开发了 11 个月大婴儿的有限元 (FE) 股骨模型，用于评估短距离脚先跌倒和床上跌倒时的骨折风险。儿科材料属性应用于有限元模型。股骨负载源自之前使用儿童代理人进行的跌倒实验，其中跌倒条件（例如跌落高度、冲击表面）发生变化。基于主应力和应变的断裂阈值用于检查断裂的可能性。对于增加的跌落高度和脚先跌落中较硬的表面，峰值应力/应变显着更大。脚先跌倒超过了部分骨折阈值，但并非全部骨折阈值。跌床次数没有超过任何阈值。
A finite element (FE) femur model of an 11-month-old was developed to evaluate fracture risk in short-distance feet-first falls and bed falls. Pediatric material properties were applied to the FE model. Femur loading was derived from previously conducted fall experiments using a child surrogate where fall conditions (e.g. fall height, impact surface) were varied. Fracture thresholds based on principal stress and strain were used to examine potential for fracture. Peak stress/strain were significantly greater for increased fall heights and harder surfaces in feet-first falls. Feet-first falls exceeded some, but not all fracture thresholds. Bed falls did not exceed any thresholds.
