Our goal was to provide evidence and guidance for selection and manufacture of clinical prostheses, as well as providing evidence for the accurate reconstruction of proximal femurs in Chinese hip fracture patients.įrom January 2017 to December 2017, 198 patients (44 males and 154 females, mean age ± standard deviation : 77 ± 7 years) with hip fractures were studied. Our study analyzed the geometric parameters of the hip in 198 patients with hip fractures compared to different types of hip fractures. Many other studies have focused on the morphology of hips in Caucasians, but corresponding studies in Asian populations are limited, particularly data on proximal femoral geometric parameters in Han Chinese. Current prosthesis selection in Chinese clinical practice is based on the results of foreign studies, such as the Nobel index of femoral medullary morphology. Some clinical studies have found that results of European and American studies are not entirely applicable to Asian or Chinese people, showing differences in shape, size, and geometry in the proximal femur between racial groups. Therefore, it is of great significance to study the geometric parameters of the hips of elderly patients with hip fractures. A growing number of studies have confirmed that hip bone density and geometry structure are two important determinants of proximal femoral bone strength. This results in a decrease in proximal femur strength and the increased occurrence of hip fractures despite low-energy injuries, such as lateral falls. The increase in the incidence of hip fractures in the elderly is due to decreased bone mass and bone quality. Hip fractures are related to high mortality, long-term disability, and reduced quality of life, and thus, they are the most serious complication of osteoporosis, imposing a heavy burden on the individual, family, society, and health-care system of China. Hip fractures account for 7% of all adult whole-body fractures and 24% in geriatric populations. Hip fractures in the elderly are commonly referred to as femoral neck fractures and intertrochanteric fractures occurring in the elderly, aged 65 years and over. The incidence of hip fractures in the elderly is increasing year by year.
