An experimental model using immature bovine femora and tibiae was used to determine the varying patterns of failure in and around the physis when the direction of stress was varied. Compression, tension, shear, and torque were individually applied. The results showed that the histologic failure pattern did vary with each type of applied load. Compression resulted in failure in the zone of provisional calcification and the metaphysis rather than the previously hypothesized germinal zone. Tension loads caused failure in the upper zone of columnation. Failure in between the upper zone of columnation and lower zone of hypertrophy was caused by shear loads. Torque resulted in failure through all zones.
使用未成熟牛的股骨和胫骨建立了一个实验模型，以确定当应力方向改变时，生长板及其周围的不同失效模式。分别施加压缩、拉伸、剪切和扭矩。结果表明，组织学上的失效模式确实因每种施加的载荷类型而异。压缩导致临时钙化区和干骺端失效，而非先前假设的生发区。拉伸载荷导致柱状区上部失效。柱状区上部和肥大区下部之间的失效是由剪切载荷引起的。扭矩导致所有区域失效。
