【摘要】目的:探讨骨质疏松性椎体骨折影像类型与椎体成形术疗效的关系。方法:采用椎体成形术治疗骨质疏松性胸腰椎骨折348例。术前全部进行伤椎影像学检查(包括X光片、MRI及CT)，按椎体骨折影像学形态改变将骨折病例分为5种类型(Ⅰ型：无变形型32例；Ⅱ型：单纯压缩型75例；Ⅲ型：伴非后缘崩裂型139例；Ⅳ型：伴后缘崩裂形65例；Ⅴ型 伴椎管轻度占位型37例)。将五种型椎体骨折病例椎体成形术疗效进行比较分析。结果 随访6个月～12个月， 5种类型中术后疗效以Ⅰ型疗效最佳，完全缓解(CR)率100%。Ⅱ型CR率94.67%，Ⅲ型CR率88.49%，Ⅳ型CR率86.15%，Ⅴ型CR率86.49%。疗效对比结果：除Ⅱ型与Ⅰ型之间对比结果差异无显著性外，其他类型与Ⅰ型对比结果差异均有显著性。骨水泥椎体外渗漏病例数除Ⅱ型与Ⅰ型之间对比结果差异无显著性外，其他类型与Ⅰ型对比结果差异均有显著性。结论:胸腰椎骨折影像诊断类型与椎体成形术疗效、风险直接相关，有重要临床意义。

【Abstract】Objective To explore relation between Image type for osteoporotic vertebral body fractures and curative effects of Percutaneous Verebroplasty (PVP).Methods348 patients with osteoporotic vertebral body fractures in thoracicor lumbar vertebral were treated by PVP. Before the operation, According to their shapes on Image, vertebral fracture were divide into 5 types. model Ⅰ, no shape change type 32 cases; Model Ⅱ, simple compressed type 75 cases; model Ⅲ, crack not at back fringe type 139 cases; model Ⅳ, crack at back fringe type 65 cases,; model Ⅴ, osseous debris intrude canalis vertebralis type 37 cases. Comparison curative effects and cement leak rate between model Ⅰwith other one model. ResultsFollow-up 6 ～12 months, find to that modelⅠcurative effect was best. 32 cases the symptoms complete remission (CR) at all, the CR rate was 100%. Model Ⅱ 75 cases , the CR rate was 94.67%. model Ⅲ 139 cases,the CR rate was 88.49%. model Ⅳ 65 cases, the CR rate was 86.14%. model Ⅴ 37 ases, the CR rate was 86.49%. Curative effect contrast results：except ModelⅠcontrast ModelⅡthe difference was not visible, mode l contrast other model the difference were visible. Cement leak out vertebral body contrast results ：except ModelⅠcontrast ModelⅡthe difference was not visible, mode l contrast other model the difference were visible.Conclusions Image types for vertebral body fractures with curative effect and risks of PVP there are direct relation, there are important significance at clinic ......
