骨质疏松生物力学病因的临床诊断

Diagnosis of Biomechanical Causes of Osteoporosis

本文阐述了细胞生长 与其所受应力的关系论述了骨应力对骨生长的影响,并定量描述了骨髓丢失、生长和破坏的生物力学机制。骨应力的大小直接决定骨代谢的方向,其主要来源不是体重而是肌力。文章分析了在日常生活中影响肌力的因素,包括神经系统障碍、肌肉数量和关节功能障碍等,最后介绍了定量测量这些功能参数的方法和相关设备。

This article revi - ews the relation between cell growth and the stress of it. dernonstrates the contribution of bone stress to bone formation. and describes the biomechanical mechanisms for bone loss, formation and damage. Bone stress directly determines the direction of bone metabolism, and depends on muscle force. not body weight. Muscle force is daily affected by the dysfunction of neural syslem, muscle itself and joints. This article introduces measurement and diagnosis of the dystunction.
