Objective To investigate the efficacy of unilateral biportal endoscopy(UBE)technique in treatment of lumbar spinal stenosis(LSS).Methods UBE technique was used to treat 30 patients with LSS.The observation indi-cators:the postoperative hospitalization time,occurrence of complications,VAS of back and leg pain,and ODI score.The efficacy was evaluated by using MacNab score.Results The patients were all followed up for 6～24 months.The postoperative hospitalization time was 3～13(6.17±2.44)d.Except for 1 case with symptoms of cauda equina inju-ry,the remaining 29 cases had no postoperative complications such as nerve injury,dural sac tear,cerebrospinal fluid leakage,intraspinal hematoma,incision infection,etc.VAS of lower back and leg pain,ODI scores:postoperative vari-ous time periods were lower than the preoperation(P＜0.05);all indicators became better and better with the time prolonging(P＜0.05).At the last follow-up,the MacNab score was used to evaluate the efficacy,20 cases were excel-lent,8 cases were good,1 case fair,and 1 case poor.The excellent-good rate was 28/30.Conclusions UBE tech-nique can treat LSS with both unilateral and bilateral decompression,as well as endoscopic fusion,and which has min-imal damage to spinal stability.Patients have a good postoperative recovery and satisfactory therapeutic effect.
