Abstract

Ceramic bearing surfaces are being increasingly used in young patients undergoing total hip arthroplasty. However,
failures have been reported including fractures even with the newer third generation ceramics. The recommended
treatment for fracture of ceramic bearing surfaces is complete synovectomy and revision total hip arthroplasty.
However, disappointing results have also been reported with this approach. The residual ceramic particles may lead
to complications. We report a fatal case of cobalt toxicity leading to cardiomyopathy secondary to the catastrophic
failure of a Cobalt-Chrome femoral head, which followed the revision of a fractured ceramic-on-ceramic total hip
arthroplasty.
Level of evidence: IV
