Subcutaneous or Submuscular Anterior Transposition of the Ulnar Nerve?

Abstract

Precise clinical and electroneurographic examinations were made of 51 patients before and after anterior transposition of the ulnar nerve. The mean follow-up period was 9.6 years. In 86%, hand function improved, while in 10% it remained unchanged. Subcutaneous transposition was better than submuscular transposition, especially with regard to sensation. This method is simple and involves low morbidity for patients.
