BAE Systems and the Office of Naval Research have jointly developed a new type of artificial bone capable of supporting new bone growth and simultaneously porous enough to be absorbed by the body.
In current orthopedic implant materials, the affected bone is in danger of becoming too weak before substantial mass loss of the implant. With use of current materials such as copolymerized polylactic and polyglycolic acids (PLA/PGA) as bone fillers, patients may find bones are too weak to carry any
load long before significant amounts of bone have grown to replace the eroded prosthesis .
The ceramic coated biocompatible plastic would be broken down over the next 18 months by the body after bone cells had filled the pores in the ceramic. All that would remain of the implant would be some of the original polymer core encased in sturdy bone tissue.

Like that silicon in the 70’s led to the modern information technology industry,the development of advanced materials will fuel many of the emerging industries that will address challenges in energy,defense,ceramic, health care and other areas.
Prepared by an ad hoc group of the National Science and Technology Council, this initiative proposes a new national infrastructure for data sharing and analysis that will provide a greatly enhanced knowledge base to scientists and engineers designing new materials. Read More…
