Treatment of the Cubital Tunnel Syndrome by Modified Eaton's Method of Anterior Transposition of Ulnar Nerve with Fasciodermal Sling

ABSTRACT

We evaluated the postoperative results of cubital tunnel release with modified Eaton's method of anterior transposition of ulnar nerve using fasciodermal sling. This study included 12 patients. According to Dellon's classification, patients were categorized 3 groups as mild(n=2), moderate(n=6), and severe(n=4). Through the longitudinal incision on the medial aspect of the elbow, ulnar nerve was released both proximally and distally. And then, ulnar nerve was wrapped with fasciodermal sling about 3 4 cm in size, which was elevated from the fascia of the common origin of the flexor and pronator muscles. Postoperative results were assessed by modified Kleinman and Bishop's rating system. There were excellent in 4 patients(33%), good in 7 patients(58%) and fair in 1 patient(9%). No patient complained of tingling sensation of the ring and/or small finger. Although all patients showed some improvement of key- pinch, grip-power and static 2-point discrimination, those were not statistically significant. Finally, this procedure has advantages as simple operative technique, short postoperative immobilization, and brief rehabilitation period.
