MOSCOW (MRC) -- Evonik is conducting research into biodegradable high-strength composites, which could potentially replace metal in implants used for the internal fixation of fractured bones, said the company on its site.
Implants play a key role in supporting bones until they heal. Today’s metallic devices typically remain in the body for the rest of the patient’s life or require additional surgery for removal. By contrast, devices made with Evonik’s new composites will be absorbed by the body gradually once the bone healing process has taken place. These materials consist of polymers and of substances that naturally occur in bones. Evonik’s research is still in its early stages - however, the possible benefits for patients are already clear. Patients will no longer need to undergo additional surgical procedures to remove the implanted devices. Specific device designs may also help bones regenerate faster.
The project is one of a number currently being conducted at the Medical Devices Project House in Birmingham, Alabama, USA, which employs a team of more than 20 experts. Its mission is to develop new medical technology solutions and materials, with a particular emphasis on implants.
Medical device manufacturers use Resomer polymers marketed by Evonik’s healthcare business line to make bioabsorbable screws, pins and small plates. These are primarily used for torn ligaments in the knee or shoulder, and for fixation of smaller bones in fingers or the face.
As MRC informed earlier, Evonik Industries recently started operating a thin-film composites plant to coat membranes for use in organic solvent nanofiltration and gas separation at its Marl site in Germany.
Evonik, the creative industrial group from Germany, is one of the world leaders in specialty chemicals. Its activities focus on the key megatrends health, nutrition, resource efficiency and globalization. Evonik benefits specifically from its innovative prowess and integrated technology platforms. Evonik is active in over 100 countries around the world.
