A finite element analysis model to support ligamentum teres function.

ABSTRACT: The function of the ligamentum teres (LT) remains debated, particularly its role in limiting motion. The aim of this study was to use finite element analysis to assess LT stress during hip movements, which included external rotation with flexion. A 3D model of the hip joint, including the femoral head and LT, was constructed from magnetic resonance imaging data using 3D Slicer. The models were imported into Ansys SpaceClaim 2022R1 for refinement and assembly. The von Mises stress in the LT was extracted during six hip movements: external rotation, internal rotation, abduction, adduction, flexion, and extension. LT stress response was also extracted during external rotation at hip flexion angles of 0°, 30°, 60°, and 90°. The results found there was a sharper increase in LT stress during mov
