Abstract：Objective To investigate the effects of lumbar posterior microscopically minimally invasive surgery on the pain and lumbar stability in patients with lumbar intervertebral disc protrusion.Methods A total of 140 patients with lumbar intervertebral disc protrusion who were treated in our hospital were enrolled in the study. According to random number table, these patients were divided into the minimally invasive group and traditional surgery group,with 70 patients in each group.The patients in minimally invasive group were treated by lumbar posterior microscopically minimally invasive surgery,however,the patients in traditional surgery group were treated by nucleus pulposus excision via open window between lamina of vertebra.The therapeutic effects were evaluated by means of Japanese orthopaedic association (JOA) lumbar score,and patient's pain degree was assessed by visual analogue scale (VAS),moreover,all the patients were followed up for 6 months,then the operation duration,intraoperative hemorrhage volume,length of staying in hospital,recovery work time,time of returning to work,lumbar spinal stability before and after treatment (lumbar Cobb angle,lumbar curvature index,intervertebral level displacement and angular displacement),the therapeutic effects on 3,6 months after treatment, pain degree before treatment and on 1,3,6 months after treatment,the incidence rates of complications were observed and compared between two groups. Results The operation duration, intraoperative hemorrhage volume,length of staying in hospital,recovery work time in minimally invasive group were significantly lower than those in traditional surgery group (P<0.05), however,there were no significant differences in return to original position rates between two groups(P>0.05). The lumbar Cobb angle,intervertebral level displacement and angular displacement in minimally invasive group were significantly lower than those in traditional surgery group,and the lumbar curvature indexes in the former were significantly higher than those in the latter(P<0.05). There were no significant differences in the excellence rates on 3 months after treatment and JOA scores between minimally invasive group and traditional surgery group (P>0.05),however, the excellence rates on 6 months after treatment and JOA scores in the former were significantly higher than those in the latter (P <0.05).The VAS scores on 1,3,6 months after treatment in minimally invasive group were significantly lower than those in traditional surgery group (P<0.05).The incidence rates of complication in minimally invasive group were significantly lower than those in traditional surgery group (P<0.05). Conclusion The lumbar posterior microscopically minimally invasive surgery can effectively decrease the intraoperative trauma of patients with lumbar disc prolapse and can promote postoperative recovery,which can effectively maintain the stability of lumbar spine,however, which has no obvious effects on return to original position rate of patients and on short-term curative effects,but which can alleviate the symptoms of pain and can effectively improve long-term curative effects,with better safety,therefor,which is worth using widely in clinical practice.
