Primaro Cup

Ti6Al4V (ISO 5832-3), cementless

The Primaro cup is a modular acetabular hip cup made of a biocompatible TiAl6V4 (ISO 5832-3).  The Cup is available in three different variants. One version is available with a rough blasted surface.  Besides that we offer the Primaro Cup with a Titanium Plasma Spray (TPS) coating and a TPS+BONIT coating for cementless anchoring in the acetabulum. The size spectrum ranges from 44 to 68 millimeters outer cup diameter.

The Primaro cup is available with screw holes, that are are closed when delivered. If required, self-tapping flat-head screws are available to improve the fixation of the outer shell in the acetabulum. Position markings on the plane surface of the cup allow the screw holes to be aligned in the cranio-lateral direction.

Depending on the inlay type, sizes 28, 32 and 36 millimeters are available to hold femoral heads.

Inlays made of UHMWPE (ISO 5834-2) as well as ELEC plus inlays made of ceramic and BIOLOX® delta inlays made by CeramTec (ISO 6474-2) can be considered as sliding partners with the femoral head.

We offer inlays as UHMWPE standard and XL-PE. The XL-PE inlays are made of highly cross-linked UHMWPE. A dysplasia variant of the polyethylene inlays is also available.
