Study On The Relationship Between The Diffusion Range Of Bone Cement And The Efficacy Of Vertebroplasty

Objactive:The correlation between poor bone cement dispersion during operation and the efficacy of percutaneous vertebroplasty was analyzed to provide theoretical and clinical guidance for PVPS.Method:This study used a retrospective study method.From March 2018 to September 2019,99 inpatients(99 vertebral bodies)who underwent percutaneous coneoplasty at the 6th Affiliated Hospital of New Medical University received single-segment bone surgery Medical records and imaging data of patients with osteoporotic vertebral compression fractures(OVCF).According to the postoperative X-ray orthotopic bone cement dispersion,it was divided into two groups A(over the midline group)and B(not over the midline group),and compared the A and B groups:(1)baseline data comparison(2)Perioperative situation(3)Comparison of efficacy and complications.Result:Postoperative pain was significantly relieved in all patients.Statistical analysis showed that there were no significant differences in postoperative pain relief and nerve damage between the two groups of patients.The incidence of bone cement leakage in group A(over the midline group)was higher than in group B(under the midline group).However,the re-collapse rate of injured vertebrae in group B was higher than that in group A(28.8%VS 7.7%).Conclusion s:This study investigated the effect of poor bone cement dispersion on the efficacy of surgery in PVP.Poor bone cement dispersion within the vertebral body increased the risk of vertebral collapse.The more widely the bone cement is distributed in the vertebra,the higher the risk of leakage.
