Efficacy Analysis Of Unilateral Biportal Endoscopic In The Treatment Of Degenerative Lumbar Spinal Diseases

Objective: To investigate the clinical efficacy of unilateral biportal endoscopic(UBE)in the treatment of degenerative lumbar spinal diseases.Methods: 83 patients(38 males and 45 females)with degenerative lumbar spinal diseases were treated with UBE in our department from August 2021 to August 2022,including 21 patients with lumbar disc herniation,42 patients with lumbar spinal stenosis,and 20 patients with degenerative lumbar spondylolisthesis.All patients underwent unilateral biportal endoscopic lumbar decompression,and unilateral laminectomy with bilateral decompression for those with bilateral radicular symptoms,endoscopic interbody fusion and percutaneous pedicle screw fixation was performed for some patients with lumbar disc herniation combined with calcification,severe stenosis with instability and spondylolisthesis.The mean operation time,intraoperative bleeding,time to ambulation,postoperative hospital stay,and complications were recorded.The Visual Analogue Scales(VAS)for pain in low back and legs and Oswestry Disability Index(ODI)at preoperative,on the day after the operation,one month,three months,and the last follow-up,as well as modified Macnab criteria was used to assess clinical efficacy.Results: All patients completed the surgery successfully.The mean operation time was(131.69±21.83)min and intraoperative bleeding was(118.55±21.65)ml.Wearing a lumbar brace to ambulation(1.70±0.69)days after the operation.The mean postoperative hospital stay was(4.28±1.10)days.The ODI,VAS leg and VAS low back scores significantly improved after operation throughout the follow-up period.According to the modified Macnab criteria,the final outcome was excellent in 69 cases,good in 11 cases and fair in 3 cases,and the excellent and good rate was 96.4%.Seven complications occurred in total,and the incidence rate was 8.4%.Conclusion: UBE is a safe and effective procedure for the treatment of degenerative lumbar spinal diseases,with good clinical efficacy and less surgical trauma and complications.
