title: [Medio-cubital anastomosis in the forearm (author's transl)].
abstract: Communication between median and ulnar nerves in the forearm may occur in at least 15% of the population. Electromyography with nerve stimulation is the method necessary for the diagnosis. Four cases with the anatomical feature are reported. The authors insist on electromyographic criteria to distinguish this anomaly from communication between the two nerves in the hand or partial or complete overlap or replacement of the motor field of one nerve by the other. The clinical and pathophysiological consequences of the MARTIN-GRUBER anastomosis are discussed.
