[Progression on finite element modeling method in scoliosis]

Area of Science:

• Biomechanical Engineering
• Orthopedic Surgery
• Medical Imaging

Background:

• Scoliosis is a complex spinal deformity with challenging pathogenesis and limited biomechanical study due to specimen acquisition difficulties.
• Advancements in computer technology have enabled the development of sophisticated finite element models (FEM) for human spine research.
• FEM is increasingly vital for understanding scoliosis, designing braces, and selecting surgical interventions.

Purpose of the Study:

• To review national and international literature on finite element modeling methods for scoliosis.
• To provide a comprehensive overview of the process of establishing high-quality finite element models of the spine.
• To guide researchers in selecting appropriate modeling methods based on their specific research objectives.

Main Methods:

• Literature review of finite element modeling techniques in scoliosis research.
• Analysis of methods for data acquisition (e.g., imaging).
• Examination of geometric model creation, material property assignment, parameter setting, and model validation.

Main Results:

• Finite element modeling is a maturing technology providing strong support for scoliosis research.
• Establishing high-quality finite element models is fundamental for accurate analysis and future studies.
• Various methods exist for finite element modeling, necessitating careful selection based on research goals.

Conclusions:

• Finite element modeling has become an indispensable tool in the biomechanical study of scoliosis.
• The review synthesizes current approaches to finite element modeling in scoliosis, covering key stages from data acquisition to validation.
• Choosing the right modeling strategy is critical for successful biomechanical analysis of spinal deformities like scoliosis.
