[Biomechanical aspects of hip dislocation].
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.
