The stress distribution in the subluxated hip joint is analyzed by means of a two-dimensional computer model. Luxation becomes manifest if the action line does not intersect with the contour of the socket. Pathological stress with overloading of the bone and cartilage tissue appear if the articular resultant force is shifted towards the acetabular edge. The important parameter is the CE angle. The coxa valga per se has no pathological meaning as long as the femoral head is covered sufficiently by the acetabular roof.
通过二维计算机模型分析半脱位髋关节的应力分布。如果作用线不与髋臼轮廓相交，则会出现脱位。如果关节合力向髋臼边缘偏移，则会出现骨和软骨组织过载的病理性应力。重要参数是CE角。只要股骨头被髋臼顶充分覆盖，髋外翻本身就没有病理意义。
