A retrospective study of the data on 27,370 hospital discharges of patients who had been admitted to non-federal Maryland hospitals from 1979 through 1988 for a fracture of the proximal part of the femur and who had been at least sixty-five years old at the time of the fracture showed that the ratio of trochanteric fractures to fractures of the femoral neck increased linearly with age in white and black women. For men, this ratio was stable across age-intervals, being slightly more than one in white men and less than one in black men. Black patients who had a fracture of the hip were more likely than white patients to have a subtrochanteric, open, or femoral neck fracture. The rate of occurrence of fractures of the hip was highest in white women; the rate decreased successively in white men, black women, and black men. The higher over-all rate of fractures of the hip in white patients was disproportionately influenced by the much higher rate of trochanteric fractures in these patients.
一项回顾性研究分析了1979年至1988年间因股骨近端骨折入住马里兰州非联邦医院、骨折时年龄至少为65岁的27370名患者的出院数据。结果显示，在白人女性和黑人女性中，转子间骨折与股骨颈骨折的比例随年龄呈线性增加。对于男性，该比例在各年龄组中保持稳定，白人男性略高于1，黑人男性低于1。髋部骨折的黑人患者比白人患者更有可能发生转子下、开放性或股骨颈骨折。髋部骨折的发生率在白人女性中最高；在白人男性、黑人女性和黑人男性中依次降低。白人患者总体较高的髋部骨折发生率在很大程度上受到这些患者较高的转子间骨折发生率的影响。
