Abstract/Text
We have performed minimal medial epicondylectomy for cubital tunnel syndrome since 1990 to preserve the anterior medial collateral ligament. In this study we compared surgical outcomes between partial medial epicondylectomy (14 patients) and minimal medial epicondylectomy (18 patients) combined with ulnar nerve decompression for the treatment of cubital tunnel syndrome. Mean preoperative Yasutake scores were 57 +/- 17 points (+/-SD) in the partial epicondylectomy group and 60 +/- 15 points in the minimal medial epicondylectomy group. The postoperative scores were 79 +/- 19 points and 87 +/- 10 points, respectively. Both groups had significant improvement in their Yasutake scores following medial epicondylectomy. Similar improvements in motor conduction velocity were observed. There was no significant difference in improvement of either the Yasutake scores or the motor conduction velocity between the 2 groups. Valgus instability of the elbow was significantly greater in the partial epicondylectomy group. We therefore conclude that minimal medial epicondylectomy combined with ulnar nerve decompression is an effective treatment for cubital tunnel syndrome and that a larger excision of the medial epicondyle should be avoided.
