Abstract:

Objective　To analyze the influencing factors of recurrent fracture after percutaneous vertebroplasty (PVP) in elderly patients with osteoporotic thoracolumbar compression fracture (OVCF). Methods　Sixty-nine patients with OVCF who were treated in Hanzhong Hospital of Traditional Chinese Medicine from January 1, 2020 to December 31, 2023 were retrospectively analyzed, and were divided into two groups according to whether or not they had a recurrent fracture after PVP. General data such as age, gender, and body mass index were collected and analyzed in the two groups. The influencing factors of recurrent fractures after PVP were analyzed by multivariate logistic regression analysis. Independent sample t test and χ² test were used for statistical analysis. Results　At 6 months of follow-up, 14 of 69 patients with OVCF had recurrent fractures after PVP, with an incidence of 20.29%. Univariate and multivariate analysis showed that age, bone mineral density, and bone cement leakage were the influencing factors for recurrent fractures after PVP in elderly OVCF patients (all P<0.05). Conclusion　Age, bone mineral density lower than normal, and bone cement leakage are risk factors for recurrent fracture after PVP in elderly OVCF patients.

摘要：

目的　分析老年骨质疏松性胸腰椎压缩骨折（OVCF）患者经皮椎体成形术（PVP）后再发骨折的影响因素。方法　回顾性分析2020年1月1日至2023年12月31日于汉中市中医医院就诊的69例OVCF患者，根据PVP术后是否再发骨折分为发生组与未发生组。收集并分析两组患者的年龄、性别、体重指数等一般资料，通过多因素logistic回归分析PVP术后再发骨折的影响因素。采用独立样本t检验、χ²检验进行统计学分析。结果　术后6个月随访时发现，69例OVCF患者PVP术后有14例再发骨折，发生率为20.29%。经单因素及多因素分析发现，年龄、骨密度、骨水泥渗漏是老年OVCF患者PVP术后再发骨折的影响因素（均P<0.05）。结论　高龄、骨密度水平低于正常值、骨水泥渗漏是老年OVCF患者PVP术后再发骨折的危险因素。
