Metal Liner for Dual Mobility Cup

Description

The Metal Liner for Dual Mobility Cup is a high-performance component designed to provide a seamless, low-friction articulating interface within dual mobility hip systems. Serving as the vital bridge between the acetabular shell and the mobile polyethylene bearing, this metal liner is engineered to withstand the rigorous mechanical demands of total hip replacement (THR). By providing an ultra-smooth internal surface, it facilitates the secondary articulation of the dual mobility system, which is critical for maximizing range of motion and preventing dislocation.

Manufactured from premium orthopedic-grade materials such as Cobalt-Chrome (CoCr) or Titanium Alloy, these liners are precision-machined to ensure a perfect fit within the acetabular cup. The high-polish internal finish is designed to work in tandem with mobile bearings, minimizing friction and polyethylene wear. Whether used in complex primary cases or challenging revision surgeries, the metal liner provides the structural rigidity and load-bearing capacity required for long-term implant survivorship and joint stability.

Key Features & Benefits

• Ultra-Smooth Articulating Surface: Features a high-gloss, mirror-polished internal finish that reduces frictional torque and optimizes the movement of the mobile polyethylene insert.

• Superior Material Strength: Crafted from high-strength Cobalt-Chrome or Titanium to provide exceptional resistance to deformation, wear, and corrosion under heavy physiological loads.

• Enhanced Joint Stability: Forms the external boundary of the dual-bearing system, enabling a high “jump distance” that effectively neutralizes the risk of post-operative dislocation.

• Optimal Load Distribution: The rigid metal construction ensures uniform stress distribution across the acetabular interface, protecting the underlying bone and enhancing the longevity of the construct.

• Precision-Machined Fit: Designed with exact tolerances to ensure secure seating within compatible acetabular shells, preventing micromotion and ensuring a stable foundation.

Primary Clinical Applications

• High-Stability Primary THR: Ideal for patients with high-risk factors for instability, such as those with neuromuscular conditions, high BMI, or advanced age.

• Revision Hip Arthroplasty: A critical component for reconstruction in cases where recurrent dislocation or significant bone loss requires a more robust and mobile solution.

• Post-Traumatic Reconstruction: Provides a reliable articulating surface for patients undergoing hip replacement following complex pelvic or femoral neck fractures.
