The ACORN TRASER\u00ae<\/sup> cup is a unique dual mobility solution.<\/p>\n

Entirely made of titanium alloy by 3D printing technology,<\/strong> it combines two innovative technologies developed by Permedica – TRASER\u00ae<\/sup> and VITAL-B\u00ae<\/sup> to promote a stable primary press-fit anchorage<\/strong> and an optimal tribology<\/strong> for the coupling with the joint insert.<\/p>\n

The ACORN TRASER\u00ae<\/sup> cup is also a hypoallergenic solution.<\/strong><\/p>\n<\/div>

High primary stability<\/p>\n

The cup has an hemispherical geometry with polar deflection<\/strong> and circumferential radial grooves<\/strong> to guarantee an effective press-fit in the equatorial region.<\/p>\n

The presence of a 2mm protruded equatorial rim<\/strong> allows for a better coverage in the cranial region, enhancing stability.<\/p>\n<\/div>

TRASER\u00ae<\/sup> structure<\/p>\n

The TRASER\u00ae<\/sup> randomized trabecular structure<\/strong> surface in contact with the bone promotes an excellent primary press-fit anchorage and osseointegration [1].<\/p>\n

Inner surface VITAL-B\u00ae<\/sup> coating<\/p>\n

The VITAL-B\u00ae<\/sup> TiNbN coating<\/strong> on the inner surface of the cup guarantees an optimal tribology for the coupling with the joint insert.<\/p>\n<\/div>

Trabecular surface<\/p>\n

The dimension and randomized geometric shape of the trabecular surface, very similar to trabecular bone, offers an ideal structure for bone ingrowth, ensuring the secondary fixation of the implant.<\/p>\n<\/div>

Dual Mobility inserts<\/p>\n

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.<\/p>\n

They are made of UHWMPE (GUR1020) without calcium stearate, available also with Vitamin E VITAL-E\u00ae<\/sup><\/strong> and VITAL-XE\u00ae<\/sup><\/strong> version (cross linked).<\/p>\n<\/div>
