Povzetek: The programming language Java TM (Sun MIcrosystems, Inc.) is used to produce aset of obejcts that comprise the hip-joint geometry (points, axes, profiles, distances, angles), objects that describe the forces and the stress distribution in the hip-joint articular surfaces (forces, stress), as well as objects that can be manipulated by using Drag and Drop operations in order to simulate changes in the hip-joint geometry (femoral head, femoral neck, greater trochanter and upper part of the femur). Any change in the objects that can be manipulated influences the remaining objects that are currently displayed. Particularly, any change can influence the hip-joint reaction forceand corresponding contact stress distribution. The changes are estimated automatically by using methods that are attached to the specific objects. Digitised profiles of standard antero-posterior radiographs of the hip-joint are used as input to this computer-aided system. A non-homogenous scaling method that is based on a reference model of the hip musculature, is used to prepare data each human subject. These data serve as input to a three-dimensional mathematical model of the hip-joint in one-legged stance, which is used to estimate the value of the hip-joint raction force. Aferwards,the stress distribution in the hip-jont reaction force. Afterwards, the stress distribution in the hip-joint articular surface is calculated by using another three-dimensional model, which takes into account the previouslydetermined hip-joint reaction force, the femoral head radius and thecenter-edge angle of Wiberg.
