Investigation in cadaver femora of the relationship between the shape or size of a hole made in the cortex and the breaking strength of the bone revealed that of the shapes studied, an oblong hole with rounded ends afforded the greatest residual strength. Furthermore, we found that increasing the width of the hole caused a significant reduction in strength, while increasing the length did not.
对尸体股骨中皮质骨上所开孔的形状或大小与骨的断裂强度之间关系的研究表明，在所研究的形状中，两端呈圆形的椭圆形孔具有最大的残余强度。此外，我们发现增加孔的宽度会导致强度显著降低，而增加长度则不会。
