Abstract：
OBJECTIVE: Balloon kyphoplasty (BKP) is an effective procedure for osteoporotic vertebral compression fractures; however, there is limited data regarding its outcomes in patients aged ≥81 years. This study investigated the treatment outcomes and prognostic factors for BKP in this age group.
METHODS: A retrospective analysis was conducted on 115 patients with osteoporotic vertebral compression fracture undergoing single-level BKP after failed conservative treatment, classified into the <81 years (n=70) and ≥81 years (n=45) groups. Surgical results were evaluated as good outcomes (independent indoors 1 year postoperatively) and poor outcomes, followed by univariate and multivariate analyses to determine prognostic factors correlating with these outcomes.
CONCLUSIONS: The majority of patients (<81 years: 85.7%; ≥81 years: 73.3%) had a good degree of independence at 1 year postoperatively, which was comparable in both groups. Further analysis of patients aged ≥81 years showed that longer duration from onset to surgery, more subsequent vertebral fractures, and lower preoperative body mass index were correlated with poorer outcomes postoperatively, and low body mass index, time from onset to surgery, and female sex were independent risk factors for these outcomes (area under the receiver operating characteristics curve: 0.91).

摘要：
球囊椎体后凸成形术(BKP)是治疗骨质疏松性椎体压缩性骨折(OVCFs)的有效方法;在≥81岁的患者中,关于其结局的数据有限.本研究调查了该年龄组BKP的治疗结果和预后因素。回顾性分析115例保守治疗失败后接受单水平BKP治疗的OVCF患者，分为<81岁(n=70)和≥81岁(n=45)组。手术结果被评估为良好结果（术后1年在室内独立）和不良结果，然后进行单因素和多因素分析,以确定与这些结局相关的预后因素.大多数患者（<81岁：85.7％；≥81岁：73.3％）在术后1年具有良好的独立性，两组具有可比性。对年龄≥81岁的患者的进一步分析显示，从发病到手术的持续时间更长，更多的后续椎骨骨折，较低的术前体重指数（BMI）与术后较差的结局相关，低BMI,从发病到手术的时间，和女性是这些结局的独立危险因素(受试者工作特征曲线下面积:0.91).
