Retrospective analysis of 48 medial epicondylectomy procedures in 46 patients demonstrated that symptomatic and objective improvement was usual. Most patients experienced improvement of symptoms (98%) and moving two-point discrimination (87%), and many demonstrated improved motor strength (54%). By use of the McGowan scheme for grading ulnar neuropathy, 92% of the patients with grade I neuropathy had a return to normal function. Subdividing patients with grade II neuropathy into grade IIA and IIB on the basis of the extent of motor compromise was useful in predicting postoperative outcome. Forty-five percent of the patients with grade IIA neuropathy had a return to normal ulnar nerve function and only 11% (one patient) in the IIB group had a full recovery. In the group with grade III neuropathy, one patient had improvement to grade II level and the other five remained grade III. No patient in this study demonstrated deterioration of his McGown grade. Medial epicondylectomy is a safe and predictable procedure for the treatment of symptomatic cubital tunnel syndrome.
