For a complete biostatical analysis of the hip joint, it will be necessary, besides determining the load, to calculate the extent of strain. In Part I of this article, we described the fundamentals of an improved calculation method which allows its clinical application. In the present second part of the article, a more sophisticated method of calculating the maximal pressure is explained. This takes into account, in particular, the position of the centre of the head of the femur to level of access to the acetobulum, the anteversion of the acetabulum, and the width of the interarticular space. The biomechanical method of analysis is supplemented by the description of a method to calculate the distribution of pressure in the hip joint. In an appendix, the mathematical connections of this calculation are described in detail.
对于髋关节进行完整的生物统计学分析，除了确定负荷外，还需要计算应变程度。在本文的第一部分，我们描述了一种改进的计算方法的基本原理，该方法可应用于临床。在本文的第二部分，将解释一种更复杂的计算最大压力的方法。该方法特别考虑了股骨头中心相对于髋臼入口平面的位置、髋臼的前倾角以及关节间隙的宽度。通过描述一种计算髋关节压力分布的方法，对生物力学分析方法进行了补充。在附录中，详细描述了该计算的数学关系。
