Abstract：Objective To determine bone mineral density (BMD) at different regions, and to analyze the threshold of fracture for elderly patients suffered from osteoporostic fractures. Methods From October 2010 to October 2013, 108 elderly patients with osteoporostic fractures from outpatient clinic in the affiliated Hospital of Yan'an University were collected and divided into two gender groups, 90 male and 90 female, in which 45 of them were 60-69 years old and 45 of them were 70-79 years old. BMD at femoral neck, Ward's triangle, L2-L4 and great trochanter were determined and compared respectively among groups with different ages and different gender, threshold value of fracture in different regions was calculated by ROC curve. Results Compared with 60-69 year-old group, BMD at femoral neck, ward's triangle and great trochanter were lower in 70-79 year-old group (P <0.05); For female patients, BMD at the above 4 regions were lower than male patients (P <0.05). The threshold value of fracture at femoral neck, Ward's triangle, L2-L4 and great trochanter in male and female patients was 0.77, 0.68, 0.81, 0.74 g/cm3 and 0.74、0.65、0.78、0.71 g/cm3 respectively. Conclusion Among different gender and different age groups, BMD and threshold value of fracture at different regions were also different for aged patients with osteoporostic fractures, age and menopause are the important factors which can influence BMD.
