Hip fractures have high morbidity and mortality rate for the people as a complication of osteoporosis and is generally seen in old age. It is known that femoral geometric measurements are important in the assessment of hip fracture risks. This study aimed to examine the association between hip geometry and hip fracture in post-menopausal elderly females. In the present study, 232 hip X-rays were taken from women with no hip fractures (Group 1) and 29 post-menopausal women with hip fractures (Group 2) after a minor trauma. After standard anterior-posterior plain pelvic X-ray radiographs were obtained, various radiographic measurements were performed in all cases, including the hip axis length (HAL), femoral neck axis length (FAL), acetabular width (AW), femoral head width (HW), femoral neck width (FW), femoral shaft width (FSW), intertrochanteric width (TW), lateral and medial cortical thickness of the femoral shaft (LCT, SMCT), femoral neck cortical thickness (NMCT) and femoral neck-shaft angle (Q-angle). In group 1, the mean age, weight and height were 62.5 +/- 7.4 years, 70.8 +/- 12.5 kg, and 157.5 +/- 6.7 cm, respectively. In group 2, these values were 70.17 +/- 6.8 years, 64.7 +/- 11.5 kg, and 158.3 +/- 2.7 cm, respectively. There were no statistically significant differences in the measurements of HAL, FAL, AW and HW between the two groups. In group 2, the mean FW value was significantly higher than in group 1 (p= 0.01). The mean values for FSW, TW, NMCT, SMCT, LCT were statistically lower in group 2 than those in group 1 (p= 0.01, p=0.038, p=0.001, p < 0.001, p < 0.001, respectively). Q-angle was also significantly higher in cases with hip fracture than in cases with no hip fracture (p=0.01). The values of FW, FSW, TW, NMCT, SMCT, LCT and Q-angle seem to be important parameters in the evaluation of hip fracture risks. However, further studies are needed to clarify this conclusion.
