Abstract: Objective To compare the curative effects of lumbar traction in supine position with hip flection and extension for prolapse of lumbar intervertebral disc (PLID).Methods 84 PLID patients were all treated by lumbar traction in supine position. But, group A (42 cases) with hip flection and group B (42 cases) with hip extension. Before and after three weeks therapy, all patients were assessed by Fairbank JC index and Visual Analogue Scales (VAS) to observe the symptom and pain condition.Results The scores of Fairbank JC index and VAS scale of the patients in group A were significantly lower than those in the group B (P<0.001).Conclusion Lumbar traction in supine position with hip flection for the PLID can obviously promote the curative effects.

Key words: prolapse of lumbar intervertebral disc, traction, hip flection, hip extension
