Summary
Patient-specific finite element modeling enhances orthopedic surgery planning and fracture risk assessment. However, further development is required before this advanced engineering tool becomes a routine clinical application.
Area of Science:
- Biomechanics
- Orthopedic Surgery
- Computational Engineering
Background:
- Finite element modeling (FEM) is a long-standing engineering tool for structural analysis.
- Advances in imaging, algorithms, and computing power have significantly improved FEM accuracy.
- Patient-specific finite element models (PSFEMs) can simulate individual anatomy and properties.
Purpose of the Study:
- Critically review current themes in patient-specific finite element modeling of bones.
- Compare the state-of-the-art in bone modeling with clinical applicability requirements.
- Assess the feasibility of integrating FEM into routine orthopedic practice.
Main Methods:
- Review of current literature and state-of-the-art in patient-specific finite element modeling.
- Comparison of existing modeling capabilities with clinical requirements for orthopedic applications.
- Evaluation of the potential for clinical adoption of patient-specific finite element methods.
Main Results:

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
