Key result
Computational fluid dynamics modeling of a 3D femur bone demonstrated that applying external forces of 10N to 500N allows for the measurement of stress distribution and velocity displacement.
Why the study?
The study was conducted to model how femur bone structure changes in response to mechanical stresses that can induce bone formation.
CFD modeling can effectively simulate stress distribution in the femur under varying loads, which may aid in evaluating fracture risk.
Patient-specific 3D femur models enable stress analysis; leaves open clinical utility pending prospective validation.
This research focuses on the aspect of femur bone modeling that will change structure in response to mechanical stresses that can be induced to bone formation. 3D femur bone models are constructed by configuring material and geometric conditions and respecting patients' specific features, providing realistic and performant structural analysis. Using CFD concept, a three-dimensional model of the femur system was established, calculated the level of stress, the distribution of the femur and the magnitude of the transmitted force. This study describes a 3D construction process as well as the generation of the mesh based on a parallel processing of eight processors. Our main contribution revolves around the use of CFD modules to simulate stress measurement in the bone and study their impact in the case of external force exerted with successive values 10N, 50N and 100N
