The computer system
Viprecox (Vis et pressus in coxa, Forces and pressure in the hip joint) was
developed for estimation of some geometrical parameters of the human pelvis and
femur and calculation of the stress distribution in the hip joint articular
surface. For this purpose the object-oriented programming language Java (Sun
Microsystems, Inc.) was used. Basic data about the patientsas well as digitized
profiles of standard antero-posterior radiographsare used as input to the
computer system. An alternative procedure was developed for automatical
determination of digitized profiles directly from antero-posterior radiographs
(the computer system Active Contours). The system Viprecox automatically
estimates some important points, distances and angles that comprise the geometry
of the pelvis and the femur. By using these parameters the system calculates and
graphically represents the hip joint reaction force and the stress distribution
in the hip joint articular surface in the frontal plane of the body. The
calculation of the forces and the stressdistribution acting on the hip joint is
based on existing three-dimensional mathematical model of the hip joint reaction
force and three-dimensional model of stress distribution in the hip joint
articular surface. Additionally, the system allows visualization of the changes
in the stress distribution when appropriate changes in the geometry of the hip
joint occur, with respect to the implemented models. The functioning of the
computersystem was checked by calculating some geometrical parameters of the
pelvis and the femur and the maximal stress in the hip joint articular
surface(pmax) for 81 patients (37 male and 44 female) that were operatively
treated for acute medial fracture of the femoral neck by implantation of hip
endoprosthesis. (Abstract truncated at 2000 characters.) [COBISS.SI-ID 1901396]
