[Anterior interosseus nerve syndrome (Kiloh-Nevin) (author's transl)].

The Authors describe two cases of "Anterior interosseus nerve syndrome" with spontaneous recovery. The etiopathogenesis of the syndrome is discussed after reviewing the anatomy of the nerve and muscles, as well as diagnostic procedures. The main clinical features are: 1) no sensory troubles, 2) impairment of muscles innervated by interosseus nerve (flexor pollicis longus, external portion of flexor digitorum profundus, pronator quadratus). The electrophysiological confirmation of the diagnosis is based on EMG findings, while conduction velocity appears to be complementary but not conclusive. The therapeutic aspects are discussed.
