“…A three-dimensional CAD model of the pelvis and left femur with hybrid hip arthroplasty prostheses with a 26 mm femoral head (4-U; Nakashima Medical, Okayama, JP (Tanino et al, 2006)) and skeletal muscles crossing the hip joint was developed using CAD software (SolidWorks, Concord, MA) ( Fig. 1).…”

Purpose The aim of this study was to investigate the biomechanics of the pelvis reconstructed with a modular hemipelvic prosthesis using finite element (FE) analysis. Methods A three-dimensional FE model of the postoperative pelvis was developed and input into the Abaqus FEA software version 6.7.1. Mesh refinement tests were then performed and a force of 500 N was applied at the lamina terminalis of the fifth lumbar vertebra along the longitudinal axis of the normal pelvis and the postoperative pelvis for three positions: sitting, standing on two feet, and standing on the foot of the affected side. Stress distribution analysis was performed between the normal pelvis and postoperative pelvis at these three static positions. Results In the normal pelvis, stress distribution was concentrated on the superior area of the acetabulum, arcuate line, sacroiliac joint, sacral midline and, in particular, the superior area of the greater sciatic notch. In the affected postoperative hemipelvis, stress distribution was concentrated on the proximal area of the pubic plate, the top of the acetabular cup, the connection between the CS-fixator and acetabular cup and the fixation between the prosthesis and sacroiliac joint. Conclusions Stress distribution of the postoperative pelvis was similar to the normal pelvis at three different static positions. Reconstruction with a modular hemipelvic prosthesis yielded good biomechanical characteristics.

“…For example, Katoozian et al [11] introduced three-dimensional shape optimization of a femoral prosthesis in which the geometry was defined in terms of longitudinal and cross-sectional shape variables. Kayabasi et al [9,12,13] and Tanino et al [14] followed a similar approach but with different objective functions. Kayabasi's study used maximum von Mises stress of a femoral prosthesis as an objective function to minimize while Tanino's study used the cement's maximum von Mises stress as an objective function.…”
