椎体后凸成形术中骨水泥渗漏的影像学观察.pdfVIP

解与术前相比差异有统计学意义 （P0.05 ），两组患者术后与末次随 访腰背疼痛VA S 评分比较无统计学意义（P0.05 ）。OVBF 组患者中 无骨水泥渗漏与渗漏者相比术后及末次随访时 VAS 评分无显著性差 异 （P0.05 ）；OVCF 组中无骨水泥渗漏与渗漏者相比术后及末次随 访时VAS 评分无显著性差异 （P0.05 ）。OVBF 和OVCF 组中骨水泥 渗漏入椎管的两组患者术后及末次随访 VAS 评分差异无统计学意义 （P0.05 ）。OVBF 和OVCF 组中骨水泥渗漏到椎间隙内的两组患者 术后和末次随访时VAS 评分差异无统计学意义（P0.05 ），腰背痛均 明显缓解。结论：1、骨质疏松性爆裂骨折行经皮椎体后凸成形术椎 管内渗漏率与骨质疏松性压缩骨折相似。骨水泥向椎管内渗漏的主要 途径可能是通过椎基静脉孔或椎基静脉。2 、骨质疏松性爆裂骨折行 经皮椎体后凸成形术椎间隙内渗漏率明显高于骨质疏松性压缩骨折， 可能与椎体骨折时上下终板损伤较重有关。3、经皮椎体后凸成形术 后骨质疏松性爆裂骨折患者椎体高度明显恢复、后凸畸形明显改善， 椎体后壁骨折块无明显移位，椎管狭窄程度无明显增加。4 、经皮椎 体后凸成形术治疗骨质疏松性脊柱骨折腰背部疼痛缓解与骨折类型、 骨水泥是否渗漏及骨水泥渗漏的部位和途径无关。 关键词 经皮椎体后凸成形术 骨质疏松性爆裂骨折 骨质疏松 性压缩骨折 骨水泥渗漏 3 Imaging observation of PMMA in Percutaneous kyphoplasty Abstract [Objective] Osteoporotic vertebral fractures is divided into Osteoporotic vertebral compression fracture(OVCF) and Osteoporotic vertebral burst fracture(OVBF) according to imaging observation.By the retrospective observation of the PMMA site and main way of the two groups of patients in Percutaneous kyphoplasty(PKP),to discuss the feasibility and safety of treatment of kyphoplasty osteoporotic burst frac -ture.[Methods]Four hundred fifty cases of patients with osteoporotic vertebral fractures were treated using PKP in spinal surgery department of the Affiliated Hospital of Luzhou Medical College from October 2005 to May 2012.According to the postoperative complete image datas,the patients were divided into OVBF and OVCF groups.32 OVBF patients with 32 vertebraes who satisfied the inclusion criteria were taken as the study group,and 289 vertebrates of 269 OVCF patients were taken as the control group.The PMMA of the two groups of the patients was divided into:spinal canal,intervertebral disc
