目的:分析骨质疏松性髋部骨折和股骨颈抗压强度指数(CSI)的关系,为评估老年人骨质疏松性髋部骨折的危险性提供参考依据。方法:选择骨质疏松性髋部骨折老年病人30例(病例组)和其他非骨折老年病人42例(对照组),测定股骨颈骨密度(BMD)、股骨颈宽度(FNW)和体重,计算出股骨颈CSI;用Logistic回归方法分析股骨颈CSI与髋部骨折危险性的关系。结果:股骨颈CSI值越低,髋部骨折危险性越大;髋部骨折危险性大于10%时,男性髋部骨折股骨颈CSI闽值为0.035;危险性大于20%时,女性髋部骨折股骨颈CSI闽值为0.032。结论:老年人股骨颈CSI与骨质疏松性髋部骨折危险性有关,可以作为预测髋部骨折发生的指标之一。
Objective: To analyze the relationship between osteoporotic hip fracture and femoral neck compressive strength index (CSI), and to provide a reference for evaluating the risk of osteoporosis hip fracture in the elderly. Methods: 30 elderly patients with osteoporotic hip fracture (case group) and 42 non-fractured elderly patients (control group) were enrolled in the study. BMD, FNW and body weight of femoral neck were measured. The femoral neck CSI was obtained. Logistic regression was used to analyze the relationship between femoral neck CSI and hip fracture risk. Results: The lower the femoral neck CSI, the greater the risk of hip fracture. When the risk of hip fracture was more than 10%, the femoral neck CSI of male hip fracture was 0.035 and the risk of hip fracture was more than 20% Femoral neck CSI threshold 0.032. Conclusion: CSI of the femoral neck is related to the risk of osteoporosis hip fracture, which may be used as an index to predict the occurrence of hip fracture.
