摘要
目的探讨经皮球囊椎体后凸成形术(PKP)骨水泥形态分布对于治疗效果的影响。方法自2007年1月～2010年8月对56例(67椎)脊柱骨质疏松性压缩骨折(OVCF)进行PKP手术,依据骨水泥形态,将其划分为点式支撑组、平面支撑组和立体支撑组,比较术前、术后7 d、12个月VAS评分,术后12个月椎体高度丢失率,以及邻近节段术前及术后12个月椎体骨密度变化。结果术后12个月,3组间VAS比较有显著差异(P=0.003),LSD检验,A组与B组、C组比较比较有显著差异(P=0.003,P=0.002)。术后12个月3组的椎体高度比较有显著差异(P=0.013),LSD检验,A组与B组、C组比较有统计学差异(P=0.001,P=0.001)。术后12个月邻近椎体平均骨密度t值变化,3组间比较有统计学差异(P=0.021),LSD检验,A组与B组、C组比较有统计学差异(P=0.171,P=0.023),B组与C组比较P=0.031。结论 PKP手术的骨水泥形态对于治疗结果有影响,平面支撑骨水泥形态具有较好的应力分配特性。
Objective To analyze the clinical effect of different cement shape after percutaneous kyphoplasty. Methods From January 2007 to August 2010, 56 patients with 67 vertebral body underwent PKP. Depending on the morphology of the cement, the vertebral bodies were divided into three groups. Group A was point supporting type （15 bodies）, group B was flat supporting type（25 bodies）, group C was three dimentional supporting type （27 bodies）. The SPSS 11.5 was used to analyze the differences between three groups in improvement of VAS, the height loss of verebral bodies and bone mineral density change of adjacent vertebral body. Results There were no difference between three groups in VAS at 3rd day and 7th day, But, group B had better VAS at 12th month after operation. Group A had several height loss compared to group C and group B at 12th month after operation. Conclusion Flat supporting cement type has less influence on the BMD of the adjacent vertebral bodies. At the same time, fiat supporting type of cement has better clinical effect in body height loss and VAS.
