Segmentation and finite element analysis in orthopaedic trauma

Area of Science:

• Orthopaedic biomechanics
• Computational modeling in medicine
• Surgical planning and simulation

Background:

• Finite Element Analysis (FEA) is indispensable in orthopaedic trauma research and clinical practice.
• This review details the extensive applications of FEA within orthopedic surgery.

Purpose of the Study:

• To review the broad applications of Finite Element Analysis (FEA) in orthopedic surgery.
• To highlight FEA's role in evaluating fracture fixation, implant design, and surgical decision-making.
• To emphasize the importance of FEA in developing personalized surgical plans and implants.

Main Methods:

• FEA involves geometry, segmentation, meshing, material properties, boundary, and contact conditions.
• Utilizes patient-specific data (e.g., CT scans) for accurate biomechanical modeling.
• Combines FEA with cadaveric biomechanical analysis for enhanced validation and in vivo kinematic representation.

Main Results:

• FEA yields critical outcome measures: stress/strain distribution, fracture gap motion, failure prediction, and implant stability.
• Applications include femur/humerus fractures, distal femur planning, tibial plateau fractures, and post-traumatic osteoarthritis.
• FEA aids in fracture risk prediction, construct stability assessment, and guiding surgical strategies.

Conclusions:

• FEA significantly advances orthopaedic trauma research by elucidating biomechanics, fixation, and implant design.
• Integrating FEA with cadaveric analysis improves accuracy and understanding of in vivo kinematics.
• Further validation and clinical integration of FEA are vital for personalized patient care and improved outcomes.
