title: The role of epineurotomy in the operative treatment of carpal tunnel syndrome.
abstract: We conducted a prospective, randomized study to evaluate the effect of epineurotomy on the outcome of operative treatment of established median-nerve compression in the carpal canal. Fifty hands (forty-four patients) were randomized into two groups: one group had a release of the transverse carpal ligament alone, and the other had a release and adjuvant epineurotomy of the median nerve. The groups were similar with regard to age, gender, duration of symptoms, and preoperative physical findings. All patients had electrophysiological evidence of sensory delays and fibrillations on preoperative testing. All of the operative procedures were performed by the same surgeon. The patients were evaluated preoperatively and at one year postoperatively. The follow-up examination revealed no detectable differences between the two groups with regard to symptoms, objective findings, or electrophysiological findings. This suggests that epineurotomy of the median nerve offers no benefit compared with sectioning of the transverse carpal ligament alone.
