Abstract
A 3−D reconstruction method based on CT scans was used to compute the femoral head coverage for dysplasic hips prior and after reconstruction surgery. The triple osteotomy technique was used to “reorient” the acetabulum of severe dysplasic hips. After 3−D reconstruction of the pelvis and the medial part of the femur, a finite element model (FEM) was created which allowed for a static analysis contact study to quantify the contact pressure distribution in the hip joint. After 3D reconstruction of the pelvis and the medial part of the femur, using a specialized software MIMICS (Materialise), a finite element model (FEM) was created with ABAQUS/CAE (Abaqus Inc.). A material assignment was performed for each element. A solution was found to account for the presence of the cartilage layers. The FEM allowed for a static and dynamic analysis contact study to quantify the contact pressure distribution in the hip joint
