Scientists at two British universities are working on a new artificial hip that would stimulate bone growth, essentially creating a new hip in each patient. The technology would eliminate dangers from metal-on-metal hip replacements like the BioMet M2a Magnum, including tissue damage and the need for revision surgery.
The research involves stem cells, which attach to a plastic material and in turn generate into new bone growth. As the plastic creates bone growth, it disintegrates to leave new, healthy bone in its place. Unlike many of the currently recalled hip replacements, the natural bone hip replacement would last for a lifetime.
The BioMet M2a Magnum is one of several metal-on-metal hip replacements to come under scrutiny for failing and causing serious complications. A 2011 study found that patients with a m2a Magnum hip replacement had a revision surgery rate of 7.2%, with patients complaining of pain, hip fretting, corrosion and metal poisoning from toxic levels of chromium and cobalt in the bloodstream.
