Human cartilage tissue as a model
The femoral head cover is designed while taking into account different load scenarios. The anatomical differences between men and women will also play a role in the design of the prototype. The material of the cover, a specially developed polyurethane, will have similar elastic properties to human cartilage tissue. The scientists are modifying the polymers to create a biomimetic surface and increase the material's compatibility with the human body.
Process transferable to other medical engineering products
During the development of the femoral head cover, the project partners attach great importance to using materials that conserve resources. Metallic and ceramic materials are therefore not used in the development process. Compressed CO2 is used to purify the plastic product, which can then be removed without leaving any residue. Unlike comparable technologies, the process does not use any organic solvents for polymer modification. High-pressure impregnation is therefore particularly risk-free from an environmental and health point of view and is also suitable for manufacturing other medical engineering products.
Improving orthopedic care
The biomimetic approach contributes to a qualitative and sustainable improvement of medical care in orthopedics and helps arthrosis patients to carry out their daily activities independently again – without having to take on the risks of artificial prostheses.
