为了探讨两种主要髋部骨折类型的潜在病因差异，作者计算了股骨颈和股骨近端粗隆区骨折的发生率，使用了5%的美国65-99岁医疗保险人群的样本。在1986年7月1日至1990年6月30日的研究期间，两种髋部骨折类型的发生率随年龄增长而增加。发生在股骨粗隆区的髋部骨折的比例在白人女性中随着年龄的增长而急剧上升，但在黑人女性、白人男性和黑人男性中则没有。在美国，两种骨折类型的发生率在女性中呈南北梯度，而在男性中没有发现明确的模式。这些发现提出了两种骨折类型存在病因差异的可能性，并为骨质疏松性骨折风险的性别和种族差异提供了进一步的证据。
To explore potential etiologic differences in the two major types of hip fracture, the authors computed the incidence rates of fractures of the femoral neck and trochanteric region of the proximal femur using a 5% sample of the US Medicare population aged 65–99 years. For the period they examined, July 1, 1986, through June 30, 1990, the rates of both hip fracture types increased with age in all race and sex categories. The proportion of hip fractures that occurred in the trochanteric region rose steeply with age among white women, but not among black women, white men, or black men. Within the United States, a north-to-south gradient in rates of both fracture types was observed among women, while no clear pattern was found for men. These findings raise the possibility of etiologic differences in the two fracture types, and the results provide further evidence of sex and racial differences in the risk of osteoporotic fractures.
