Acetabular Bone Defect in Total Hip Arthroplasty for Crowe II or III Developmental Dysplasia of the Hip: A Finite Element Study

Figure 1

(a) The model of acetabular bone defect in total hip arthroplasty for Crowe II or III DDH. (b) The uncoverage area gradually increased by the length of the arc AC, and the angle denoted the central angle of the uncovered portion above the cup. Angle was formed by the crossing of line OA and OC. (c) Fixed constraint boundary conditions were assumed at the sacroiliac joint and pubic symphysis. (d) Simulated vertical reaction load was applied from the bottom of the femur.
