Influence of growth plate morphology on bone trabecular groups, a framework computational approach

Area of Science:

• Orthopedics
• Biomechanics
• Developmental Biology

Background:

• Growth plate morphology changes during development, impacting long bone epiphysis stress distribution.
• Understanding this relationship is crucial for bone health and preventing skeletal disorders.

Purpose of the Study:

• To investigate the correlation between growth plate morphology and trabecular bone patterns.
• To explore the biomechanical implications of growth plate morphology on bone strength and failure prevention.

Main Methods:

• Utilized a finite element model for analysis.
• Examined trabecular patterns in the femoral epiphysis and calcaneus bone in two medical cases.

Main Results:

• A significant correlation was found between growth plate morphology and the formation of main trabecular groups.
• Increased density in peripheral high-shear stress zones may prevent shear failure, aligning with clinical observations in conditions like slipped capital femoral epiphysis and Sever's disease.

Conclusions:

• Growth plate morphology plays a key role in determining trabecular bone patterns and stress distribution.
• Further research into growth plate morphology's impact on bone remodeling could lead to new preventive strategies for bone disorders.
