Different Morphometric and Densitometric Parameters Predict Cervical and Trochanteric Hip Fracture: The EPIDOS Study

摘要: We used an experimental software measuring the hip axis length (HAL) and bone mineral density (BMD) in specific regions of lower upper part femoral neck on dual-energy X-ray absorptiometry scans. To determine whether these parameters were significant predictors type fracture, we measured 167 healthy women (controls), 24 with trochanteric, 42 cervical fractures within EPIDOS prospective cohort. is a multicenter study risk factors for fracture performed 7575 elderly living at home, aged 75-95 conducted five French centers (Amiens, Lyon, Montpellier, Paris, Toulouse). Measurements data acquired baseline before occurrence fracture. In group, HAL was significantly longer than controls (94.2 vs. 92.3, p = 0.03), associated odds ratio (OR) adjusted age, weight, total BMD (OR 1.64, 95% confidence interval [CI] 1.06-2.55). contrast, not different from trochanteric group. Femoral diameter predictor The group controls, both measurements predicted prediction enhanced by only 2.79 1.97 neck) while controls. Hip distribution between fractures. These results support hypothesis pathophysiological mechanism two types
