Abstract
Anterior transposition and/or medial epicondylectomy are often considered procedures of choice for ulnar neuropathy at the elbow. Much experience suggests simple decompression to be a comparably effective alternative which involves less trauma, morbidity, and rehabilitation time. The post-operative clinical and electrophysiological results of 52 cases of simple decompression (41 patients) are summarized. Excellent or good clinical results were found in 75% of the nerves. Mean ulnar motor conduction velocities were significantly improved post-operatively, although nerve conduction parameters did not consistently correlate with clinical outcome. The average return-to-work time was 5.1 weeks. The advantages of simple decompression make it the procedure of choice for most cases of ulnar neuropathy.
