Review of Anterior Submuscular Transposition of Ulnar Nerve for Cubital Tunnel Syndrome

In this study, we report the results of patients who underwent ulnar nerve submuscular anterior transposition surgery due to cubital tunnel syndrome.Data of 46 patients who underwent anterior submuscular transposition surgery due to cubital tunnel syndrome between January 2010 and December 2014 were retrospectively reviewed. Twenty-seven patients with preoperative and postoperative complete medical records available and who had completed at least 24 months follow-up were included in the study.According to preoperative McGovan staging system, 1 patient was classified as stage 1, 8 were stage 2A, 3 were stage 2B, and 15 were stage 3. The mean follow-up time was 61.4 (35-88) months. The mean DASH score of the patients was calculated as 19 (0-81.81). Mayo elbow performance score was excellent in 13 patients, good in 7, fair in 6, and poor in 1.Anterior submuscular transposition of ulnar nerve had resolved symptoms 89% of our patients. The technique is a successful method with a low recurrence and complication rate.
