You are in: Main Page / Medical articles / News / Brand New Wooden Bones
Scientists will be able to build bones from old bits of wood. Brand new wooden bones can be a revolutionary invention.
These wooden bones can be used as grafts in people who demand to replace their skeleton parts in an injury or disease. Doctors want to use fragments of the fake bone to boost body's own renewal processes. Human's organism is able to grow replacement bones, but new developing tiny cells need to have something to cling to. Italian scientists decided to experiment with wood because it resembles the structure of the bone.
Especially red oak is made of such cellular make-up which makes a great support for cells that grow during the reconstruction. In Britain, thousands of people need hospital treatment and their treatment involve reducing the fracture and beginning the natural process of healing by aligning the ends of the broken bone.
However, breaking bones often demand more dramatic measures, e.g. steel plates or bone grafts which link the ends of the bones. Surgeons often remove bits of bone from pelvis which doesn't have a long-lasting effect on patients' lives but it requires surgery and may leave a patient with significant pain. Recent years brought about the use of bone implants, metal or ceramic ones but they lack the texture of natural bones and they don't bond with the skeleton. Therefore wood can be a better solution.
To check how wood works the scientists put the wood in the heat to get rid of all "living" material. After that, they receives charcoal which was sprayed with calcium-based solution. Then, the wood was exposed to high levels of oxygen and carbon dioxide and put in the water resembling salt found in bone. The results were astonishing, the wood was coated with a substance that makes about 90 percent of human bone - hydroxyapatite. It can interact with the natural bones and create a bond. The wood would eventually break down and leave the healthy bone in desired place.
