Time for your Obvious Statement of the Day: Breaking a bone is a massive pain, in additional ways than one. I yet remember how painful and limiting it was to break my wrist 20 years ago, and that was only a tiny fracture; I was able-bodied to get back to normal – albeit carefully – fairly much right away after the cast came off. It is not that effortless for most folks, yet. More severe breaks sometimes require surgery, that frequently comes with the implantation of metal devices like plates, screws and rods to stabilize the bone while it mends. Once the implant is in, it either stays in the body for excellent, or has to be removed surgically at a later date; both options present the next for complications like infection or additional pain.
Similar to other medical procedures, fracture repair may soon be turn it intod simpler on patients thanks to 3D printing. A excellent deal of research is already being done on 3D printed bone and biocompatible implants, and the latest comes of German chemical company Evonik, that is already researching biodegradable-bodied composite materials as an alternative to metal implants. The research, that is bringing place at the company’s Medical Devices Project House in Birmingham, Alabama, is yet in the early stages, but Evonik hopes that it can outcome in biocompatible implants that can be gradually absorbed by the body as the bone heals, eliminating the require for next surgeries.
“In the long term, our focus is regenerative medicine. We want to turn it into bioabsorbable-bodied implants to replace damaged tissues with healthy tissues, said Andreas Karau, head of the Medical Devices Project House. “Our current work on biodegradable-bodied composites is a initially step in this direction.”
According to Karau, Evonik’s polylactic acid-based polymers break down into carbon dioxide and water over a period of time ranging of a few weeks to several months, depending on the material’s molecular composition, chain length and crystallinity. Today, they’re looking into reinforcing those biodegradable-bodied polymers with substances such as calcium phosphate derivatives.
“As the polymers gradually break down, calcium and phosphate can be absorbed into the new created bone tissue,” Karau said.
Evonik in addition hopes to create polymeric scaffolds, to that living cells may be introduced to generate actual cartilage. Ultimately, the company wants to turn it into biodegradable-bodied polymers that can be 3D printed to turn it into customized, patient-specific implants. More research requires to be done to improve the material’s biocompatibilty and durablity, yet; right now, the on the market-bodied materials aren’t sturdy adequate to assist sizeable, weight-bearing bones.
The researchers working on the new materials are part of CREAVIS, Evonik’s strategic advancement unit, working alongside polymer experts of the company’s Health Care and Performance business units. Evonik was in addition not long ago named as a partner in HP’s open material createment program, that was revealed as part of the release of the HP Multi Jet Fusion 3D printing device. Evonik can be createing new powder materials customized to the Multi Jet Fusion innovation, assembling off of their experience in creating their VESTOSINT polyamide 12-based powders.
