Abstract
Background/aims: Cobalt and chromium are released from MOM hips and their precise nature (ions/particles) is not known. Their distribution in serum, plasma, and whole blood may help to determine their nature.
Methods: We measured cobalt and chromium concentrations in plasma, serum, and whole blood samples of patients with resurfacing MOM hips.
Results: We found that chromium concentration was highest in plasma, followed by serum and whole blood. Chromium and cobalt concentrations were higher in serum and plasma, compared to whole blood.
Conclusion: We, therefore, suggest that in future cobalt and chromium concentrations shall be reported using plasma samples.
Keywords: Chromium; Cobalt; Metal ions; Plasma; Serum.
