Surgical treatment of cubital tunnel syndrome has been reported according to a wide variety of techniques since the end of the last century. Theses range from simple decompression to various forms of nerve transposition and medial epicondylectomy. However, we could find only few reports which compare the results between different types of operations. The treatment results of medial epicondylectomy and anterior subcutaneous transposition, were analysed retrospectively. From March 1984 to January 1996, a total of 110 patients had operations for cubital tunnel syndrome. Seventy four of them were followed-up for more than one year, and only they were included in this study. Anterior subcutaneous transposition was performed in 26 patients; and medial epicondylectomy in 48 patients. There were 52 males and 22 females, with an average age of 34 years (range, 13 to 75). The average follow-up period was 40 months (range, 12 to 132). Grading system by Gabel and Amadio were used for evaluation of the patients; pain, sensory and motor dysfunction were checked preoperatively and at last follow-up. In 26 patients of anterior subcutaneous transposition, 7 (27%) were graded as excellent, 11 (42%) good, 3 (12%) fair and 5 (19%) poor. In 48 patients of medial epicondylectomy, 16 (34%) were excellent, 27 (56%) good, 3 (6%) fair and 2 (4%) poor. Sixty nine percent were excellent or good in anterior subcutaneous transposition group, while ninty percent in medial epicondylectomy group. This difference was significant statistically (p<0.01 )., From our experiences, we suggest medial epicondylectomy for the treatment of cubital tunnel syndrome, rather than anterior subcutaneous transposition.

As a surgical treatment of ulnar nerve entrapment syndrome includes simple decompression, medial epicondylectomy, and anterior transposition of the ulnar nerve into a subcutaneous or submuscular bed have been widely used. Despite many reports of these surgical procedure, there is little to guide the choice of one surgical technique. The purpose of our study is to analyse clinical and electrodiagnostic result after minimal invasive decompression by decompression and medial epicondyloplasty(deepening of ulnar groove). We have experienced 9 cases of ulnar nerve entrapment syndrome who were treated with decompression and medial epicondyloplasty. Male were five and female were four. The mean age at operation was 36 years ranging from 23 to 47 years. Operative procedure was to incise the medial intermuscular septum and aponeurotic arch of flexor carpiulnaris and to deepen the ulnar groove. Patients are allowed to do range of motion(ROM) exercise on the average 5days. All patient were relieved pain and improved motor and sensory function, and this procedure allows early ROM exercise after operation because the muscle have not been detached.
