A Study of Tardy Ulnar Neuritis

Abstract

A clinical and electro-diagnostic examination was made in thirty-two cases of tardy ulnar neuritis, and the result of medical treatment was investigated in twenty-six cases after surgery.
On the other hand, using the experimental constricting sciatic nerves of rabbits, the authors made a scanning electron microscopic study of the mechanism of paralysis of tardy ulnar neuritis and related syndromes.
Above mentioned studies lead to the following conclusion:
If paralysis is long-standing and serious, decompression fails to relieve the symptoms completely. Thereby, in the early stage of compression, surgical decompression such as division of the band of fibrous tissue bridging the two heads of M. flexor carpi ulnaris (so-called neurolysis) or excision of the medial epicondyle becomes mandatory.
