Abstract:
Objective:To explore the value of material separation technique based on energy spectrum CT in predicting the recurrence of osteoporotic vertebral fractures after operation, in order to provide reference for the evaluation of postoperative recurrence of fractures.Methods:A total of 80 cases with percutaneous vertebroplasty (PVP) treated in the First People’s Hospital of Shangqiu, Henan Province from Jan. 2020 to Dec. 2021 were selected for pre-operative CT material separation examination and postoperative follow-up for at least 2 years. The patients were divided into recurrence group and no recurrence group according to the recurrence of fracture. The clinical data and the results of material separation technique by energy spectrum CT were compared. The relevant factors for fracture recurrence was assessed by Logistic regression analysis, and ROC curve was used to evaluate the predictive value of material separation technique based on energy spectrum CT in the recurrence of fracture.Results:After a follow-up of at least 2 years, 26 of the 80 patients had a recurrence of the fracture. The age, calcium water and hydroxyapatite (HAP) -water values in recurrent group were higher than those in no recurrent group, and the proportion of bone cement leakage was higher ( t/ Fisher=2.57, 5.40, 3.96, - P = 0.012 < 0.001, < 0.001, 0.033) . Logistic regression analysis showed that calcium-water ( OR=2.321, 95%CI: 1.464-3.679) and HAP-water ( OR=1.784, 95%CI: 1.246-2.554) values were the factors for postoperative fracture recurrence in osteoporotic fractures ( P<0.001) . ROC curve showed that AUC, sensitivity and specificity of combined calcium-water and HAP-water values in predicting postoperative fracture recurrence were 0.868, 88.46% and 79.63%, respectively ( P<0.001) . Conclusions:The material separation technique based on energy spectrum CT in predicting the recurrence of osteoporotic vertebral fractures after operation has high clinical application value, and provides a new idea for the clinical evaluation of postoperative recurrence of fractures.
