Product Details
AOS Mesh & Cage System for Acetabular Defects - Leading China Suppliers and Factory for Surgical 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.
Flexible Reconstruction Solution
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.
