Implacross PE insert 0º - Non-constrained polyethylene acetabular liner

Intended purpose

A polyethylene cup insert component used with a cementless acetabular cup as part of the primary operation of the hip joint impaired by conditions such as arthrosis, rheumatoid arthritis, femoral neck fractures, avascular necrosis, or hip dysplasia.

Functional description

Crosslinked UHMWPE insert for use with Ecofit cups. The liners are coupled to the metal shell by two mechanisms: 1) a taper fit between the liner and the metal shell provided by a conical taper shape of the exterior surface of the liner that matches the conical taper geometry and inner diameter size of the interior of the metal shell and 2) a snap fit mechanism of four lugs on the inferior aspect of the PE liner that snap into a circumferential groove at the bottom of the metal shell.
