Abstract Objective To investigate the value of CT value compression ratio (CTCR) in the diagnosis of disc injury in thoracolumbar osteoporotic compression fractures. Methods A total of 91 patients with thoracolumbar compression fractures from January 2018 to January 2020 were analyzed retrospectively.The diagnostic accuracy of CTCR and loss of vertebral body height(LOVBH) in disc injury was analyzed.The correlation of other CT signs and disc injury were also analyzed. Results The CTCR of the disc injured group was significantly higher(P＜0.001) than that of the disc intact group，but the LOVBH between the two groups showed no significant difference (P＝0.085).In other CT signs，only VBT showed significant difference(P＝0.043) between the two groups.Logistic regression showed that CTCR (OR：4.686，95% CI：1.810~12.133，P＝0.001) was related to disc injury.ROC curve showed that the area under curve (AUC) of CTCR in diagnosing disc injury was 0.750 (P＜0.001)，and the cut-off value was 1.775 (sensitivity：67.4%，specificity：77.8%).Conclusion In the patients with thoracolumbar osteoporotic compression fractures，it is more reliable to use the injured vertebra CTCR to diagnose the disc injury.In view of the universality of CT examination in clinical application，the injured vertebra CTCR can provide the clinicians with the information of disc injury more conveniently.
