title: [The hydrodynamic components in joints: proof of a membrane-cistern system within the calcified zone of the femur head cartilage].
abstract: The theoretical postulate of a hydrodynamic system for the transmission of forces at the hip joint led to the discovery of a two-membrane system. Within the calcified cartilaginous zone of the femoral head there exists a system of small spaces and cisterns which can only be understood in the postulated sense as an overall acting hydrodynamic system. A correlation between the destruction of the calcified zone, i.e. the hydrodynamic system, and arthrosis is indicated. Ongoing studies and deliberations will help to discover the true model of the transmission of forces and impulses and to solve the problems of treating arthrosis.
