Comparison Of The Effects Of Vesselplasty And Percutaneous Kyphoplasty For The Short-term Efficacy Of Osteoporotic Vertebral Compression Fractures With Posterior Wall Deficiency

Objective:To evaluate the short-term clinical efficacy of vesselplasty and percutaneous kyphoplasty(PKP)in the treatment of osteoporotic vertebral compression fractures(OVCF)with posterior wall deficiency.Methods:42 patients with vertebral compression fractures due to osteoporosis were treated with Vesselplasty or PKP in our hospital from January 2014 to August 2017 were enrolled in the study.Among them,15cases were the former and 27 cases were in the latter.The postoperative cement leakage was observed in the two groups,and the visual analogue scale(VAS),Oswestry disability index(ODI),Cobb angle of the injured vertebrae,height of the injured vertebral body were recorded before and 1st day after surgery.Results:The leakage rate of bone cement in the Vesselplasty group was 57.1%(8/14),of which 6 cases were non-back wall leakage and 2cases were posterior wall leakage.The cement leakage rate of PKP group was 65.4%(17/26),of which 12 cases were non-the posterior wall cement leaked,and 5 cases of the posterior wall of the vertebral body leaked.There was no significant difference in bone cement leakage rate between the two groups(?~2=0.264,P=0.608).The VAS scores,ODI were both significantly improved 1st day after surgery.Cobb angle was significantly reduced in both groups 1st day after surgery.The anterior,middle and posterior height ratio of injured vertebra were significantly increased 1st day after surgery,and there were statistically significant differences in the two groups before and after surgery(P<0.05).But the difference between the groups was no significant differences(P>0.05).Conclusion:Patients with posterior wall deficiency OVCF were treated with Vesselplasty or PKP was no significant difference between the relief of thoracolumbar pain,the improvement of their living quality,the recovery of Cobb angle of the injured vertebrae and the height of the injured vertebrae,however,the above indexes of the two groups were significantly improved compared with the preoperative.And there was no significant difference in the cement leakage rate between the two groups,and the safety of clinical application was similar.
