Product Details
HARMONY Acetabular System: Top China Suppliers & Factory for Advanced Orthopedic Solutions
Surface Screw Hole Design
- DDH: 6 screw holes (engineered 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
- Increases cup surface roughness to enhance friction and provide immediate stability.
- Good biocompatibility, effectively inducing bone growth.
180° & 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 options are available for the surface screw hole design?
The HARMONY Acetabular System offers two configurations: a DDH design with 6 screw holes optimized for deformity fixation, and a Standard design with 3 screw holes designed to fix to the posterior superior bone for effective anchoring.
How does the system minimize backside wear?
It utilizes a triple locking system (taper connection, concave tooth matching, and an annular anti-retrogression mechanism), high dome support for optimized force transmission and reduced micro-motion, and an ultra-mirror polished inner surface to decrease liner wear.
What are the specifications of the Ti+HA double coating?
The double coating features a porosity of 70%, with a Titanium (Ti) coating thickness of 325 µm and a Hydroxyapatite (HA) coating thickness of 50 µm to enhance biological integration.
How does the Ti+HA double coating improve implant stability?
It increases the cup's surface roughness to enhance friction for immediate primary stability while providing excellent biocompatibility to effectively induce long-term bone growth.
What are the advantages of the 180° and deepened curvature design?
This design provides 180° full coating coverage to maximize the surface area for bone growth, features a 2mm extended cup to reduce soft tissue damage during liner implantation, and utilizes a deepened curvature to ensure sufficient bone coverage.
