The authors wanted to study the effect of non-physiologic muscular forces on growing rat bones. 35 animals were submitted to a total extirpation of the femur, 40 animals served as control group. They were killed immediately, six, twelve, or 24 weeks later, respectively. The results determined by macroscopic X-ray and fluorescence microscope examination are identical. As opposed to the control tibiae, the tibiae exposed to a greater load showed an increased bone density, increased ventral and lateral annexes, above all within the proximal third, and a torsion apparent in the cross-section. The less loaded tibiae showed a smaller bone density, increased medial and lateral annexes, above all within the proximal third, and a torsion apparent in the cross-section. The results are explained by the varying action of pressure and muscular forces and compared to those achieved by other authors.
作者们想要研究非生理性肌肉力量对生长中的大鼠骨骼的影响。35只动物接受了股骨完全切除手术，40只动物作为对照组。分别在术后立即、6周、12周或24周将它们处死。通过宏观X射线和荧光显微镜检查得出的结果是一致的。与对照胫骨相比，承受更大负荷的胫骨骨密度增加，腹侧和外侧附件增多，尤其是在近端三分之一处，并且在横截面上有扭转现象。负荷较小的胫骨骨密度较小，内侧和外侧附件增多，尤其是在近端三分之一处，并且在横截面上有扭转现象。这些结果通过压力和肌肉力量的不同作用得到了解释，并与其他作者所取得的结果进行了比较。
