Prospective clinical and electrophysiological studies before and after anterior transposition of the ulnar nerve

ABSTRACT

Clinical and electrophysiological studies were performed for 41 patients [43 elbows] with tardy ulnar neuritis before and after subcutaneous anterior transposition of the ulnar nerve, with an average of 15 +/- 9.8 months follow up. Multiple mechanical causes for neuropathy were identified. Subjective improvement after the operation was obtained in more than 80% of the cases. The chance of recovery after the operation was greatly affected by preoperative symptoms period and the pathology which was present in the ulnar nerve and/or in the elbow, but seemed to be independent of the patient age
