CONCLUSION
trunnion corrosion
In this study of THAs with small femoral heads, no indication of severe trunnion corrosion was found. Although we found no significant difference in blood ion levels with the use of Oxinium or metal femoral heads, further investigation of periprosthetic tissues and retrieved implants may give insight to any differences in wear and corrosion mechanism at the trunnion‐head interface between CoCrMo and Oxinium femoral heads.
