Efficacy comparison between anterior subcutaneous and submuscular transposition of ulnar nerve in treating moderate-severe cubital tunnel syndrome

摘要

OBJECTIVE:To explore the optimal surgery in treating moderate-severe cubital tunnel(CuTS) syndrome by comparing the clinical efficiency of decompression and anterior subcutaneous transposition of ulnar nerve and decompression and anterior submuscular transposition of ulnar nerve,and to provide a theoretical basis for the appropriate surgical programs in treating moderate-severe Cu TS.METHODS:47 consecutive cases of moderate-severe Cu TS were surgically treated in our department from January 2014 to January 2017.All patients were divided into two groups by the doctor in our department.21 Cu TS cases were treated with decompression and anterior subcutaneous transposition of ulnar nerve,and other 26 cases were treated with decompression and anterior submuscular transposition of ulnar nerve.All the patients were followed 1 month,3 months and 6 months after operation to evaluate the recovery degree of ulnar nerve function and the clinical efficiency of the two methods was compared.RESULTS:Clinical symptoms of two groups were significant alleviated.There was no significant statistical difference between two groups in the clinical efficiency.CONCLUSION:Completely releasing of nerve truck is the most important step in treating mediate-severe Cu TS.Theclinical results of the two methods are similar,but the anterior subcutaneous transposition of ulnar nerve is more easy to operate and can be widely used.
