羊和狗的髋关节力测量仪器内假体，结果与这些力量在人的报道数据进行比较。在所有动物加载方向为0到30度。相对于股轴的倾斜占主导地位。横向成分主要从中腹方向起作用。在每个阶段的立姿阶段，力的方向变化不大，但在摇摆阶段，力的方向变化很快。所有动物在负荷方向上均存在强烈的个体间和个体内差异。经常观察到向上或横向作用于股骨的不规则力。最大关节力可达体重的110%，并且更多地取决于术后时间而不是步行速度。动物的负荷方向与人类相似。在这方面，羊和狗似乎同样适合于测试人类的髋关节内假体。
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.degree. inclinations relative to the femoral axis predominated. The transverse components mostly acted from medioventral directions. While the force orientations varied little during each stage stance phase, they changed rapidly during the swing phase. Strong inter- and intraindividual 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.
