In order to verify the existence of tension and compression forces from the cortical surface of canine femora, rosette strain gauges and a radio telemetry system were used to observe the animals during normal locomotion. Surface strain measured from the lateral cortical surface was consistently in tension whereas surface strain measured from the medial cortical surface was in compression. This data supported in vitro work which showed that eccentric loading of bone results in the convex side of bone being in tension and the concave side of bone being in compression.
为了验证犬股骨皮质表面张力和压力的存在，在正常运动过程中使用应变片式应变计和无线电遥测系统对动物进行观察。从外侧皮质表面测得的表面应变始终处于张力状态，而从内侧皮质表面测得的表面应变则处于压缩状态。该数据支持了体外研究结果，即骨骼的偏心载荷会导致骨骼凸面处于张力状态，凹面处于压缩状态。
