主 题：minimally invasive lumbar discectomy automatic nerve retractor microendoscopic discectomy nerve hook
摘 要：This study compares the safety and efficiency of two techniques in microendoscopic discectomy(MED)for lumbar disc *** two techniques are MED with automatic nerve retractor and MED with nerve hook which had been widely used for many *** former involves a newly developed MED device which contains three parts to protect nerve roots during *** hundred and twenty-eight patients underwent MED treatments between October 2010 and September 2015 were recruited and randomized to either intraoperative utilization of automatic nerve retractor(n紏315,group A)or application of nerve hook during surgery(n=113,group B).Operation time and intraoperative bleeding volume were ***,Visual Analogue Scales(VAS)and muscle strength grading were performed preoperatively,and 1,2,3 days,1,2 weeks,3 and 6 months *** dramatic difference of pain intensity was observed between the two groups before surgery and 6 months after surgery(P0.05).The operation time was shorter in group A(30.3061.89 min)than that in group B(59.4163.25 min).Group A(67.83613.14 ml)experienced a significant decrease in the amount of blood loss volume when compared with group B(100.04615.10 ml).There were remarkable differences of VAS score and muscle strength grading after postoperative 1,2,3 days,1,2 weeks and 3 months between both groups(P≤0.05).MED with automatic nerve retractor effectively shortened operation time,decreased the amount of bleeding,down-regulated the incidence of nerve traction injury.
