Abstract: 【Abstract】〓Objective〓To evaluate preliminary clinical efficacy of minimally invasive posterior lumbar spine interbody fusion under Quadrant system for recurrent lumbar disc herniation. Methods From January 2010 to December 2012,.a total of 25 cases with recurrent lumbar disc herniation were implemented surgery. The patients underwent interbody fusion via bilateral paramedian approach under Quadrant invasive system. ODI and VAS score were used to evaluate the pre-and post-revision operation outcome. Lumbar CT scan and three-dimensional reconstruction were used to assess the lumbar interbody fusion. Results〓Twenty five patients were followed up for 12-36 months (mean, 19.2 months). The VAS score at preoperation was 8.26±1.4, and 2.47±0.65 at last follow-up after operation, which showed statistical significance (P<0.05). ODI score preoperative and the last follow-up after operation were 40.32+3.14 and 6.67±2.54 (P<0.05), respectively. All cases got bony fusion in the last follow-up after operation. No breakage of pedicle screws or fusion device shift was noted. Conclusions〓It is safe and effective by using the Quadrant minimally invasive system for lumbar interbody fusion in the treatment of recurrent lumbar disc herniation.
