[Ulnar nerve compression syndrome of the elbow. Analysis of 50 operated cases].

This is a retrospective review of 50 elbows (44 patients) treated operatively by simple decompression (seven cases), decompression with epitrochlectomy (13 cases), and anterior transposition (30 cases) for compression neuropathy of the ulnar nerve at the elbow. We performed a superficial transposition in five cases, an intramuscular transposition in 13 cases, and a deep submuscular transposition in 12 cases. The mean follow-up was three years and two months. The overall results show cure or improvement in 78% of cases, no changes in 20% of cases, and one case with subjective worsening. The postoperative result was inversely proportional to the initial degree of the neuropathy. The cases related to trauma obtained a better result.
