EcoFit® EPORE® Cup

EPORE® is a highly porous structure made of titanium alloy (TiAl6V4) - an excellent material for use as a porous in-growth structure as it is biological inert, ductile, corrosion resistant and also has a high fatigue strength. The structure has a low modulus of elasticity which is similar to that of bone and is characterised by rods of 330 to 390µm diameter which are arranged in a way that mimics cancellous bone.

EcoFit® EPORE® cups have a central hole, in the acetabular base, for attaching the introducer which allows a secure and controlled implant impaction. Once the cup is seated, this central hole can be covered with a central screw plug. The EcoFit® EPORE® cup also has between three and seven pre-plugged holes which can be removed, even when the cup is in-situ, for the insertion of supplementary cancellous screws to enhance primary stability if required. These screws can be angled up to 15°. The cup is also available without additional holes (EcoFit® EPORE® NH) – only the impaction hole and with TCP-coating (Bonit®).

A 32mm articulation is possible with a 46mm diameter cup and a 36mm articulation is possible from a 50mm cup. This applies to implacross® and to BIOLOX® delta liners.

In addition to polyethylene and ceramic inserts the EcoFit® insert consisting of CoCrMo is also available. Together with the PE heads of the EcoFit® 2M system it enables a tripolar treatment from size 50mm.
