Radial nerve lesions associated with fractures of the humeral shaft

Radial nerve palsy associated with a fracture of the shaft of the humerus is a relatively common injury. Out of 91 radial nerve injuries, operated upon in the Neurosurgical University Clinic in Belgrade from 1979 to 1988, 37 were associated with fractures of the humeral shaft or their surgical treatment. These fractures were previously treated in other medical units. In all cases a microsurgical reconstruction of the radial nerve was done: an interfascicular neurolysis in 24 cases and interfascicular grafting in 13 cases. A useful functional recovery was obtained in 91.9 per cent of the cases. Timing of nerve exploration and repair, as a main problem, is discussed.
