IntroductionThe medial epicondyle behaves as a fulcrum and a pulley that tethers the ulnar nerve during flexion. Excision of the distal half of the medial epicondyle sets the point of contact of the bone with the nerve proximally and decreases the traction effect of the medial epicondyle on the ulnar nerve. In this study, we aim to investigate the surgical and clinical results of excision of the distal half of the medial epicondyle in cubital tunnel syndrome (CuTS).Patients And MethodsCubital tunnel release with excision of the distal half of the medial epicondyle was performed in 19 patients. The patients were evaluated preoperatively and postoperatively with clinical examinations, McGowan and Wilson-Krout scores, Semmes-Weinstein monofilament and two-point discrimination tests, and grip and pinch strength measurements.ResultsA one-grade improvement in McGowan classification was observed in 79 % of patients and a two-grade improvement in 21 % of patients at the time of the first postoperative examination. At 24 months after surgery, 18 patients reported the Wilson-Krout scores as excellent (95 %). Statistically significant improvements in sensory and motor strength measurements were achieved at all postoperative examinations.ConclusionThe objective and subjective outcome measures achieved with distal medial epicondylectomy are comparable with other epicondylectomy techniques. The complication rates seem to be lower than those of total or partial medial epicondylectomy. This procedure is an acceptable and safe alternative for the surgical treatment of CuTS.
