MEDIAL EPICONDYLECTOMY IN CUBITAL TUNNEL SYNDROME: AN ELECTRODIAGNOSTIC STUDY

neuropathy demonstrated an improvement in clinical symptoms. In all patients a N.C.V. study, in which compression of the uhuu nerve at the cubital tmmel was evident, has been a prerequisite for operation. Conduction velocity across the cubital tunnel averaged 48 % of normal (26.4 +/- 8.7 metres per second) preoperatively and increased to 85 % of normal (46.7 + /- 9.7 metres per second) postoperatively. A preoperative N.C.V. study allows the achievement of a high success rate, especially in the less well clinically defined group of patients with grade I neuropathy (subjective complaints without any objective signs of muscle atrophy). Medial epicondylectomy is safe and predictable in the treatment of cubital tunnel syndrome. Journal of Hand Surgery (British Volume, 1992) 17B: 255-256 Compression of the ulnar nerve in the cubital tunnel can cause pain and dysaesthesia, and may lead to motor weakness in the ulnar nerve distribution. Similar symp-toms may be caused by degeneration changes in the cervical vertebrae. The differential diagnosis is particu
