Comparison Of Two Kinds Of Surgical Treatment For Degenerative Lumbar Spondylolisthesis

ObjectiveComparative analysis of two surgical treatments for degenerative spondylolisthesis.MethodFrom January 1,2014 to December 31,2014 56 to collect and analyze the senile mild lumbar spondylolisthesis during bone surgery of First Affiliated Hospital of Xinxiang Medical College hospitalized cases,respectively using TLIF and open TLIF minimally invasive surgery,minimally invasive surgical method of TLIF,which is in the Quadrant system to guide,look for cone,nerve root and spinal canal decompression,unstable vertebral pedicle bone graft fusion.The three column fixation scre w.Minimally invasive TLIF s urgery was performe d in 26 patients and open TLIF surgery in 30 patients.According to intraoperative incision length(CM),operation time(min),the amount of bleeding during and after surgery(ML),total length of stay(d)data such as statistical simulation method;score and JOA score by visual symptoms before surgery,the degree of improvement of symptoms were compared with patients the postoperative period,divided into three days,two week,March,half a year,statistical analysis;observation of patients with preoperative and postope rative 1 weeks,half year and 1 year by the measure ment of vertebral sli p angle,slip rate correction,distraction intervertebral height recovery,postoperative follow-up shot afte r operation the first half of 1 years,CT and X-ray assessment of interbody bone fusion rate by the same doctor of vice director of image.ResultMinimally invasive group TLIF,26 cases of the first half of all patients followe d up,4 patients in the postoperative 1 years lost;and in the open surge ry group,5 patients were lost to follow-up,the dropout rate was 16%;the follow-up time span for 6-30 months,average 19 months.Comparative analysis of two groups of postope rative wound length,total amount of bleeding,hospitalization days,minimally invasive group than in the open group,statistical differences,this study we re performe d by skilled senior physicians in the ope ration,operation time is short compared to the overall open surgery group,but P is more than 0.05,the statistical difference is not significant.Through the analysis of postoperative symptoms,the VAS,JOA score and ODI of the patients all reflected the symptoms alleviated,and the operation effect was good.There was significant difference in statistical calculation(P<0.05).Similarly,afte r the analysis of symptoms in March,the VAS,JOA score and ODI of the patients all showed obvious symptoms,and the operation effect was good.There was significant difference in statistical calculation(P<0.05).Postoperative imaging data show that two groups of lumbar slip angle and intervertebral disc height and slippage rate were significa ntly corrected before and after surgery we re significant differences,but there was no diffe rence between the two groups.Fusion analysis of minimally invasive surgery group after the June rate of imaging(Suk)reached 88.5%,6 months after fusion rate of minimally invasive group TLIF 23 cases(88.5%),TLIF group of 14 cases(46.7%),two groups of 1 years after the fusion rate of minimally invasive group TLIF 20 cases(4 cases(76.9%)Note: 1 years after surgery,minimally invasive TLIF group of 26 patients,5 cases lost)may open fusion;23 cases in group TLIF(76.7%)(Note: 1 years after the ope ration,the open TLIF group of 30 patients,5 cases were lost),3 cases of possible fusion;compared with the open group,the minimally invasive group 6 months afte r the operation showe d a higher fusion rate,but no statistically significant difference,P>0.05.ConclusionMinimally invasive TLIF surge ry and open TLIF surge ry compared with surgery to reduce the amount of bleeding,shorten the hospitalization time,fas ter postope rative recovery,less postoperative chronic pain and postope rative lumbar syndrome,spondylolisthesis correction rate and open surgery is not the difference between fusion and intervertebral height recovery.Therefore,minimally invasive TLIF technique is an effective treatment for elderly degenerative spondylolisthesis with spinal stenosis and s pondylolisthesis.
