Characteristics of bone biochemical indices in predicting secondary osteoporotic fracture after intertrochanteric fracture in elderly women

摘要

Summary Background This study aimed to explore the characteristics of bone biochemical indices, including bone mineral density (BMD), metabolic markers in elderly women with osteoporotic intertrochanteric fracture and their relevance in secondary fracture. Methods The standard for follow-up from 58 elderly women was established to analyse the BMD in the injured hip, healthy hip, and the vertebra at 1 week and 12 months after fracture. The serum levels of total procollagen type N-terminal propeptide (tPINP) and the age-related type I cross linked C-telopeptide (β-CTX) were recorded and compared between those patients with and without secondary fractures within 12 months. Results Twelve months after fracture, the serum levels of tPINP and β-CTX were significantly higher than the baseline values ( p ?
