Comparison of Simple Decompression and Anterior Subcutaneous Transposition of the Ulnar Nerve for the Treatment of Cubital Tunnel Syndrome

Abstract

Background. In this study, we aim to evaluate clinical and functional results in patients with cubital tunnel syndrome who were treated with subcutaneous anterior transposition vs simple decompression of the ulnar nerve. Material and methods. Fifty-five patients were separated into two groups according to surgical technique. Group 1 comprised 35 patients (23 males, 12 females; mean age, 42.1 years; range, 28–56 years) who underwent anterior subcutaneous transposition of the ulnar nerve, whereas Group 2 included 20 patients (11 males, 9 females; mean age, 47.4 years; range, 25–59 years) who underwent simple decompression of the ulnar nerve. Results. The mean modified Bishop scores were 7.26 and 7.85 in Group 1 and Group 2, respectively (P< .05). The mean Q-DASH scores were 16.94 in Group 1 and 15.80 in Group 2 (P> .05). Postoperatively, paraesthesia regressed in 17 (85.7%) and 30 (85%) patients in Group 1 and Group 2, respectively (P> .05). Both groups demonstrated improvement in ulnar nerve function in comparison with the preoperative period, and ulnar nerve paralysis was not seen in any of our patients. A postsurgical incision scar developed in six (17.1%) and three patients (15%) in Group 1 and Group 2, respectively. Conclusion. Both simple decompression and anterior subcutaneous transposition of the ulnar nerve are effective and safe for the treatment of cubital tunnel syndrome, so we would favour simple decompression as it is a less extensive procedure.
