June 23, 2016 — Metal-on-metal hip implants release tiny particles of metal that can penetrate into bone marrow and stop the formation of bone-growing cells, according to a new study.
Researchers found that metal-on-metal hip implants release cobalt and chromium particles that contribute to bone loss, leading to premature revision surgery.
The study was published in Biomaterials by researchers in Germany, where approximately 220,000 total hip replacements are performed every year.
When the moving parts of a metal-on-metal hip implant grind together, nanoparticles of chromium and cobalt are released into the body.
Dissolved metal ions were shown to reach the bone marrow and interfere with mesenchymal stromal cells (MSCs), which grow into cells called osteoblasts that mineralize bones.
Patients with elevated levels of metal in their bone marrow had less ability to make osteoblasts. The researchers warned that the continued use of metal-on-metal hip implants “needs critical reconsideration” with risks that clearly exceed the benefits.
Metal-on-metal hip implants have been under intense scrutiny since the high-profile recall of the DePuy ASR in August 2010.
The ASR has been linked to a 40% five-year failure rate. Many other studies have confirmed that metal-on-metal hip implants have higher rates of failure and revision surgery than ceramic and plastic designs.
