The treatment of ulnar nerve compression at the elbow remains controversial. No single technique has yet proven its superiority. We describe a technique combining the advantages of the mini-invasive approach with those of transposition. We present the results of 30 patients, of mean age 52 years, who underwent anterior subcutaneous transposition of the ulnar nerve using a mini-invasive approach with a follow-up of more than six months. The incision measures 3 cm. The results were evaluated by measuring pain intensity, quick disabilities of the arm shoulder and hand (DASH), grip strength and pinch, and McGowan score, pre- and post-operatively. All parameters were improved post-operative. The mean pain score went from 5.5 to 4, the quick DASH from 48 to 38, mean grip strength from 28 to 31 kg, and mean pinch strength from 4.7 to 6.4 kg. The McGowan score was also improved; pre-operatively, there were 16 patients at stage III, seven patients stage II, seven patients stage I, and post-operatively there was one patient stage III, three patients stage II, 16 patients stage I, and 10 patients stage 0. Analysis of our series shows that a 3 cm incision without endoscopy allows subcutanous transposition, with results at least as good as those with other techniques. The advantages of our technique are that it is easy, has a limited approach, preserves blood supply, allows placement of the nerve in a favourable environment, and decreases nerve stretching during elbow flexion.
