Abstract: ［Abstract］ Objective To evaluate preliminary clinical efficacy of minimally invasive posterior lumbar spine interbody fusion under Quadrant system for lumbar disc herniation. Methods From January 2012 to December 2014, a total of 18 cases suffering from lumbar disc herniation were implemented surgery. These cases underwent interbody fusion via bilateral paramedian approach under Quadrant invasive system. ODI and VAS score was used to evaluate the pre?and post?revision operation outcome Lumbar CT scan and three?dimensional reconstruction was used to assess the lumbar interbody fusion. Results Thirty?six patients were followed up for 6?25 months（mean, 12.6 months）. The mean VAS score at preoperation was 7.31±1.6, the last follow?up after operation average VAS score was 3.15± 0.54, which showed statistical significance（P<0.05）. Preoperative averaged ODI score was 38.54±3.21, the last follow?up after operation averaged ODI score was 5.96±3.12, there are differences compared with preoperative statistical significance （P<0.05）. All cases got bony fusion in the last follow-up after operation. No breakage of pedicle screws and fusion device shift were noted. Conclusion The Quadrant channel of minimally invasive lumbar interbody fusion in the treatment of lumbar disc herniation is safe and effective.
