摘要
目的旨在了解健康与髋部骨折老年妇女股骨近端骨密度及其形态上的几何学差异。方法用双能Ｘ线吸收法测量３３例髋部骨折及１０３例健康老年妇女的股骨颈骨密度（ＢＭＤ）和髋轴长度（ＨＡＬ），进行组间比较。结果髋部骨折老年妇女股骨颈ＢＭＤ为０．６０４６±０．１１９０ｇ／ｃｍ２，低于健康老年妇女的０．７２９５±０．１０１７ｇ／ｃｍ２，其ＨＡＬ为１０．６５±０．９８ｃｍ，高于健康老年妇女的１０．２３±０．８４ｃｍ（均为Ｐ＜０．０１）。健康老年妇女ＨＡＬ与股骨颈ＢＭＤ及年龄因素均无相关关系（分别为ｒ＝０．０７和０．１２，Ｐ＞０．０５）。结论髋轴长度是能够独立区分髋部骨折老年妇女与健康人群的测量指标。
Objective To find the differences of bone mineral density (BMD) and geometry of proximal femur between healthy and hip fracture aged women. Methods BMD and hip axis length (HAL) of proximal femur were measured by dual energy Xray absorptiometry (DXA) in 33 aged (>60 years old) hip fracture women and 103 healthy aged women. Results The mean femoral neck BMD value of hip fracture aged women was 06046±01190g/cm2,statistically smaller than 07295±01017g/cm2; and their mean HAL 1065±098cm was longer than 1023±084cm of the healthy control group (P<001,respectively). There was no relationship between HAL and age (r=012) or femoral neck BMD (r=007) in 103 healthy aged women. Conclusions HAL can be taken as an index to distinguish hip fracture from healthy aged women population independent of BMD measurement of proximal femur.
