| Summary: |
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. [COBISS.SI-ID 11208409]
