence interval, -0.21 to 0.27). Between 1 year and 5 years postoperatively, the CTS symptom severity score had deteriorated by at least 0.4 point in 9 patients in the open group and in 10 patients in the endoscopic group. The mean (SD) CTS functional status score was 1.29 (0.5) in the open group and 1.30 (0.5) in the endoscopic group. At 5 years, 11 patients in the open group and 10 patients in the endoscopic group reported persistent pain in the scar or proximal palm. Three patients in each group had repeat surgery on the operated hand because of persistent or recurrent symptoms. CONCLUSIONS: The improvements in symptoms of CTS and hand-related disability 5 years after open and 2-portal endoscopic carpal tunnel release were equivalent. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

- Objectives To compare endoscopic and open carpal tunnel release surgery among employed patients with carpal tunnel syndrome. Design and setting Randomised controlled trial at a single orthopaedic department. Participants 128 employed patients aged 25-60 years with clinically diagnosed and electrophysiologically confirmed idiopathic carpal tunnel syndrome. Main outcome measures The primary outcome was severity of postoperative pain in the scar or proximal palm and the degree to which pain or tenderness limits activities, each rated on a 4 point scale, transformed into a combined score of 0 (none) to 100 (severe pain or tenderness causing severe activity limitation). The secondary outcomes were length of postoperative work absence, severity of symptoms of carpal tunnel syndrome and functional status scores, SF-12 quality of life score, and hand sensation and strength (blinded examiner); follow-up at three and six weeks and three and 12 months. Results 63 patients were allocated to endoscopic surgery and 65 patients to open surgery, with no withdrawals or dropouts. Pain hi the scar or proximal palm was less prevalent or severe after endoscopic surgery than after open surgery but die differences were generally small. At three months, pain in the scar or palm was reported by 33 patients (52%) in the endoscopic group and 53 patients (82%) in the open group (number needed to treat 3.4,95% confidence interval 2.3 to 7.7) and the mean score difference for severity of pain in scar or palm and limitation of activity was 13.3 (5.3 to 21.3). No differences between the groups were found in the other outcomes. The median length of work absence after surgery was 28 days in both groups. Quality of life measures improved substantially. Conclusions In carpal tunnel syndrome, endoscopic surgery was associated with less postoperative pain than open surgery, but the small size of the benefit and similarity in other outcomes make its cost effectiveness uncertain.
