title: Long-term results of carpal tunnel release.
abstract: To determine the long-term results of carpal tunnel release, we retrospectively reviewed 60 cases, an average of 5.5 years after surgery. 87% reported a good or excellent overall outcome; the average time to maximum improvement of symptoms was 9.8 months. However, 30% reported poor to fair strength and long-term scar discomfort, and 57% noted a return of some pre-operative symptoms, most commonly pain, beginning an average of 2 years after surgery. We found no correlation between pre-operative symptoms or extent of surgical dissection (internal neurolysis) and outcome. Carpal tunnel syndrome was job related in 42%; of these, 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 found significant morbidity from the surgical scar and decreased strength, and often considerable delay until ultimate improvement, especially in patients with job-related carpal tunnel syndrome.
