Observation on the clinical effect of intervertebral foramen and lumbar interbody fusion assistedby spinal minimally invasive channel endoscopy system in the treatment of lumbar de-generative diseases
Objective To investigate the effects of transforaminal lumbar interbody fusion(TLIF)assisted by spinal minimally invasive channel mirror system on spinal cord function as well as serum levels of substance P(SP)and prostaglandin E2(PGE2)in patients with lumbar degenerative diseases.Methods Fifty-one patients with lumbar degenerative diseases were selected.They were divided into group A(n=25)and B(n=26)according to the odd-even number method of admission order.The group B was treated with conventional TLIF,and the group A was treated with TLIF assisted with spinal minimally invasive channel mirror system.The surgical indexes,lumbar and leg pain and dysfunction,spinal cord function,serum SP and PGE2 levels were compared between the two groups.Results The intraoperative blood loss and postoperative drainage volume of the group A were less than those of the group B,and the time of getting out of bed of the group A was shorter than that of the B group(P<0.05).Lumbar Visual Ana-logue Scale(VAS)and Oswestry Disability Index(ODI)scores of both groups were significantly improved after 4 weeks of surgery(P<0.05).The indexes of spinal cord function in both groups were significantly improved after 7 days of operation,and the improvement in the group A was better than that in the group B(all P<0.05).The serum SP level of the group A was higher than that of the group B,but the serum PGE2 level of the group A was lower than that of the group B(all P<0.05).Conclusions TLIF assisted by minimally invasive spinal channel endoscopic system can significantly improve the spinal cord function and pain mediators in patients with lumbar degenerative diseases.
