Abstract
- Introduction: Metal toxicity from metal-on-metal hip replacements is now well documented and several large series have reported local reactions. Although less common, there are reports of similar reactions from failed ceramic liners. Systemic effects documented in literature have been grouped into cardiac, neuro-ocular and thyroid signs.<br />Methods and Results: We report a case of a patient who had revision for fractured ceramic liner to metal on polyethylene. Third body effect of the ceramic particles led to wear through of the poly liner and the head directly articulating with metal shell. He developed cardiac and neurological features of cobalt toxicity in addition to extensive soft tissue destruction. Revision of the bearing surfaces and synovectomy led to clinical improvement and fall in metal ion levels.<br />Conclusions: We recommend 2-stage revision in such situations and close monitoring of all these patients.
