髋部骨密度与髋部骨折风险的相关性分析

The correlation between hip BMD and hip fracture

目的探讨不同年龄,不同性别髋部骨折患者的髋部骨密度值与髋部骨折风险的相关性。方法抽取髋部骨折98例,50岁以上85例,其中男性33例,女性52例,股骨颈骨折占44例,粗隆间骨折41例。按照骨质疏松诊断标准共分为2组:T<-2.0(骨折组),T>-2.0(骨折组),按性别、年龄、身高、体重与骨折组按1∶1配对,以T<-2.0(非骨折组),T>-2.0(非骨折组)分别作为对照组。结果年龄50岁以上非暴力髋部骨折患者,T<-2.0(骨折组)和T<-2.0(非骨折组)做对照研究,骨折组的骨密度值要低于非骨折组,对骨折风险预测有显著性差异。男性和女性之间做对照研究,有明显的统计学意义。年龄50岁以上非暴力髋部骨折患者,T>-2.0(骨折组)和T>-2.0(非骨折组)做对照研究,骨折组的骨密度值要低于非骨折组,对骨折风险预测有显著性差异。男性和女性之间做对照研究,有明显的统计学意义。年龄50岁以下的患者为13例,其中男性11例,女性2例,均为年轻的受暴力致伤的患者,骨密度值检测对骨折风险评估没有显著性差异。结论(1)对于非暴力髋部骨折,低BMD与髋部骨折有明显的相关性,且呈指数级相关。(2)骨折危险性的评估没有明确的BMD阈值。(3)骨折患者与非骨折患者BMD有相互重叠。(4)女性自50岁左右髋部骨折的发生率要高于男性。(5)小于50岁的较年轻患者BMD和骨折危险性的相关性不明确。

Objective To evaluate the correlation between hip fracture and BMD in eldedy patients, and identify the fracture risk facotrs for the prevention of fracture. Methods 98 patients of hip fracture, 85 patients over 50 years old, 33 males,52 females, 44 cases of femorl neck fracture and 41 cases of introchantic fracture. Divided into 2 groups according to criterion of osteoprosis diagnosis. T 〈 - 2.0 and T 〉 - 2.0, as a control with T 〈 - 2.0 （no fracture）and T 〉 - 2.0 （ no fracture）, to study the correlation between BMD and fracture. Results The patients aged more than 50 years old,BMD in fracture and non-fracture,according to SAS test, P 〈 0.01, but there is no accurate BMD accordingly. The patients aged less than 50 years old, there is no correlation between BMD and fracture between fracture and non-fracture, there is BMD overlapping. Conclusion To non-violent patients, there is significant correlation between BMD and fracture, but with accurate BMD accordingly. The patient with fracture and non-fracture,there is BMD overlaping. For patients over 50 years old, the fracture incidence in female is higher than in male. For patients under 50 years old, there is no definite correlation.
