title: [The endoscopic management of the cubital tunnel syndrome--an anatomical study and first clinical results].
abstract: Besides the carpal tunnel syndrome, the cubital tunnel syndrome (CuTS) represents the second most frequent nerve entrapment syndrome. The current gold standard for surgical therapy consists of simple open decompression. Recently, an endoscopic procedure involving long-distance decompression of the ulnar nerve has been developed and this is the topic of the present study. The first part of this paper describes preliminary anatomic investigations on 22 cadaver arms. In every sample we observed a thickening of the submuscular membrane between the heads of the flexor carpi ulnaris (FCU) which surrounds the ulnar nerve. This was especially the case for the first 10 cm from the medial epicondyle In the second part we report our experiences with this endoscopic decompression procedure in 36 patients. With this endoscopic decompression we achieved good to very good results according to the Bishop classification in 28 patients (78%). On the basis of anatomic considerations and our current experience, the endoscopic procedure seems to represent a promising alternative to simple decompression.
