A unique double mobility cup: completely in trabecular titanium
for an high primary stability and
an hypoallergenic solution
Product range: 14 sizes press-fit
(Ø 38-64mm)

The ACORN TRASER® cup is a unique dual mobility solution.
Entirely made of titanium alloy by 3D printing technology, it combines two innovative technologies developed by Permedica – TRASER® and BIOLOY® to promote a stable primary press-fit anchorage and an optimal tribology for the coupling with the joint insert.
The ACORN TRASER® cup is also a hypoallergenic solution.

TRASER® structure
The TRASER® randomized trabecular structure surface in contact with the bone promotes an excellent primary press-fit anchorage and osseointegration [1].

Inner surface BIOLOY® coating
The BIOLOY® TiNbN coating on the inner surface of the cup guarantees an optimal tribology for the coupling with the joint insert.

Dual Mobility inserts
Dual Mobility inserts, available with 22 and 28mm inner diameter, are designed for a perfect coupling with the inner surface of every cup sizes, providing the highest articular stability.
They are made of UHWMPE (GUR1020) without calcium stearate, available also with Vitamin E VITAL-E® and VITAL-XE® version (cross linked).
