Abstract：Objective To investigate the curative effect of microscopic lumbar discectomy (MLD) with the tubular retractor system on lumbar disc herniation (LDH). Methods Of 156 patients with LDH undergoing surgery from June 2014, to June, 2016, 96 underwent MLD with the rubular retractor system (treatment group) and 60 underwent open lumbar discectomy (control group). All the patients were followed up for 1 year. Results The scores of mean Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) and the good rate of MacNab function were significantly better 1 year after the operation than those before the operation in both groups (P<0.05). The VAS and ODI scores were significantly lower in the treatment group than those in control group 1 week and 3 months after the operation (P<0.05). There were insignificant differences in the scores of VAS and ODI between both the group 1 year after the operation (P>0.05). The volume of intraoperative lost blood and days of hospital stay were significantly less in the treatment group than those in control group (P<0.05). Conclusion MLD with tubular retractor system is of many the advantages including minimally invasive, better curative effect, quicker postoperative recovery, and shorter hospital stays compared to the open lumbar discectomy in the patients with LDH and therefore it is worth spread.
