Comparison of effects of percutaneous kyphoplasty and percutaneous vertebroplasty in treatment of elderly patients with osteoporotic vertebral compression fractures
Objective:To compare effects of percutaneous kyphoplasty(PKP)and percutaneous vertebroplasty(PVP)in treatment of elderly patients with osteoporotic vertebral compression fractures(OVCF).Methods:The clinical data of 60 elderly patients with OVCF admitted to this hospital from February 2021 to February 2023 were retrospectively analyzed.According to different surgical methods,they were divided into study group and control group,30 cases in each group.The control group was treated with PVP,while the study group was treated with PKP.The operation related indexes(operation time,intraoperative blood loss,intraoperative X-ray irradiation times,bone cement dosage)levels,the spinal structure indexes(Cobb angle,anterior vertebral height and vertebral compression rate)levels,the lumbar function[Oswestry dysfunction index(ODI)]score before and after the surgery,and the incidence of complications were compared between the two groups.Results:There were no significant differences in the operation time and the intraoperative blood loss between the two groups(P>0.05).The intraoperative X-ray irradiation times in the study group was less than that in the control group,the bone cement dosage was more than that in the control group,and the differences were statistically significant(P<0.05).Seven days after the surgery,the Cobb angle levels of the two groups were smaller than those before the surgery,and that of the study group was smaller than that of the control group the vertebral compression rates of the two groups were lower than those before the surgery,and that of the study group was than that of the control group;the anterior vertebral height of the injured vertebrae of the two groups were higher than those before the surgery,and that of the study group was higher than that of the control group;and the differences were statistically significant(P<0.05).Three months after surgery,the ODI scores of both groups were lower than those before surgery,and the ODI score in the study group was lower than that in the control group,and the differences were statistically significant(P<0.05).Further,the incidence of complications in the study group was 6.67%(2/30),which was lower than 26.67%(8/30)in the control group,and the difference was statistically significant(P<0.05).Conclusions:Compared with PVP,the PKP in the treatment of the elderly patients with OVCF can reduce the intraoperative X-ray irradiation times,increase the bone cement dosage and the anterior vertebral height of the injured vertebra,reduce the postoperative Cobb angle,the vertebral compression rate,ODI scores and the incidence of complications,and do not increase the operation time and the intraoperative blood loss.
