Study: Metal-on-metal hips impede osteoblast formation (MassDevice)
A study of metal-on-metal hip implants found that the metal ions released when the parts of the cobalt-chromium-molybdenum devices rub against each other were able to penetrate into bone marrow, where they impeded the formation of bone-growing cells.
Metal-on-metal hip implants came under intense scrutiny following the high-profile August 2010 recall of DePuy Orthopaedics’ ASR XL acetabular and ASR hip resurfacing systems. Johnson & Johnson pulled the devices off the market after receiving reports that a higher-than-normal...
