Product Details
AOS Mesh & Cage System for Acetabular Defects - Trusted China Suppliers & Factory for Hip Revision Solutions
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.
Medial Wall Reinforcement
The Acetabular Mesh is designed to reinforce defects in the medial acetabular wall, preventing bone graft migration.
Intraoperative Customization
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 primary clinical purpose of the AOS Cage?
The AOS Cage is designed for revision hip arthroplasty to manage and reconstruct severe acetabular defects. It features a posterosuperior bone cement flange to minimize unsupported cement and a triple-flange system to enhance implant fixation stability.
How does the Acetabular Mesh prevent bone graft migration?
The Acetabular Mesh acts as a structural barrier to reinforce defects in the medial acetabular wall. By securing the medial wall boundary, it effectively prevents the migration of bone grafts placed during hip joint reconstruction.
Can the Acetabular Mesh be customized during surgery?
Yes, the Acetabular Mesh is designed for intraoperative flexibility. Surgeons can shape, bend, and trim the mesh to match each patient's specific anatomical requirements, aided by strategically placed slots that facilitate easy adjustment.
What are the benefits of the grooved acetabular rim design?
The grooved design on the outer rim of the acetabulum enhances the adhesion between the implant interface and the acetabular rim. This design feature boosts overall prosthesis-bone interface stability and improves long-term postoperative outcomes.
Why is there left-right anatomical differentiation for these implants?
Left-right differentiation ensures that the implant contour aligns accurately with the asymmetrical anatomical structures of the human pelvis. This provides a more precise, patient-specific fit, reducing surgical time and implant mismatch risks.
