Shell Features
Integrity of the Shell/Insert Locking Mechanism
- Three screw holes located in one quadrant of the cup allow for surgical flexibility.
- An apical hole plug is optional for sealing the bone/implant interface.
- A titanium shell with irregularly layered porous beads enhances initial fixation and long term bone apposition.
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 UHMW polyethylene liners. This allows the surgeon to select the bearing material most appropriate for a wide range of patient demands and activity.
- 14° flared rim enhances fit for initial and long term stability
- Beaded, porous surface for bone fixation
- Solid, quadrant, and multi-hole options for adjunct fixation when required
- Titanium for biocompatibility
- Apical hole allows visualizing component seating
- 18° internal taper securely locks liners in the shell minimizing potential for micromotion and backside wear
