摘　　要：目的 探讨单、双侧注入骨水泥及注入骨水泥前灌洗椎体对椎体后凸成形术（KP）、椎体成形术（VP）术后最大垂直载荷的影响.方法 将48个标本分为6组.A、B、E、F组分别行单侧KP、VP手术;C、D组分别行双侧KP、VP手术;E、F组在注入骨水泥前,用生理盐水灌洗椎体.记录术前及术后椎体的最大垂直载荷并进行比较.结果 KP及VP术后椎体的最大垂直载荷差异无统计学意义（A组与B组：t’=0.746,P＞0.05;C组与D组：t’=0.312,P＞0.05;E组与F组：t’=0.830,P＞0.05）;单侧和双侧注入骨水泥后椎体的最大垂直载荷差异无统计学意义（A组与C组：t’=0.374,P ＞0.05;B组与D组：t’=0.529;P＞0.05）;进行生理盐水灌洗对术后椎体最大垂直载荷无明显影响（A组与E组：t’=0.821,P＞0.05;B组与F组：t’=0.449,P＞0.05）.结论 单、双侧注入骨水泥以及注入骨水泥前生理盐水灌洗椎体对术后椎体最大垂直载荷无明显影响,但注入骨水泥前灌洗椎体可增强术后椎体最大垂直载荷.Objective To study if the maximum vertical load was difference when bone cement were inpulsed by unilateral vertebral pedicle and bilateral vertebral pedicle or normal saline on vertebroplasty and kyphoplasty.Methods Select six embalmed vertebral specimens （T8-L5）,free into 48 individual vertebrae were made into compression fracture model.All the specimens were divided into six groups.Group A and B applied unilateral KP and VP respectively,group C and D applied bilateral KP and VP respectively,Group E and F applied unilateral KP and VP with normal saline lavage vertebral body before the injection of bone cement.postoperative loading vertical again,measured the maximum vertical load,recorded the results,using SPSS statistical software for approximate t-test to compare the results.Results There is no significant difference between the maximum vertical loads after VP group and KP group （group A and group B：t＇ =0.746,P＞0.05; group C and group D：t＇ =0.312,P＞0.05; group E and group F：t＇ =0.830,P ＞ 0.05）.There is no significant difference between the maximum vertical loads of unipedicular group and bipedicular group （group A and group C：t＇ =0.374,P ＞ 0.05 ; group B and group D group：t＇ =0.529 ; P ＞ 0.05）.Whether using saline water irrigation or not,postoperative vertebral maximum vertical loads have no significant statistical difference （group A and group E：t＇ =0.821,P ＞0.05 ; group B and group F：t＇ =0.449,P ＞ 0.05）.Conclusion Unilateral or bilateral injection of bone cement did not effect on the maximum vertical load,but the maximum vertical load was increasing after lavaging the specimens.
