Analysis of Single Decompression Combined with Discectomy,Posterior Intervertebral Body Fusion and Pedicle Screw Fixation in the Treatment of Prolapse of Lumbar Intervertebral Disc
Abstract： Objective:To evaluate the curative effect of single decompression combined with discectomy,posterior intervertebral body fusion and pedicle screw fixation in the treatment of prolapse of lumbar intervertebral disc.Methods:Twenty-three patients with prolapse of lumbar intervertebral disc were received comprehensive treatment of decompression,discectomy,posterior intervertebral body fusion and pedicle screw fixation,and followed up.In the study patients, 20 cases was 1-spinal cord (L4-5 or L5-S1),and 3 were 2-spinal cord (L4-5 or L5-S1).On the basis of the area of lumbar intervertebral disc,there were 2 central, 8 para-central,10 lateral and 3 far-lateral types cases in all patients.After operation,all patients were followed up from 8 to 16 months to perform the visual analogue scale(VAS),evaluate the oswestry disability index(ODl) and to examine the relative distance of intervertebral space(R).Notably,the interbody fusion status of each case was specially observed.Results:The statistical data revealed that the values of VAS,ODI and R were respectively 8.8±0.5,(53.25±9.35)%, 0.180±0.050 before operation.Six months following operation,the three periodontal index were respectively 1.9±0.6,(19.26±5.50)%,0.326±0.038,significantly improved relative to preoperation (P<0.05).One year after operation,the rate of fusion was 100%,without fixture rupturing or loosing.Conclusion:Combined treatment of prolapse of lumbar intervertebral disc with decompression,discectomy,posterior intervertebral body fusion and pedicle screw fixation can get satisfactory clinical outcome.
