[Conductivity of the radial nerve following its injury].

Evoked muscle potentials are usually lacking in cases of complete anatomical interruption of the radial nerve. With all other data considered, such patients are subject to surgery. In cases when evoked muscle potentials are recorded in the presence of neurological signs of a complete interruption of the nerve, its anatomical continuity is usually retained. In such patients the velocity of conduction falls to 6.37 +/- 1.9 (sigma4) m/sec. In such patients non-sucrgial treatment results in the appearance of active fingers extension and sensations improvement.
