Blood Metal Ions Tied to Failed Hip Replacement, Resurfacing
Raised levels of blood metal ions are associated with failed metal-on-metal hip resurfacings and total hip arthroplasties, according to a study published in the July 2 issue of The Journal of Bone & Joint Surgery.
The researchers found that patients with failed arthroplasty had significantly higher blood cobalt and chromium ion levels than patients with non-failed arthroplasty (P < 0.01).
