ATLANTE

Press-fit acetabular cup, with blanked-off screw hole

ATLANTE acetabular cup is a rigid, press-fit, cementless acetabular cup. Its special feature is the screw holes that remain blanked-off, if screws are not used.

This cup, thanks to its specific metal-back, offers a tight interface (if no screw is used) to polyethylene remains to avoid the risks of osteolysis of the bone receiver.

Indications

ATLANTE acetabular cup is usually used in surgery of :

first intention THP due to coxarthrosis, dysplasia, or polyarthritis...

It can also be used in case of :

acetabular revision

Concept

ATLANTE was developed to limit to the maximum the release and the migration of polyethylene particles to the bone receiver.

With this intention, this cotyle is provided with blanked-off screw hole, if the screws are not used.
The polar hole is blanked-off, once the impaction carried out with a polar screw dedicated for this purpose.
The inner surface of the metal-back acetabular cup has a mirror finish, to avoid all polyethylene wear.

Product characteristics

Metal-back

The metal-back of ATLANTE acetabular cup is made of TA6V4 titanium alloy.
It is coated with T40 titanium and a coating of hydroxyapatite on its external face to promote secondary fixation.

It is covered with titanium T40 projection for a better secondary fixing.
Press-fit is performed thanks to a flare and an equatorial macrostructures.

Blanking-off the screw holes ensures a perfect seal of the area in contact with the bone when it is installed as a press-fit unit without screws.

The ATLANTE acetabular cup comes in a range of sizes from 46 to 68 mm, by step of 2mm.

PE & alumina inserts

The UHMWPE polyethylene insert and alumina inserts has a flange and a notched fixation system with 12 outgrowth guaranteeing perfect stability.

These crenels allow the orientation of the posterior wall by step of 30°.
