股骨上段几何结构在老年妇女髋部骨折发生中的作用

目的探讨股骨上段几何结构与老年女性髋部骨折之间的关系。方法髋部骨折老年妇女43例和无骨折的老年妇女48例，腰椎骨密度检测均提示骨质疏松，拍摄包括股骨上段的X线骨盆平片，分析其Singh指数、股骨头直径(HD)、股骨颈最窄处的宽度(ND)、股骨头中心至股骨轴的距离(NL)、颈干角(NSA)及股骨上段皮质骨厚度。结果骨折组股骨上段皮质骨厚度为（10.9±3.1）mm；对照组为（13.2±2.9）mm，两组之间差异有显著性(P＜0.05)；骨折组的Singh指数Ⅲ度以下占86.05%，对照组为66.67%，两组之间差异有显著性(P＜0.05)；而两组之间HD、ND、NL、NSA差异均无显著性(P＞0.05)。结论股骨上段骨皮质厚度和Singh指数对老年妇女髋部骨折发生有一定的影响。

The role of geometry of upper femur on hip fracture in elderly women

Objective　To investigate the relationship of proximal femur geometry and hip fracture in elderly women. 　Methods　 We compared proximal femur measurements made from the uninvolved hip of 48 plane anteroposterior pelvis radiographs of elderly women without fracture to those of the contralateral hip in a group of 43 cases with hip fracture. Measurements of Singh index, head diameter(HD), neck diameter(ND), femoral neck length(NL), neck shaft angle(NSA) and cortical thinckness of proximal femur were analyzed. 　Results　 The cortical thickness of proximal femur in hip fracture and without hip fracture groups was (10.9±3.1) mm and (13.2±2.9) mm, and the Singh index below Ⅲ° was 86.05% and 66.67%, respectively. No difference in HD,ND,NL and NSA could be demonstrated.　Conclusions　 Singh index and cortical thickness of proximal femur may be used to predict the occurrence of the hip fracture in elderly women.
