Product Details
HARMONY Acetabular System: Leading China Suppliers & Factory Offering Advanced HA+Ti Coating for Optimal Bone Integration
Surface Screw Hole Design
-
DDH: 6 screw holes (engineered for deformity fixation)
-
Standard: 3 screw holes (fixed to the posterior superior bone for highly 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.

Frequently Asked Questions
What options are available for the surface screw hole design?
The system offers two distinct configurations: a DDH version featuring 6 screw holes optimized for deformity fixation, and a Standard version with 3 screw holes designed to fix to the posterior superior bone for highly effective anchoring.
How does the system minimize backside wear?
Backside wear is minimized through a combination of a triple locking mechanism (taper connection, concave tooth matching, and an annular anti-retrogression system), high dome support for optimized force transmission, and an ultra-mirror polished inner cup surface that reduces micro-motion and debris.
What are the specifications of the Ti+HA double coating?
The Ti+HA double coating features a porosity of 70%. The Titanium (Ti) coating has a thickness of 325 µm, while the Hydroxyapatite (HA) coating has a thickness of 50 µm.
What clinical benefits does the double coating provide?
The double coating increases the cup's surface roughness, enhancing initial friction for immediate stability, while offering excellent biocompatibility to effectively induce long-term bone growth.
How does the 180° and deepened curvature design improve performance?
The 180° full coating coverage maximizes the surface area for bone integration. The deepened curvature ensures sufficient bone coverage, and the 2mm extended cup helps reduce soft tissue damage during liner implantation.
