A Clinical Study Of Percutaneous Endoscopic "V" Zone Anatomy-guided Foraminoplasty In The Treatment Of Lumbar Spinal Stenosis

Objective This experiment introduced the clinical effect of vertebral for ato plasty under V" area,and analyzed the clinical effect of lumbar spinal stenosis(Lumbar spinal stenosis LSS),summarized the technical points,clarified the safety,feasibility and effectiveness,provided evidence support for clinical application,and laid the theoretical foundation for the clinical application.Methods Retrospectively analyzed 6 4 patients with lumbar spinal stenosis from November 2019 to July 2 0 2 0,Sex,age,surgical sections,Improve the preoperative examination and design the surgical plan,All patients underwent percutaneous endoscopic " V" anatomical anatomical guided vertebral for ato plasty,Evaluation of clinical efficacy with preoperative,pre discharge,postoperative January,March,6,and 1 2-month VAS?JOA?ODI scores,Last follow-up,Statistical number of intraoperative perspectives,Operation time,Days in hospital,Post operative complications occurred.By comparing the preoperative and postoperative review of the imaging data,Summarize the technical key points.Results A total of 64 cases have completed the follow-up,Of these,3 6males,For 28 women,Max imum age of 79 years old,Min imum age of 30 years old,A verage age(5 4.0 6 ± 1 1.5 2)years,Of which 5 5 L4-5 segments,LS-S1 segment : 4 cases,L3-4 segment : 5 cases,In the lumbar region,For 7 cases in Zone1,2a District 48 cases,2b District in 9 cases,VAS low back pain and legs before discharge,January,March,6 postoperative,and 1 year after surgery.The pain score to preoperative ratio was statistically significant(p< 0.05)and the waist and leg pain scores to preoperative,March and June(p< 0.05).The JOA score gradually increased before discharge,January,March,June,and 1 year after surgery,with the statistical difference between preoperative ratio(p< 0.05).The ODI score grade showed that at the last follow-up,the degree of dysfunction was significantly lower compared with preoperative,and the difference had statistical significance.All postoperative dysfunction in June and December was changed to mild and moderate.Macnab score:43 better,19 better,1 better,1 worse,and excellent rate of 96.88%.Conclusion 1? percutaneous endoscopy " V" forpoplasty is a new method for the treatment of lumbar lateral spinal stenosis.Its exact clinical effect can significantly improve the pain of waist and lower limbs,promote the recovery of patients ' waist and leg function after surgery,and make the daily life return to a normal state.2?This technique performs puncture,positioning,verteplasty and decompression under the guidance of surgical philosophy.It has the advantages of rapid intraoperative puncture positioning,less perspective,small radiation to the doctor-patient,and can conduct multiple and accurate formation of the joint protrusion according to the needs of decompression.Therefore,it can be fully decompression along the tip of the joint protrusion to the vertebral arch,and the forming operation is safe and short learning time,which is worth in-depth research and application.
