骨质疏松症所致的骨折中,以股骨颈骨折影响最大,严重者可因骨折的并发症而导致死亡。对性别、年龄和测量部位的骨量峰值及其骨量下降速度和程度的分析,均有助于骨折危险因素的评估。无论是单独测量腰椎还是股骨颈的骨密度值,都可预测脊椎和股骨颈骨折发生的危险性,但在预测股骨颈骨折危险性方面,股骨颈骨密度测量的敏感性优于腰椎骨密度测量的敏感性;而在预测脊椎骨折危险性方面,股骨颈 Osteoporosis caused by fractures, the femoral neck fracture in the most serious cases of complications due to fracture may lead to death. An analysis of the magnitude and magnitude of bone mass loss at the sex, age, and site of measurement contributes to the assessment of fracture risk factors. Whether measuring the BMD of lumbar spine or femoral neck independently can predict the risk of vertebral and femoral neck fractures, but the femoral neck BMD is superior to lumbar BMD in predicting the risk of femoral neck fracture Sensitivity; while in predicting the risk of vertebral fracture, the femoral neck
