The Furlong® Total Hip Replacement was the first in the world to utilise Hydroxyapatite Ceramic (H-A.C) Coating to promote biological fixation. Since its introduction in 1985 JRI have continued to develop and improve our H-A.C Coating and the way in which it is applied.

One of the most important factors is whether the
H-A.C Coating is applied in atmospheric (APS) or vacuum conditions (VPS). Supravit® is JRI’s VPS H-A.C Coating.

Facts:

  • All JRI implants have been VPS coated since 1993
  • VPS removes oxygen and gas pockets
  • VPS produces a dense homogenous coating, avoiding cracks and preventing delamination
  • Supravit® achieves bond strength in excess of 60MPa
  • Supravit® Coating thickness is 200µm
  • Supravit® adhesive strength is so great that a fully bonded size 10 Furlong® stem could lift the weight of a double decker bus
