title: Clinical and electrophysiological investigation of the results of operation for lumbar disc hernia. Preliminary results.
abstract: The long-term results of operations to remove disc hernias were assessed clinically and electrophysiologically in two groups of patients treated by different surgical techniques. The electrophysiological parameters determined were the motor conduction speed of the sciatic nerve, the H reflex, the minimum latency of the F wave and quantitative analysis of the EMG by the Willison method. The preliminary results reported in the present paper are related to two comparable samples of patients who underwent hemilaminoarthrectomy or hemilaminectomy for disc hernia at L5-S1. They show that the incidence of after effects was lower in the patients treated by simple hemilaminectomy.
