摘　　要：目的 探讨防腐标本椎体成形术与椎体后凸成形术骨水泥渗漏率的差异、渗漏的类型及其原因.方法 选用40个防腐标本椎体,将其制备成压缩骨折模型.其中20个防腐标本椎体行椎体成形术（A组）,另外20个椎体行椎体后凸成形术（B组）.对椎体骨水泥的渗漏及分布进行测定、记录,并对数据行统计学分析.通过CT对骨水泥的渗漏及分布进行评估.结果 A组8个椎体（40％）、B组3个椎体（15％）出现骨水泥渗漏;采用χ^2检验对椎体渗漏率进行比较,差异无统计学意义（P＞0.05）,但提示椎体后凸成形术术后骨水泥渗漏率更低.结论 防腐标本椎体后凸成形术比椎体成形术渗漏率更低,安全性更高,但应在术中严密监测球囊撑开的压力及注入骨水泥的分布.此外,应用高黏度骨水泥能更有效的减少骨水泥渗漏.Objective To test the differences of cement leakage rate,the distribution and reasons of leakage between vertebroplasty and kyphoplasty technique on vertebral body specimens.Methods Forty vertebral body specimens were made into compression fracture model for further test：20 of them were treated with vertebroplasty （group A）,and the rest 20 specimens were proceeded to kyphoplasty procedure （group B）.After surgical treatment,cement leakage and the distribution of cement were identified with reference of CT scan and recorded.Statistical softwares were employed to analyze the data,and differences was regarded as statistically significant when P 〈 0.05.Results Eight cases （40%） of cement leakage were observed in 20 specimens of group A and 3 cases （15%） in group B respectively.χ^2 test was used for the comparison of leakage rate,and it was found there was no statistically significant difference （P 〉0.05）.But it could show a trend：the rate of leakage after kyphoplasty was lower.Conclusion Using a kyphoplasty technique can gain lower leakage rate and higher safety than vertebroplasty.Special attentions should be paid to the pressure of balloon and the distribution of bone cement during surgical procedure.The application of high viscosity bone cement can prevent the leakage of cement effectively.
