Dual Mobility

Trabecular Acetabular System

Product Overview

Metal Liner

  • Durable and Biocompatible

Made from cobalt-chromium-molybdenum alloy, offering high strength, wear resistance, and excellent biocompatibility.

  • Reduced Wear

Mirror-polished interior surface minimizes wear.

  • Secure Fixation:

The metal-lined stabilizing column design locks firmly with the outer cup taper for enhanced stability.

PE Liner

  • Enhanced Mobility:

Movable design increases joint mobility and lowers dislocation risk.

  • Soft Tissue Protection

The edge bevel design prevents soft tissue impingement.

  • Dislocation Prevention

Closure design enhances femoral head stability, reducing the risk of dislocation.

Special Description

Interface 1: Dual Mobility PE Liner-Femoral Head

Interface 1: Normal range of motion (80%)

Interface 2: Dual Mobility Metal Liner-Dual Mobility PE Liner

Interface 2: Additional Range of Motion (20%)

Flexion / Extension

Abduction / Adduction

Internal / External

ROM can be increased to over 200°, significantly surpassing industry standards.

Compared to traditional prostheses, the dual mobility can increase flexion by 30°, adduction by 15°, and external rotation by 22°.

Excellent Compatibility

The metal liner can match the conventional acetabular cup, realizing the flexible matching of multiple liners in one acetabular cup.

Reduced Risk Of Dislocation

Large diameter liner can effectively enhance the stability of joints and basically achieve "zero" dislocation rate.

Guaranteed Initial Stability

Screw fixation can be selected during the operation to avoid early loosening.

Increased Range of Motion

Dual Mobility structure design, which can provide a maximum range of motion of more than 200 degrees.

Guide Peg Design

Provide better guidance for the installation of the metal liner, ensure that the insertion direction of the metal liner is align with the axis of the acetabular cup, and is convenient for operation.

Ultra Low Wear Rate

Mirror polishing on the inside of metal liner can be compatible with movable polyethylene liner and ceramic head to form a safe and effective low friction interface.
