Sulcus ulnaris Syndrom nach Traumen im Ellenbogenbereich

Abstract

For a large scaled test 52 patients with anterior transposition of the ulnar nerve and 62 patients with elbow injuries were examined by questionnaire, physical examination and electroneurography. In conformity with existing literature 24 patients out of 52 suffering from cubital tunnel syndrome had an elbow trauma previously. To our great surprise in seven patients out of 46 with elbow injuries a cubital tunnel syndrome could be found for the first time. The cubital tunnel syndrome appears to be a frequent complication of elbow injuries. Besides the well known fractures of the medial epicondyle and pericondylar fractures leading to cubital tunnel syndrome, in our study fractures of the head of the radius and processus coronoideus were found quite often. Patients having typical anamnesis and complaints should be checked by electroneurography in order to permit a quick operation and to prevent incurable damages of the nerve. The diagnosis leading to operation of the elbow should however be made with greatest care. In case the operation is unavoidable, the ulnar nerve should be thoroughly checked and anterior transposition should be carried out.
