Significance of Lateral Pillar in Osteonecrosis of Femoral Head

The lateral pillar of the femoral head is an important site for disease development such as osteonecrosis of the femoral head. The femoral head consists of medial, central, and lateral pillars. This study aimed to determine the biomechanical effects of early osteonecrosis in pillars of the femoral head via a finite element (FE) analysis.A three-dimensional FE model of the intact hip joint was constructed from the image data of a healthy control....
