Cobalt and chromium ion levels are elevated post
metal-on-metal hip resurfacing arthroplasty. They remain
elevated at 2 years post-op (median serum cobalt 1.6 ug/l
and chromium 3.3 ug/l).
Cobalt and chromium ion levels become elevated following
insertion of a metal on metal hip prosthesis. Few
studies have prospectively assessed ion levels following
hip resurfacing … Read the rest
