In a postmortem study on 50 lower arms of fetuses of the 25th week of gestation and newborn we performed three-point bending experiments to find out the stability of the lower arm after bending to the resulting fracture. Lower arms with intact soft tissue show an elastic behavior when bent from the side until fracture occurs. Applying the loading deflection diagrams we could classify the fractures into three types which differ significantly by means of bending moment, maximal deflection per unit length, and force required.
在一项对25周妊娠胎儿和新生儿的50条下臂进行的尸检研究中,我们进行了三点弯曲实验,以了解下臂弯曲至骨折后的稳定性。软组织完整的下臂在从侧面弯曲直至骨折发生时表现出弹性行为。通过应用载荷-挠度图,我们可以将骨折分为三种类型,它们在弯矩、单位长度最大挠度和所需力方面有显著差异。
