Biomedical engineering research has taken another step forward with the development of a synthetic material that mimics human bones. This progress has been possible thanks to the combined use of artificial intelligence, 3D printing and physical stress studies, and could soon replace traditional surgical methods.
Despite theirs irregular architectures, natural materials such as bird bones and feathers manage physical stress incredibly efficiently. Recent research has allowed us to better understand how the structure of these materials influences their ability to modulate stress. Using machine learning algorithms and 3D printing, researchers were able to replicate these features for orthopedic femur restoration.
Challenges in repairing femur fractures
Femur fractures are common, especially among older adults, and often lead to complications such as chronic pain. The conventional method using metal plates and screws can cause loosening and further damage. The new technique, which uses a bio-inspired material, aims to offer a more effective and less invasive solution.
The research work, conducted by Shelly Zhang, professor of civil and environmental engineering at the University of Illinois at Urbana-Champaign, introduces an innovative approach to orthopedic repair. “We started with a materials database and used a virtual growth simulator and machine learning algorithms to generate and optimize a virtual material,” Zhang explained.
Synthetic bones: potential future applications
This technique not only improves bone repair but also has potential applications in various biological implants, where stress manipulation is crucial.
“The method can be applied to different types of materials, such as metals and polymers, thanks to the geometry and mechanical properties we can control,”
Zhang added.
Having a tangible model allowed Zhang’s team to take real-world measurements and test the effectiveness of the material, confirming the possibility of growing synthetic materials in a similar way to biological systems. This approach promises to stimulate bone repair by providing optimal support and protection.
What do you think of this innovation? Could this be the solution we’ve been waiting for to improve orthopedic surgery?
