Clinical study of curved vertebroplasty with polymethyl methacrylate bone cement injection in the treatment of osteoporotic vertebral compression fractures
Objective:To investigate the clinical effect of curved vertebroplasty(PCVP)with polymethyl methacrylate bone cement(PMMA)injection in the treatment of osteoporotic vertebral compression fractures(OVCF).Methods:A total of 84 patients with OVCF treated in Beihu Hospital in Xinyu,Jiangxi Province from January 2020 to May 2022 were selected and divided into two groups according to the random number table method.Both groups were treated with PCVP,the calcium phosphate cement(CPC)group was treated with CPC as filler,and the PMMA group was treated with PMMA as filler.The height of the anterior edge of the injured vertebral body,Cobb angle,pain degree,intraoperative fluoroscopy frequency,bone cement perfusion volume and leakage rate were compared between the two groups.Results:The postoperative visual analogue scale(VAS)score in the PMMA group was significantly lower than that in the CPC group(P<0.05);there were no significant differences in the height of the anterior edge of the injured vertebral body,Cobb angle,intraoperative fluoroscopy frequency,bone cement perfusion volume,and bone cement leakage rate between the two groups(P>0.05).Conclusion:Both PMMA and CPC can restore vertebral height and correct kyphosis deformity for OVCF in PCVP,however,PMMA injection has a better short-term pain relief effect and does not increase the incidence of bone cement leakage.
