Ulnar nerve compression at the elbow level

The long-term results are reported (average 9 years) of anterior transposition of the ulnar nerve into a muscular groove in the treatment of ulnar nerve compression at the elbow level. The series of 27 elbows consisted mostly of patients with muscle deficit. The results were examined in relation to the preoperative duration of symptoms, particularly weakness and wasting of muscles, and were satisfactory in 78% of cases in that recovery of the muscle deficit was either complete or showed marked improvement. When the duration of symptoms exceeded one year, the results were less satisfactory.
