Abstract Summary Beta values of the intertrochanteric fracture group were about twice as high as those of the femoral neck fracture group. These results can be used to increase the awareness of proximal hip fracture among physicians and improve treatments and outcomes. Purpose To compare the BMD of the femoral neck region and the intertrochanteric region between the femoral neck fracture group and the intertrochanteric fracture group. Methods We did a retrospective review of radiographs of the proximal femoral fractures in patients registered from 2010 to 2017. A total of 329 patients were classified into the femoral neck fracture group (group A, n = 162) and the femur intertrochanteric fracture group (group B, n = 167). We did intergroup comparisons of age, sex, BMI (body mass index), and bone mineral density (BMD) of the neck and intertrochanteric region, adjusting for age. We did multiple logistic regression analysis among these parameters. Results The BMD of the femoral neck and intertrochanteric was statistically significantly different between the two groups (p < 0.001), and the BMD of the femur intertrochanteric was also significantly different between the two groups (p < 0.001). BMD of both regions in the intertrochanteric fracture group was lower than that of the femoral neck fracture group. In linear regression analysis, the beta values of the intertrochanteric fracture group were about twice as high as those of the femoral neck fracture group. Conclusion In linear regression analysis, the beta values of the intertrochanteric fracture group were about twice as high as those of the femoral neck fracture group.

Introduction Proximal femur fracture is a worldwide problem related to the aging of the population [1–5]. The incidence of proximal femur fractures is increasing each year because of the increase in the number of the elderly [6]. Furthermore, Melton et al. expected that 63 million hip fractures will occur globally in 2050 [3, 4]. Because proximal femur fracture is a leading cause of morbidity

and mortality in the elderly [7–9], it is the most serious complication of osteoporosis and the most disabling type of fracture in the elderly population [7, 10]. The 1-year mortality in elderly patients ranges from 14 to 36% [6]. One-year mortality in patients who
