Finite Element Modeling of the Human Wrist: A Review

Area of Science:

• Biomechanics
• Computational modeling
• Orthopedic research

Background:

• Understanding wrist biomechanics is crucial for diagnosing and treating wrist joint conditions.
• Finite element method (FEM) offers advantages over experimental methods for analyzing complex biomechanical systems.
• Inconsistent methodologies in published FEM studies hinder the integration of findings.

Purpose of the Study:

• To systematically review the application of FEM in wrist biomechanics research over the past decade (2012-2022).
• To identify trends, common practices, and limitations in FEM modeling of the wrist joint.

Main Methods:

• A comprehensive literature search was conducted across major scientific databases (EBSCO, Research4Life, ScienceDirect, Scopus).
• Studies published between 2012 and 2022 focusing on FEM analysis of the wrist were included.
• Twenty-two relevant studies were selected for detailed review and synthesis.

Main Results:

• FEM applications in wrist biomechanics cover general mechanics, pathology, and treatment, exhibiting significant heterogeneity.
• Most models incorporate bone structures, but fewer include critical soft tissues like cartilage and ligaments.
• The dynamic influence of wrist tendons on joint mechanics is infrequently represented in current FEM models.

Conclusions:

• The existing body of literature on FEM for wrist biomechanics is incomplete due to the inherent complexity of the joint.
• Developing standardized strategies and advanced modeling techniques is essential for creating more accurate and comprehensive wrist models.
• Improved model fidelity will enhance our understanding and clinical management of wrist pathologies.
