经皮椎体成形术不同骨水泥注入方式在老年腰椎压缩性骨折中的疗效与安全性对比OA

Objective:To compare the efficacy and safety of three bone cement injection methods in percutaneous vertebroplasty(PVP):conventional injection,pressurized injection,and staged injection in elderly lumbar compression fractures.Method:A retrospective selection was made of 90 elderly patients with lumbar compression fractures in Shangrao Municipal Hospital from August 2022 to August 2024.According to the treatment methods,the patients were divided into three groups:conventional injection group(n=30,conventional injection of bone cement),pressurized injection group(n=30,pressurized injection of bone cement),and staged injection group(n=30,staged injection of bone cement).All of them underwent PVP.The vertebral height,pain condition,the distribution,filling rate and injection volume of bone cement,and the safety among the three groups were compared.Result:Compared with the conventional injection group and the staged injection group,the VAS score in the pressurized injection group was lower one week after operation(P<0.05).The comparison of VAS scores of the three groups 1 and 3 months after operation showed no statistically significant differences(P>0.05).One month after operation,the anterior edge and middle heights of the vertebrae in the pressurized injection group were higher than those in the conventional injection group and the staged injection group(P<0.05).There was no significant difference in the posterior edge height of the vertebrae 1 month after operation among the three groups(P>0.05).There was no significant difference in bone cement diffusion classification among the three groups(P>0.05).The bone cement sufficient filling rate in the pressurized injection group was higher than that in the conventional injection group and the staged injection group(P<0.05).The bone cement injection volume in the pressurized injection group was greater than that in the conventional injection group and the staged injection group(P<0.05).The incidence of complications in the staged injection group was lower than that in the conventional injection group(P<0.05).Conclusion:Pressurized injection of bone cement is more effective in recovering the anterior edge and middle heights of the vertebrae and relieving early pain,and staged injection of bone cement is the best in improving safety.
