Similarly low blood metal ion levels at 10-years follow-up of total hip arthroplasties with Oxinium, CoCrMo, and stainless steel femoral heads. Data from a randomized clinical trial.

One study showed that the use of Oxinium femoral head decreased the blood cobalt levels versus a cobalt‐chromium‐molybdenum alloy (CoCrMo) femoral head, albeit it did not reach statistical significance. 13 However, a retrieval study showed no difference in the corrosion score between Oxinium and CoCrMo femoral heads. 14 In this randomized clinical study, we wanted to evaluate the blood metal ion levels of Oxinium modular femoral heads at 10 years postoperatively and compare this with patients with the CoCrMo modular femoral head counterpart, and the monoblock stainless steel Charnley prosthesis.
