Dorsal cutaneous branch of ulnar nerve: an appraisal on the anatomy, injuries and application of conduction velocity studies in diagnosis

Abstract

Classical textbooks and recent publications about the anatomy of the dorsal cutaneous branch of the ulnar nerve are revisited and correlated with methods of measurement of its conduction velocity, in order to evaluate the indications and limitations of the procedure. Etiology and pathogenesis of isolated lesions of this nerve branch are discussed.
