title: [Biomechanical construction principles of the human hip joint in frontal plane].
abstract: The prognosis of hip joint function is only to determine unsatisfactory on the base of the knowledges of anatomy by means of inspection or angles and distances from X-rays as well as on the base of models known for the biomechanic of hip. The term "normal anatomical" hip structure is analysed with respect to functional biomechanical influences on its macroscopic design in frontal plane. It is shown to interpret the macroscopic hip design as result of an effective arrangement of centre of rotation and muscle forces which a minimum on energy needing for its function. A mathematical equation describes the skeleton-muscle-system hip biomechanically. This new connection between angles and distances as well as first easy consequences are proofed on a-p-hip radiographs of 53 normal adults.
