[Compression of the ulnar nerve near the elbow].

The ulnar nerve is subject to an entrapment neuropathy at the elbow. The groove behind the medial epicondyle is by the adjacent structures transformed to a tunnel. This passage is the most significant entrapment point of nerve. Duurgery we treated 18 patients with the entrapment ulnar neuropathy at the elbow. Operative decompression had been performed and when necessary, anterior transposition and neurolysis under the microscope control. After the operation some of the patients had complete relief of symptoms. Lifelong cases had partly ameliorated. Three patients are described in details. In our paper we appeared the mechanism and diagnosis of cubital tunnel compression, It is pointed that early diagnosis and operative treatment are only preferable in healing the ulnar entrapment neuropathy at the elbow.
