摘要:

 目的 分析骨水泥/椎体体积比与经皮椎体成形术(PVP)后邻近椎体压缩骨折(AVCF)的相关性。方法 回顾性分析陕西省康复医院脊柱外科2018年6月至2022年6月收治的202例行PVP治疗的骨质疏松性椎体压缩骨折患者的临床资料,其中男89例、女113例,年龄56~78(67.98±6.93)岁,术后随访6~12(8.32±2.31)个月。根据术后是否发生AVCF将其分为AVCF组(31例)和无AVCF组(171例)。对两组患者人口特征资料、体重指数、骨密度、骨水泥渗漏、骨水泥体积(BCV)、较大侧骨椎体体积(LSBCV)、椎体体积(VBV)、BCV/VBV、LSBCV/VBV等指标进行单因素和多因素logistic回归分析。绘制受试者操作特征曲线(ROC)分析各影响因素预测PVP术后AVCF的效能。采用独立样本t检验、χ2检验进行统计学分析。结果 术前骨密度T值、LSBCV、LSBCV/VBV、骨水泥渗漏情况对PVP术后AVCF有显著影响(均P<0.05)。多因素logistic回归分析显示,低术前骨密度T值(OR=0.377)、高LSBCV/VBV(OR=2.123)是PVP术后发生AVCF的独立危险因素(均P<0.05)。术前骨密度T值预测PVP术后发生AVCF的曲线下面积(AUC)为0.638(0.559~0.746);LSBCV/VBV的AUC为0.800(0.723~0.877),最佳诊断阈值为13.859%,此时LSBCV/VBV预测PVP术后发生AVCF的灵敏度、特异度、约登指数、阳性预测值、阴性预测值分别为83.87%、66.67%、0.505、31.33%、95.80%。结论 低术前骨密度T值、高LSBCV/VBV是PVP术后发生AVCF的独立危险因素,LSBCV/VBV对PVP术后AVCF有一定预测价值。

Abstract:

Objective To analyze the correlation between bone cement/vertebral body volume ratio and adjacent vertebral compression fractures (AVCF) after percutaneous vertebroplasty (PVP). Methods The clinical data of 202 patients with osteoporotic vertebral compression fracture treated by PVP from June 2018 to June 2022 in the Department of Spinal Surgery of Shaanxi Provincial Rehabilitation Hospital were retrospectively analyzed, including 89 males and 113 females, with an age of 56-78 (67.98±6.93) years old, followed up for 6-12 (8.32±2.31) months. According to whether AVCF occurred after operation, the patients were divided into an AVCF group (31 cases) and a non-AVCF group (171 cases). Univariate and multivariate logistic regression analysis were used to analyze on demographic data, body mass index, bone density, bone cement leakage, bone cement volume (BCV), larger vertebral body volume (LSBCV), vertebral body volume (VBV), BCV/VBV, LSBCV/VBV, and other indicators for two groups. The receiver operator characteristic curve (ROC) was used to analyze the efficacies of influencing factors in predicting AVCF after PVP. Independent sample t test and χ2 test were used for statistical analysis. Results Preoperative bone mineral density T value, LSBCV, LSBCV/VBV, and bone cement leakage had significant effects on AVCF after PVP (all P<0.05). Multivariate logistic regression analysis showed that low preoperative bone mineral density (OR=0.377) and high LSBCV/VBV (OR=2.123) were independent risk factors for AVCF after PVP (both P<0.05). The area under the curve (AUC) of preoperative bone mineral density in predicting the occurrence of AVCF after PVP was 0.638 (0.559-0.746). The AUC of LSBCV/VBV was 0.800 (0.723-0.877), and the optimal diagnostic threshold was 13.859%; the sensitivity, specificity, Youden index, positive predictive value, and negative predictive value of LSBCV/VBV in predicting the occurrence of AVCF after PVP were 83.87%, 66.67%, 0.505, 31.33%, and 95.80%, respectively. Conclusion Low preoperative bone mineral density T value and high LSBCV/VBV are independent risk factors for AVCF after PVP, and LSBCV/VBV has certain predictive value for AVCF after PVP.
