ABSTRACT
PURPOSE: To evaluate the surgical outcomes and the clinical factors affecting the results of subcutaneous anterior transposition of the ulnar nerve in cubital tunnel syndrome. MATERIALS AND METHODS: Eighteen patients diagnosed as having cubital tunnel syndrome and treated by subcutaneous anterior transposition of ulnar nerve were investigated retrospectively. According to preoperative Dellon's staging, 2 patients (11%) were in mild stage, 5 (28%) in moderate and 11 (61%) in severe. Results were evaluated using Dellon's staging and Mowlavi's classification. RESULTS: According to Mowlavi's outcome status, 2 patients (11%) showed total relief, 10 (56%) improvement, 5 (28%) no change and 1 (6%) was worse, therefore the results were satisfactory in 12 patients (67%). Patients with less severe symptoms received surgery within a year of symptom onset and showed better results. CONCLUSION: The result of subcutaneous anterior transposition of ulnar nerve in cubital tunnel syndrome is comparable to that of other surgical methods, but it is easier technically. Better results may be anticipated when surgery is performed within a year of symptom onset.
