Abstract:
Objective To investigate the effects of the relationship between bone cement polymethyl methacrylate (PMMA) and endplate on the vertebral height loss after percutaneous vertebroplasty (PVP).Methods A retrospective analysis of 84 female patients with single segment osteoportic vertebral compression fracture who had undergone PVP between Jun.,2013 and May,2016 was conducted.According to the X-ray radiographs and CT scans,all subjects were divided into the doPMMA-endplate-contact group (40 cases,average age 76.88 years) and the non-PMMA-endplatecontact group (44 cases,average age 77.96 years).The volume of bone cement,operation time,fractured vertebral height restoration rate,3-month postoperative vertebral height loss rate,changes in local sagitta view Cobb angle and bone cement leakage rate were respectively recorded and compared.Results There were no significant difference in age,body mass index,the levels of serum calcium and phosphorus,bone mineral density and preoperative vertebral body compression rate between the two groups (P＞0.05).Postoperative vertebral height loss rate and changes in local sagitta view Cobb angle in the do-PMMA-endplate-contact group were significantly less than the non-PMMA-endplate-contact group (P＜0.05).However,there was no significant difference in bone cement leakage rate between the two groups (P＞0.05).Conclusions Making bone cement contact with endplate would reduce the height loss of cemented vertebrae without increasing the rate of cement leakage.
