Recurrent lumbar disc herniation after discectomy alone:long-term results / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the long-term results of recurrent lumbar disc herniation between different kinds of reoperation.[Method]Seventy-four patients of recurrent lumbar disc herniation after discectomy alone were treated surgically from May 2001 to Augest 2005.They were divided into three groupsnonfusion,posterolateral fusion and intervertebral fusion.After a long term follow-up(≥2y),their clinical data were reviewed to compared their improvement rate of lower back pain,JOA score,subside rate of disc height and chang rate of superior intervertebral space angle.[Result]The long-term results revealed that the improvement rates of lower back pain JOA score in the three groups were increased in sequence.The differences in subside rate of disc height and change rate of superior intervertebral space angle between discectomy and posterolateral fusion groups were insignificant,but much higher than those of posterior lumbar interbody fusion group.[Conclusion]Posterior lumbar interbody fusion is effective in increasing the improvement rates of lower back pain JOA score and maintaining the disc height and the superior intervertebral space angle.
