Cobalt Toxicity, An overlooked Cause of
Hypothyroidism

Past surgical history included multiple left knee surgery due to trauma nearly 50 years before, lumbar spine surgery nearly 20 years before, total right hip arthroplasty (hip replacement) (with ceramic-on-ceramic bearing) 7 years before and total left hip arthroplasty (with ceramic-on-polyethylene bearing) 5 years before. While the left hip functioned well after replacement, the right hip did not, and it had been painful, produced noise, and been prone to subluxation. Hip X-ray film had showed extensive metallosis around the right hip2 years before (Figure 1). He had undergone revision of total right hip acetabular component with ceramic-on-polyethylene bearing 2 years before. Intraoperatively, large amount of metal debris was noted and cleaned.

Interesting case study. Significant metal debris with 2 ceramic based hip implants particularly on the side with ceramic on ceramic. Also the CoC had squeeking issues.
