Diagnosis aseptic necrosis of the femoral head using spiral computer and magnetic resonance imaging and application of mathematical modeling in planning hip replacement operations
This work is devoted to the possibility of using spiral CT and magnetic resonance imaging to visualize areas and staging lesions of the hip with aseptic necrosis of the femoral head. The comparative characteristics of radiological diagnosis was made. Mathematical modeling methods to determine the forces acting in the joint at the elementary movements is described. Depending of the nature forces of the anatomical parameters of the joint and the calculation results of the stress-strain state of the hip and the dependence of the maximum effort from a number of anatomical parameters is shown.
