Abstract
During the development of an osteoarthritic hip joint, osteophytes, cysts as well as arthrosis originate on the contact boundary between the femoral head and the acetabulum in highly loaded human joints. The purpose of proximal femur osteotomy is to bring the femoral head into a new position inside the acetabulum.
The corrective options of intertrochanteric osteotomy most frequently used in orthopaedic practice are valgization, varization, displacements, oblique displacements, lateralization, extension, rotation or shortening of the shaft. The present widespread tomographic measurement methods, such as computer tomography (CT), magnetic resonance imaging (MRI) and 2D or 3D reconstruction involve the simulation of surgical problems of osteotomy, as well as the simulation of the reconstruction of the function of the hip joint after the operation.
The results of numerical modelling of osteotomy concerning contact problems, will be presented in the contribution
