HARMONY Acetabular Cup

Trabecular Acetabular System

Product Overview

  • 180° & Deepened Curved Surface Design
    Maximizes bone contact, enhancing press-fit stability, and promoting bone ingrowth.
  • Tight Press-Fit Design
    Ensures effective initial fixation, supporting long-term bone integration.
  • HA+Ti Double Coating (Patented)

Structure:

  1. Surface Layer: 50μm vacuum plasma-sprayed HA coating
  2. Intermediate Layer: Vacuum plasma-sprayed titanium microporous coating Substrate: Ti6Al4V
  3. Combines titanium’s strength with HA’s bioactivity for superior fixation.
  4. Plasma Spraying Process: Ensures fast, durable coating with complete HA dissolution for enhanced osseointegration.

Special Description

Surface screw hole design

DDH: 6 screw holes (for deformity fixation) 

 

Standard: 3 screw holes (fixed to the posterior superior bone  for effective anchoring)  

Minimized Backside Wear

  • Utilizes a triple locking system combining taper connection, concave tooth matching, and an annular anti-retrogression mechanism.
  • High dome support ensures maximum contact between the polyethylene liner and outer cup for effective force transmission, reduced micro-motion, and minimized debris.
  • An ultra-mirror polished inner surface further decreases liner wear.

Ti+HA double coating Porosity: 70%

Ti coating thickness: 325 µm

HA coating thickness: 50 µm

Increase  cup surface roughness to enhance friction and provide immediate stability.

Good biocompatibility, effectively inducing bone growth.

180° and deepened curvature design

180° full coating coverage to increase the surface area for bone growth  

2mm extended cup can reduce soft tissue damage during liner implantation  

Deepened curvature design to ensure sufficient bone coverage
