Sub-study of Alberta HIP Examining Metal Particles in Blood
A sub-study of Alberta HIP is examining levels of metal particles, called ions, released into the blood as the metal surfaces in the hip resurfacing device wear. The levels and long-term health consequences of metal ions in the blood associated with metal-on-metal resurfacing are unknown. The ions consist of chromium and cobalt, the metal components in the implant.
A group of 174 MOM resurfacing patients in Alberta HIP consented to have blood tests for metal ion levels.
