Fracture pattern projection on 3D bone models as support for bone fracture simulations

Area of Science:

• Computational biomechanics
• Medical imaging
• Forensic science

Background:

• Generating realistic bone fracture models is challenging, often requiring real-world fractures or complex medical image processing.
• Existing methods lack the ability to create specific fracture patterns on demand.

Purpose of the Study:

• To develop a method for designing specific fracture patterns.
• To project these patterns onto 3D geometric bone models for virtual fracturing.
• To validate the accuracy and applicability of the projected fracture patterns.

Main Methods:

• Expert-generated fracture patterns with geometrical and topological information were created.
• These patterns were projected onto 3D models of long bones (femur, humerus, ulna, fibula).
• Validation involved expert review and forensic analysis for impact-induced fractures.

Main Results:

• Successfully projected diverse fracture patterns onto various 3D bone models.
• Expert validation confirmed correct pattern fit despite bone irregularities.
• Forensic validation provided feedback for refining fracture patterns based on impact analysis.

Conclusions:

• The developed method accurately projects fracture patterns onto 3D bone models.
• Utilizing topological information establishes a foundation for guided virtual bone fracturing.
• This approach enhances the creation of realistic fracture models for research and analysis.
