Background:

Traditional bone defect treatments face limitations.
Bone scaffolds offer a promising alternative with reduced risks.
Optimizing scaffold parameters like porosity and pore size is challenging.

Purpose of the Study:

To propose a bionic bone scaffold design method using a diffusion model.
To mimic natural cancellous bone properties for improved scaffold design.
To address limitations in current scaffold parameter optimization.

Main Methods:

Developed a classifier-free conditional diffusion model trained on porcine cancellous bone Micro-CT images.
Generated personalized 2D bone-like images with tunable microstructures.
Stacked 2D images to create 3D scaffolds and performed fluid dynamics, mechanical, and biocompatibility tests.

Main Results:

Precisely controlled porosity (50-70%), pore size (468-936 μm), and trabecular thickness (156-312 μm).
Scaffolds demonstrated robust permeability, fluid shear stress, adjustable Young's modulus and compressive strength, and viscoelastic properties.
Scaffolds exhibited good biocompatibility, meeting clinical implantation requirements.

Conclusions:

The diffusion model enables personalized scaffold design for bone defect repair.
The method effectively mimics natural bone microstructures and properties.
Promising results indicate potential for clinical application in treating large bone defects.
