Comparison Of Clinical Efficacy Between OLIF(Stand-alone) And PLIF In The Treatment Of Lumbar Degenerative Diseases

Objective: To investigate the clinical effect of OLIF Stand alone and PLIF in the treatment of degenerative diseases of the lumbar spine.Method: Retrospective analysis and summary were performed on 78 cases of lumbar degenerative diseases treated with OLIF(Stand alone)and PLIF(38 cases in the OLIF group)in the yijishan hospital of wannan medical college from April 2016 to October 2018,respectively.By comparing the intraoperative blood loss,postoperative length of stay,operation time and surgical complications of the two groups,Measure intervertebral disc height before and after surgery(interverebral disc height,IDH),height of intervertebral foramen(intervertebral foramen height,IFH),intervertebral foramen area,intervertebral foramen area(IFA),surgical segmental lordosis cobb Angle,intervertebral bone graft fusion,Oswestry disability index(ODI)and Visual analogscale(VAS)were used to evaluate the surgical efficacy.Results: OLIF group of postoperative hospitalization days(3.13 ? 0.34)d,intraoperative blood loss(48.15 ? 5.15)mL,operation time(80.50 ? 9.52)min,PLIF group of postoperative hospitalization days(7.95 ? 1.32)d,intraoperative blood loss(159.21?21.57)mL operation time(167.76?20.46)min,the difference between the twogroups was statistically significant(P<0.05),in terms of VAS,two groups were significantly better than that of preoperative patients of postoperative follow-up situation,differences between the two groups,VAS score before surgery,VAS score at 3months after surgery,and VAS score at the last follow-up had no statistical significance(P>0.05),while VAS score at 1 month after surgery had statistical significance(P<0.05).In terms of ODI,there was no statistically significant difference between the two groups before and at the last follow-up(P>0.05),and there was a statistically significant difference between the two groups 1 month and 3 months after the surgery(P<0.05).In intervertebral height,height of intervertebral foramen,intervertebral foramen area,surgery segmental lordosis Angle,the two groups were obviously improved compared with before operation,preoperative intervertebral height,height of intervertebral foramen,intervertebral foramen area,segmental lordosis Angle operation there was no statistically significant difference between the two groups(P>0.05),postoperative height of intervertebral foramen,intervertebral foramen area,surgery segmental lordosis Angle difference between the two groups was statistically significant(P<0.05).PLIF group has 3 cases of postoperative epidural cyst rupture,cerebrospinal fluid leakage,3cases of postoperative PLIF group appear incision inflammation,postoperative 3months review plain film in OLIF and PLIF group respectively in 3 cases and 1 case of Cage subsidence Ⅱ degrees.During the follow-up 3 months after the operation,the two groups of patients were found to have bony fusion in the intervertebral space by imaging examination,and no cage displacement,internal fixation failure and other complications occurred.Conclusion: Both OLIF and PLIF are practical and feasible surgical methods for the treatment of lumbar degenerative diseases.However,OLIF has shorter postoperative hospital stay,less intraoperative bleeding,less surgical trauma,does not damage the rear stable structure,and reduces intraoperative dural sac The advantages of injury and intraoperative nerve root traction injury are more in line with modern minimallyinvasive concepts.However,the indications for surgery should be strictly controlled and the most appropriate surgical method should be selected.
