Preoperative imaging findings to predict good outcome after percutaneous vertebroplasty

目的：为了探讨预防性经皮椎体成形术后继发骨折的危险因素，材料和方法：本研究包括116例接受预防性经皮椎体成形术的椎体压缩性骨折患者。我们分析了以下多个协变量以确定它们是否与复发相关：年龄、性别、类固醇使用和术前未愈合或慢性压缩性骨折的数量。结果：三处或三处以上骨折的患者后续骨折的发生率显著高于一处骨折的患者（p < 0.05）。其他因素无统计学显著差异。

OBJECTIVE: To investigate risk factors for subsequent fractures after prophylactic percutaneous vertebroplasty.MATERIALS AND METHODS: This study included 116 patients with osteoporotic compression fractures who underwent prophylactic percutaneous vertebroplasty. We analyzed the following multiple covariates to determine whether they were associated with recurrence: age, sex, steroid use, and the preoperative number of unhealed or chronic compression fractures.RESULTS: The incidence of subsequent fractures was significantly higher in patient s with three or more fractures than in those with one fracture (p < 0.05). There were no statistically significant differences for the other factors.
