When BMD was reduced by 24% over or laminated cortex index of ulna and radius was less than third degree in females, fracture might happen. 女性骨矿量下降24%以上或尺、桡骨骨皮质分层指数为Ⅲ°以下时,预示可能会发生骨折。
Conclusions SPA is more sensitive than laminated cortex index of radius and ulna, but it is not specific. Therefore, it is more suitable for dynamic monitoring of BMD. 结论SPA较桡尺骨皮质分层指数敏感,但缺乏特异性,更适用于动态监测骨矿含量变化情况。
