Abstract

Although compression of the ulnar nerve is a common condition, many controversies remain in its management. Compression of the ulnar nerve around the elbow, cubital tunnel syndrome, is most common. This chapter reviews the relevant anatomy and the pathophysiology of ulnar nerve entrapment. Diagnosis depends on clinical examination and neurophysiology tests. Non-operative management includes activity modification and splintage. Surgery is recommended for patients with persisting symptoms. In situ decompression of the ulnar is adequate in most cases, with anterior transposition being reserved for recurrent symptoms. The ulnar nerve may also be compressed at the wrist requiring surgical decompression.
