Abstract
Objective To explore the efficacy of unilateral laminotomy for bilateral decompression(ULBD)under unilateral biportal endoscopy(UBE)in treating multi-segmental central lumbar spinal stenosis(LSS).Methods This was a regression analysis.A total of 64 patients with multi-segmental central LSS admitted to Zibo 148 Hospital from June 2022 to June 2024 were selected as research subjects and were divided into the study group(n=29,ULBD)and control group(n=35,posterior lumbar interbody fusion[PLIF])according to treatment methods.The general information,perioperative indicators,preoperative and postoperative waist and leg pain,lumbar spine dysfunction,treatment effects and surgical complications were compared.Results The operation time,postoperative off-bed time and hospitalization time were significantly shorter in the study group than those in the control group.At the same time,the intraoperative blood loss was less and the incision length was shorter(P<0.05).There was no significant difference in the Visual Analogue Scale(VAS)scores of waist and leg pain between the two groups before surgery(P>0.05).Compared with preoperative values,the VAS scores of waist and leg pain in both groups were significantly reduced after surgery,which were significantly lower in the study group than the control group(P<0.05).There were no significant differences in the preoperative Oswestry Disability Index(ODI)score and Japanese Orthopedic Association(JOA)score between the two groups(P>0.05).However,the ODI and JOA scores of both groups significantly decreased after surgery,which were significantly lower in the study group than the control group(P<0.05).The total incidence rate of surgical complications in the study group(3.45%)was lower than that in the control group(17.14%),but the difference was not statistically significant(P>0.05).Conclusion For patients with multi-segmental central LSS,ULBD with UBE technology has better clinical efficacy,less bleeding,and shorter operation time.At the same time,it causes superior improvements in the postoperative pain,and lumbar spine disorder,faster postoperative recovery and less complications.关键词
