Clinical Analysis Of BEIS Technique And FD In Treating Severe Free Prolapse LDH Based On The Theory Of "Equal Emphasis On Bones And Bones"

Objective: 1.Study the clinical effect of intervertebral foramen BEIS technique in treating severe free prolapse lumbar disc herniation.2.Compare the clinical efficacy of intervertebral foramen BEIS technique and interlaminar fenestration in the treatment of severe free prolapse lumbar disc herniation based on the theory of "equal emphasis on muscles and bones",and provide reliable ideas for the treatment of severe free prolapse lumbar disc herniation in the future.Methods: 62 patients with severe free prolapse lumbar disc herniation treated by orthopedic surgery in the affiliated hospital of Shandong University of Traditional Chinese Medicine from January 2018 to August 2019 were selected for retrospective analysis.According to the different operation methods,they were divided into poroscopy group(BEIS group)and fenestration group,of which 32 n= poroscopy group and 30 n= window opening group.To compare and analyze the basic information of patients before operation,record the operation time,incision length,intraoperative bleeding volume,intraoperative medullary nuclear removal volume,intraoperative bone removal,postoperative time out of bed,postoperative hospitalization time,and so on.Monthly VAS score(total 10 points),6 months after operation ODI score and the modified Mac Nab score for the last follow-up.By collecting the above data information,using SPSS Statistics 26.0 statistical software to carry out statistical analysis of the data,the clinical conclusions are drawn.Results:1.Operation related information: operation time,incision length,intraoperative bleeding volume,intraoperative nucleus pulposus removal,intraoperative bone removal,postoperative time out of bed,postoperative hospitalization time,P<0.05,the difference was statistically significant.2.VAS score: the preoperative VAS scores of the two groups were compared with1 day,1 week,1 month,3 months and 6 months after operation,p<0.05,the difference was statistically significant.The VAS scores were compared between the two groups at each time point after operation,p<0.05,the difference was statistically significant.3.ODI score: the postoperative ODI score of the two groups was significantly lower than that before operation,P<0.05,which was statistically significant.Preoperative and postoperative ODI scores P>0.05 between the two groups,the difference was not statistically significant.4.Improved Mac Nab score: the excellent and good rate in BEIS group was 87.50%.The excellent and good rate of the window opening group was 90.00%.Excellent and good rate ratio P>0.05 between the two groups,the difference was not statistically significant.Conclusion:1.Intervertebral foramen BEIS technique for the treatment of severe free prolapse lumbar disc herniation clinical efficacy is satisfactory.2.On the basis of the theory of "equal emphasis on bones and bones ",there is no statistical difference in the clinical effect of intervertebral foramen BEIS technique and interlaminar fenestration in the treatment of severe free prolapse lumbar disc herniation,but the intervertebral foramen BEIS technique is more minimally invasive in clinical application and more acceptable to patients.3.Intervertebral foramen BEIS technique in the clinical treatment of severe free prolapse lumbar disc herniation,the operation time is often longer than the laminotomy,which is proportional to the difficulty coefficient of the operation,which is also an important reason to limit its clinical application.4.The operation mode should be determined according to the patient’s psychological acceptance,image examination and the doctor’s operation experience.It should not be blindly minimally invasive.
