利用CT图像研究了一只接受了11年两足行走训练的日本猴子的股骨结构强度。在小粗隆以下和中长度水平处获得横截面特征。分析显示，与普通猴子相比，这种猴子的骨骼强度明显更高。尽管结构强度大大增加，但骨干的弯曲刚度模式与普通猴子相似，而不是人类。小粗隆以下的复位比中长度的复位更明显。这可能表明，稳定髋关节的肌肉活动严重影响了猴子两足行走的股骨近端。
Structural strength of the femur of a Japanese monkey which had been trained for bipedalism for 11 years was studied using CT images. Cross-sectional properties were obtained at below the lesser trochanter level and at mid-length level. The analysis revealed significantly greater strength of the bone compared to ordinary monkeys. Despite greatly increased structural strength, bending rigidity pattern of the diaphysis is similar to that of ordinary monkeys rather than humans. Modifications are more apparent at below the lesser trochanter level than at the mid-length level. This may suggest that the muscle activities, which stabilize the hip joint, severely affect the proximal femur shaft in monkey bipedalism.
