Systemic and local silver accumulation after total hip replacement using silver-impregnated bone cement.

Abstract

In a patient, at revisional Christiansen total hip arthroplasty, silver-impregnated bone cement was used as prophylaxis against deep infection. Five years later the patient developed serious neurological deficits, and the prosthesis was loose. The loose Christiansen prosthesis and the silver-impregnated bone cement were removed and a Charnley prosthesis inserted. Intra-operatively the concentration of silver in fluid drawn from the hip joint was assessed to be about 1000 times the normal serum reference value, and tissue samples from the acetabulum were densely impregnated with silver. During the following 2 years the serum concentration of silver decreased from more than 60 times to 20 times the normal; simultaneously the patient partially recovered from her grave muscle paralysis.
