Arthroscopic Ulnar Nerve Decompression (SS-54)

Abstract

To report our results with an arthroscopic technique for ulnar nerve decopression. A retrospective review of a single surgeon series of arthroscopic ulnar nerve releases associated with other arthroscopic elbow procedures. From April of 2007 to January of 2011, fifty nine elbow arthroscopies were performed by the surgeon; sixteen patient hand an arthroscopic ulnar nerve decompression as part of the surgery; no isolated arthroscopic nerve decompressions were performed. All patients were available for clinical and radiographic follow-up at an average of 16 months (range 3-24). Average preoperative range of motion was 25.4o of extension to 112.3o of flexion. Average postoperative range of motion was 9.6o of extension to 130o of flexion, a gain of 15.8o and 17.7o respectively. Thirteen patients remain very satisfied with their elbow surgery. Three patients underwent a subsequent elbow surgery: one total elbow (in a rheumatoid), and two formal ulnar nerve transpositions. Arthroscopic ulnar nerve decompression can be performed successfully. The technique is demanding and revision demonstrates significant scaring around the nerve. One case had a significant neuroma as a result of the arthroscopic procedure. With the ease of an isolated decompression through a small incision, the arthroscopic approach may not be the procedure of choice.
