Product Details
China Suppliers Factory - AOS Mesh & Cage System for Acetabular Defect Management in Hip Arthroplasty
Special Description
Posterosuperior Bone Cement Flange
The posterosuperior bone cement flange minimizes unsupported bone cement.
Triple-Flange Reinforcement
3 flanges enhance fixation and offer multiple screw options.
Optimized Flange Thickness
Flange thickness of 3mm, balances structural strength and anatomical compatibility.
Grooved Acetabular Rim Design
The grooved design on the outer rim of the acetabulum improves adhesion to the acetabular rim, enhancing postoperative outcomes. Boosts prosthesis-bone interface stability.
Anatomically Left-Right Differentiation
The left-right differentiation aligns with anatomical characteristics. Ensures better patient-specific fit.
Versatile Screw Hole Design
Well-designed screw holes meet diverse clinical needs. Supports flexible surgical strategies.
Roughened Surface Texture
The rough surface ensures excellent adhesion of bone cement and promotes osseointegration. Enhances long-term bone-implant integration.
The Acetabular Mesh is designed to reinforce defects in the medial acetabular wall, preventing bone graft migration. The mesh can be shaped, bent, and trimmed during surgery to accommodate individual patient anatomy.
Strategically placed slots facilitate precise adjustments. Available in multiple sizes, the Acetabular Mesh provides a customizable solution for acetabular reconstruction.

Frequently Asked Questions
What is the main clinical purpose of the AOS Cage?
The AOS Cage is designed for revision hip arthroplasty to manage bone loss and reconstruct the acetabulum, providing stable fixation and structural support for cemented acetabular cups.
How does the posterosuperior bone cement flange improve prosthesis stability?
The posterosuperior bone cement flange minimizes unsupported bone cement, ensuring a more uniform cement mantle distribution and preventing structural migration or loosening.
Can the Acetabular Mesh be customized during surgery?
Yes, the Acetabular Mesh is designed to be shaped, bent, and trimmed intraoperatively to adapt to the individual anatomical requirements of each patient's medial acetabular wall.
What are the available sizes for the AOS Cage and Rings?
AOS Rings are available in sizes 52 to 62 (Left and Right). AOS Cages are available in sizes 50 to 62 (Left and Right), accommodating various cemented cup sizes depending on cement thickness.
Why is the surface texture of the AOS Cage roughened?
The roughened surface texture is engineered to optimize the adhesion of bone cement to the implant, while simultaneously promoting osseointegration for long-term implant stability.
