[Cubital tunnel syndrome: a retrospective review of 55 subcutaneous transpositions with minimum 3-year follow-up].

The surgical management of the cubital tunnel syndrome has no strict rules to follow. Surgical treatments are various, but none of them has been shown to be superior to the others. This retrospective study presents the clinical results in 73 patients who underwent an anterior subcutaneous transposition of the ulnar nerve, between January 2000 and January 2010, with a minimum 3-year follow-up. Fifty-five patients were assessed with an average follow-up of 65.7 months. McGowan grading system as modified by Goldberg was used to analyse clinical results, preoperatively and at follow-up. The DASH score was used to assess physical function. The average preoperative evolution of symptoms was 16.7 months, and mean period to resolution was 4.7 months. The grade in McGowan grading system as modified by Goldberg significatively improved at follow-up (P=0.0002). Only five patients kept paresthesia. The mean postoperative DASH score was 7.27/100. The satisfaction rate was 96%, and all the patients except one returned back to their occupation. There was neither infection nor complex regional pain syndrome. The anterior subcutaneous transposition leads to very good clinical results, satisfaction and physical function. It is an effective surgical method, without complication in our study, which gives long-term results.
