[Clinical aspects and neurophysiology of distal ulnar nerve paralysis]

The clinical and neurophysiological findings of 26 patients with distal lesions of the ulnar nerve area presented in relation to their etiology. A useful procedure for the neurophysiological examination of patients with suspected ulnar nerve lesion is described and the great value of sensory neurography for the localisation of lesion as well as for postoperative control is emphasized. A classification of distal ulnar nerve lesions in four types according to locus of lesion is proposed.
