椎体松质骨CT值联合骨密度值比率对新鲜与陈旧骨质疏松性椎体压缩骨折的鉴别诊断价值

Differential Diagnostic Value of the Ratio of Vertebral Cancellous Bone CT Value Combined with Bone Density Value in Fresh and Old Osteoporotic Vertebral Compression Fractures

【目的】探讨椎体松质骨CT值联合骨密度值比率对新鲜与陈旧骨质疏松性椎体压缩骨折的鉴别诊断价值。【方法】取2019年1月至2022年1月在榆林市中医医院就诊的82例(共82处椎体)骨质疏松性椎体压缩骨折患者,根据磁共振成像(MRI)检查结果分为新鲜骨折(观察组,n=50)和陈旧性骨折(对照组,n=32),比较两组椎体松质骨CT值、骨密度值比率;采用Logistic多因素分析新鲜骨质疏松性椎体压缩骨折的影响因素;采用受试者工作特征(ROC)曲线分析椎体松质骨CT值及骨密度值比率对新鲜骨折椎体、陈旧骨折椎体的诊断效能。【结果】观察组椎体松质骨CT值高于对照组(P<0.05),骨密度值比率低于对照组(P<0.05)。Logistic多因素分析结果显示:椎体松质骨CT值、骨密度值比率均是新鲜骨质疏松性椎体压缩骨折的影响因素(P<0.05)。椎体松质骨CT值及骨密度值比率鉴别诊断新鲜骨折椎体、陈旧骨折椎体的AUC分别为0.654、0.703,联合鉴别诊断新鲜骨折椎体、陈旧骨折椎体的AUC为0.856。【结论】椎体松质骨CT值、骨密度值比率对新鲜骨折椎体及陈旧骨折椎体均有一定的鉴别价值,其联合鉴别诊断新鲜骨折椎体、陈旧骨折椎体的价值更高。

【Objective】To explore the differential diagnostic value of the ratio of vertebral cancellous bone CT value combined with bone density of in fresh and old osteoporotic vertebral compression fractures.【Methods】A total of 82 patients with osteoporotic vertebral compression fractures(82 vertebrae in total)who were treated at Yulin Hospital of Traditional Chinese Medicine from January 2019 to January 2022 were divided into fresh fractures(observation group)based on the results of magnetic resonance imaging(MRI)examination,n=50 and old fractures(control group,n=32),The CT values and bone density ratio of two groups of vertebral cancellous bone were compared;Logistic multiple factor analysis was used to investigate the influencing factors of fresh osteoporotic vertebral compression fractures;The diagnostic efficacy of CT values and bone density ratio of vertebral cancellous bone for fresh and old fractured vertebrae was analyzed using receiver operating characteristic(ROC)curves.【Results】The CT value of vertebral cancellous bone in the observation group was higher than that in the control group(P<0.05),and the bone density ratio was lower than that in the control group(P<0.05).The results of logistic multivariate analysis showed that CT values and bone density ratio of vertebral cancellous bone were both influencing factors for fresh osteoporotic vertebral compression fractures(P<0.05).The AUC of fresh and old fractured vertebrae was 0.654 and 0.703,respectively,in the differential diagnosis of vertebral cancellous bone CT value and bone density ratio.The AUC of combined differential diagnosis of fresh and old fractured vertebrae was 0.856.【Conclusion】The CT value and bone density ratio of vertebral cancellous bone have certain differential value for fresh and old fractured vertebrae,and their combined differential diagnosis has higher value for fresh and old fractured vertebrae.
