OBJECTIVE: This study’s aim was to investigate the expression changes of total type I procollagen amino-terminal peptide (t-PINP) and type I collagen C-terminal peptide (β-CTX) in serum after vertebral osteoporotic fracture surgery and the clinical value of predicting the risk of refracture.
PATIENTS AND METHODS: The clinical data of 100 patients with vertebral osteoporotic fractures treated in our hospital from January 2019 to January 2020 were retrospectively analyzed, and the patients were divided into the control group (patients without re-fracture, n = 68) and the observation group (patients with re-fracture, n = 32) according to whether they had re-fracture at 2-year follow-up. The risk factors of postoperative re-fracture were analyzed using Multivariate logistic regression analysis. The serum contents of t-PINP, β-CTX, osteocalcin (BGP), and calcium (Ca) were measured. Bone mineral density (BMD) was measured by bone densitometer. The correlation between the t-PINP/β-CTX ratio and the bone ｍmbedbolic index was analyzed by Pearson correlation. The area under the curve (AUC), sensitivity, and specificity of t-PINP/β-CTX in predicting the risk of re-fracture were determined by the receiver operating characteristic (ROC) curve.
