The hip joint forces of sheep and dogs were measured with instrumented endoprostheses and the results were compared with reported data concerning these forces in man. In all animals load directions with 0 to 30 degrees inclinations relative to the femoral axis predominated. The transverse components mostly acted from medio-ventral directions. While the force orientations varied little during each single stance phase, they changed rapidly during the swing phase. Strong inter- and intra-individual differences of load directions were found in all animals. Irregular forces, acting upwards or transverse to the femur, were frequently observed. Maximum joint forces were up to 110% of body weight and depended more on the postoperative time than on the walking speed. Load orientations in the animals were similar to those reported for man. In this regard sheep and dogs appear equally well suited for tests of hip endoprostheses for man.
使用仪器化假体测量了绵羊和狗的髋关节力，并将结果与有关人类这些力的报告数据进行了比较。在所有动物中，相对于股骨轴线倾斜0至30度的负荷方向占主导。横向分量大多从中腹方向作用。虽然在每个单支撑阶段力的方向变化不大，但在摆动阶段变化迅速。在所有动物中都发现了负荷方向存在强烈的个体间和个体内差异。经常观察到向上或与股骨横向作用的不规则力。最大关节力高达体重的110%，更多地取决于术后时间而非步行速度。动物中的负荷方向与人类报告的相似。在这方面，绵羊和狗似乎同样适合用于人类髋关节假体的测试。
