摘　　要：目的：分析不同性别、年龄老年骨质疏松性骨折患者不同部位的骨密度（BMD）及骨折阈值。方法选取2010年10月至2013年10月在延安大学附属医院骨科门诊就诊的180例老年骨质疏松性骨折患者作为研究对象。男90例，其中60～69岁45例、70～79岁45例；女90例，其中60～69岁45例、70～79岁45例。比较不同性别、不同年龄段患者股骨颈、Ward三角、L2～L4及大粗隆等部位的BMD；采用ROC曲线计算不同部位的骨折阈值。结果70～79岁股骨颈、Ward三角、大粗隆部位BMD明显低于60～69岁组（P＜0.05）；老年女性患者股骨颈、Ward三角、L2～L4、大粗隆部位BMD均低于老年男性患者（P＜0.05）。老年男性和女性患者股骨颈、Ward三角、L2～L4、大粗隆等部位骨折阈值分别为0.77、0.68、0.81、0.74 g/cm^3和0.74、0.65、0.78、0.71 g/cm^3。结论不同性别和年龄的老年骨质疏松性骨折患者不同部位BMD及骨折阈值均有所不同，年龄和绝经是影响BMD的重要因素。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/cm^3 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.
