HARMONY Acetabular System: Leading China Suppliers & Factory for HA+Ti Coated Implants with Enhanced Stability
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 Technology
Porosity
70%
Ti Coating Thickness
325 µm
HA Coating Thickness
50 µm
- Increases 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.
Frequently Asked Questions
What screw hole configurations are available in the HARMONY Acetabular System?
The system offers two options: a DDH design featuring 6 screw holes for deformity fixation, and a Standard design with 3 screw holes fixed to the posterior superior bone for effective anchoring.
How does the system minimize backside wear?
It combines a triple locking system (taper connection, concave tooth matching, annular anti-retrogression mechanism), high dome support for maximum liner-cup contact, and an ultra-mirror polished inner surface to decrease micro-motion and debris.
What are the specifications of the Ti+HA double coating?
The double coating features 70% porosity, a Titanium (Ti) coating thickness of 325 µm, and a Hydroxyapatite (HA) coating thickness of 50 µm, promoting immediate frictional stability and long-term bone ingrowth.
What is the advantage of the 180° full coating coverage?
The 180° full coating coverage maximizes the total contact surface area available for osteointegration and bone ingrowth.
How does the 2mm extended cup protect surrounding tissue?
The 2mm extended cup provides protective clearance that helps reduce potential soft tissue damage during the implantation of the liner.
Why is the deepened curvature design used?
The deepened curvature design is engineered to ensure adequate and comprehensive bone coverage for optimal implant positioning and stability.
