The LINEAGE® Acetabular Cup System has integrated several design features to allow alumina ceramic, cobalt chrome, polyethylene, and cross-linked poly bearings with or without screw fixation. The LINEAGE® Acetabular System provides unsurpassed surgical flexibility for shell fixation and bearing material choices. The LINEAGE® Acetabular Shells are manufactured from Titanium, the material of choice for biocompatibility and reduced stiffness. The unique internal shape and design allow the use of ceramic, metal, or cross-linked liners. This allows the surgeon to select the bearing material most appropriate for a wide range of patient demands and activity.
