To the Editor.— The article "Cubital Tunnel Syndrome" has several obvious flaws. The first is that no real comparison is made in a statistical sense between clinical testing and the electromyographic testing. From reading some of these descriptions, I think that many of these cases are thoracic outlet syndromes. The second objection is that treatment for ulnar nerve compression at the elbow is, I think, generally accepted to be transposition of the nerve to the anterior surface of the extremity. Dr Clark obviously does not agree with that, but he does not compare the results of his surgery with the standard procedure, nor does he actually cite any results or follow-up procedures.
