20 hip arthroplasties with a Landos Corail Ti6Al4V stem entirely plasma-sprayed with a 155+/-35 microm thick HA coating were reoperated on after median 6 (2-8) years because of polyethylene wear (10), acetabular loosening (7), instability (2), or infection (1). We took biopsies from the proximal femurs adjacent to the well-fixed stems. Undecalcifled sections were prepared and examined with a light microscope. The biopsies contained median 5 (1.3-16 ) mm metal interface with 54% HA, 32% bone… CONTINUE READING
