Acetabular Cup Liner (10° & 0°)

Description

The Acetabular Cup Liner is the primary articulating interface in a total hip replacement (THR) system, engineered to provide a smooth, low-friction surface for the femoral head. Positioned securely within the acetabular shell, the liner is responsible for absorbing physiological loads and facilitating fluid joint motion. Its design is critical to the longevity of the implant, as the material choice and surface finishing directly impact wear rates and the risk of long-term osteolysis.

Our liners are available in a variety of advanced materials and configurations to suit different patient activity levels and surgical requirements. Each liner features a precision-engineered locking mechanism designed to ensure a rigid, “no-play” fit within the acetabular cup, effectively eliminating micromotion and preventing back-side wear.

Material Options & Specifications

• Highly Cross-Linked Polyethylene (XLPE): The modern standard for durability. XLPE undergoes a specialized radiation and annealing process to significantly reduce wear debris while maintaining excellent fatigue strength. Ideal for a broad range of primary THR patients.

• Ceramic-on-Ceramic / Ceramic-on-Poly: Offering the lowest wear rates available in orthopedics, ceramic liners provide an ultra-hard, scratch-resistant surface. These are particularly suited for younger, highly active patients where maximum implant lifespan is the priority.

• Metal Liners: Engineered for specialized constructs, including dual-mobility systems, providing high mechanical strength and stability in complex reconstruction scenarios.

Key Features & Benefits

• Superior Wear Resistance: Advanced material processing minimizes the production of wear particles, protecting the surrounding bone from inflammatory responses and loosening.

• Secure Locking Interface: Precision-machined rims and tabs ensure a definitive mechanical lock into the acetabular shell, providing a stable foundation for articulation.

• Anatomical Geometry: Available in neutral, hooded, and offset configurations to help surgeons optimize joint stability, restore leg length, and prevent post-operative dislocation.

• Optimized Head-to-Liner Ratio: Designed to accommodate various femoral head diameters (28mm, 32mm, 36mm+), allowing for a greater range of motion and increased jump distance.

• Medical Grade Biocompatibility: All materials are rigorously tested to ensure long-term stability and compatibility within the human body.

Primary Clinical Applications

• Primary Total Hip Arthroplasty (THA): Provides a reliable, low-friction articulating surface for routine hip replacements.

• Revision Hip Surgery: Offers versatile sizing and material options to restore joint function when existing components fail or wear out.

• Complex Hip Reconstruction: Hooded or offset variants are essential for managing patients with high instability or deficient acetabular coverage.
