LONG-TERM RESULTS OF CARPAL-TUNNEL RELEASE

To determine the long-term results of carpal tunnel release, we retros pectively reviewed 60 cases, an average of 5.5 years after surgery. 87 % reported a good or excellent overall outcome; the average time to ma ximum improvement of symptoms was 9.8 months. However, 30% reported po or to fair strength and long-term scar discomfort, and 57% noted a ret urn of some pre-operative symptoms, most commonly pain, beginning an a verage of 2 years after surgery. We found no correlation between pre-o perative symptoms or extent of surgical dissection (internal neurolysi s) and outcome, Carpal tunnel syndrome was job related in 42%; of thes e, 26% changed from heavy to lighter work following surgery. Although occupational cases were slower to improve and remained off work longer , the long-term subjective results were the same for both groups, We f ound significant morbidity from the surgical scar and decreased streng th, and often considerable delay until ultimate improvement, especiall y in patients with job-related carpal tunnel syndrome.
