Development of a test system for evaluation of hip protectors to prevent hip fracture

本文阐述了髋部摔伤的发生机制和髋关节保护装置对髋部骨折的保护作用，并据此建立了髋关节保护装置的测试系统。在此基础上，我们设计并制造了测试系统，并对我们开发的一种保护器和市场上的几种保护器进行了评估。除此之外，我们还进行了分析，评估了臀部跌倒导致髋部骨折的风险，发现背部跌倒可能比走路时摔倒更危险。为了获得准确的模拟结果，我们还对肌肉骨骼肌损伤特性的实验结果进行了观察和整理，并建立了肌肉的本构模型。

The mechanism of hip fracture by fall and the effects of hip protector on the protection of hip fracture are elucidated for developing a test system to evaluate a hip protector. Based on the results, we design and manufacture the test system, and evaluate a protector developed by us, and a few protectors commercially available in the marketplace. In addition to these, we perform the analysis to evaluate the risk of hip fracture by backside fall, and find that the backside fall may be more dangerous than the fall under walking. To obtain accurate simulation results we also observe and organize our experimental results on damage properties of musculoskeletal muscle, and formulate constitutive models of the muscle.
