[Contribution of electromyography to the study of ulnar nerve lesions in the hand. Compression syndrome of the motor branch of the ulnar nerve (author's transl)].

Standard electromyographic investigations: detection and stimulodetection; segmental motor nerve conduction rate, distal motor latencies (interphalangeal V and I short abductor muscles), and distal sensory (antidromic) conduction time, were used to explore seven cases of distal paralysis of the ulnar nerve. Results enabled differentiation of elective lesions of the deep motor branch from those of the ulnar nerve in Guyon's canal. These two types of lesion correspond to precise anatomical features: the channel between the pisiform and unciform bones on the one hand and Guyon's canal on the other. The electroclinical syndrome of the deep branch should be considered as a separate true canalicular syndrome. Treatment is by surgery in most cases.
