Special Description
This section details the advanced structural features of the Trabecular Acetabular Cup system, highlighting initial stability, biological integration, and technology specifications.
Trabecular Acetabular Cup DDH & Standard
Screw hole
Exceptional initial stability:
DDH: 6 screw holes (for deformity fixation)
Standard: 3 screw holes (fixed to the posterior superior bone for effective anchoring)
Revision: "Starry Sky" screw hole—6 dome holes & 9 peripheral holes (all Φ 6.0 screw)
Triple locking mechanism
Maximize liner-to-cup contact to achieve effective force transmission, minimize micromotion, and reduce debris.
3D EBM printing technology
Excellent biocompatibility; No risk of surface delamination, promoting long-term bone growth.
1.08 friction coefficient on trabecular surface
High surface roughness, increasing friction with host bone for superior initial stability.
Tight press-fit design(1.5mm, single-size rasp)
Exceptional initial stability.
75%-80% High porosity
Achieves reliable bone growth:
- Increases contact with the host bone
- Facilitates cell and blood flow, promoting bone formation
- Reduces elastic modulus, minimizing stress shielding
3D interconnected porous structure
Ensuring reliable bone growth.
600-800 µm pore size
In vivo tests show: 800 μm pore size promotes bone growth.

"Starry Sky" screw hole
6 dome holes & 9 peripheral holes (all Φ 6.0 screw)
Providing flexibility during surgery and allowing the surgeon to choose the optimal screw placement.
More suitable for patients with severe acetabular bone defects and irregular acetabular.
Load direction aligns more closely with the body's natural lower limb biomechanics, providing better initial and long-term stability.
Streamlined cup thickness
Preserves more bone while ensuring outer diameter and strength.
Allows for larger femoral heads, improving range of motion, lower dislocation rates, and enhancing stability.
Sizes 48#—74# comprehensively cover all needs for acetabular revision and complex primary replacements.
Acetabular cup with HXLPE cemented liner
The acetabular cup can be adjusted based on the specific condition of the acetabulum. Afterward, the cemented liner can be adjusted within a defined "safe zone" to fine-tune anteversion and abduction angles, making revision surgery more flexible and straightforward, while preventing postoperative dislocation.
The highly crosslinked material offers excellent wear resistance and anti-oxidation properties.
Hole Cover (threaded)
Sealing in areas where acetabular screws are not implanted.
Increase acetabular contact area.
Increase overall strength of the acetabular cup.
Prevent leakage of bone cement.

"Starry Sky" screw hole design
The design features 6 evenly distributed peripheral screw holes and 6 dome screw holes, providing flexibility during surgery and allowing the surgeon to more effectively choose screw placement.
More suitable for patients with severe acetabular bone defects and irregular acetabular shapes.
3D SEE Trabecular Acetabular System
Uniform joint surface morphology
Ensure that all liner models have the same rotational center position.

Frequently Asked Questions (FAQ)
What is the difference between the DDH and Standard cup screw holes?
The DDH cup features 6 screw holes specifically designed for deformity fixation. The Standard cup features 3 screw holes designed to fix to the posterior superior bone for effective anchoring.
How does the 3D EBM printing technology benefit bone growth?
3D EBM printing technology provides excellent biocompatibility and eliminates the risk of surface delamination, which effectively promotes long-term bone growth.
What are the advantages of the 75%-80% high porosity and 3D interconnected structure?
This structure achieves reliable bone growth by increasing contact with the host bone, facilitating cell and blood flow to promote bone formation, and reducing the elastic modulus to minimize stress shielding.
What is the "Starry Sky" screw hole design?
The "Starry Sky" design features 6 dome holes and 9 peripheral holes (all using Φ 6.0 screws) for Revision cups, and 6 peripheral plus 6 dome holes for Revision JCT cups. This configuration provides maximum surgical flexibility for optimal screw placement.
How does the HXLPE cemented liner improve revision surgery?
It allows the cemented liner to be adjusted within a defined "safe zone" to fine-tune anteversion and abduction angles after the cup is adjusted, offering surgical flexibility and preventing postoperative dislocation.
What is the function of the threaded Hole Cover?
The threaded Hole Cover seals areas where acetabular screws are not implanted, increases the acetabular contact area, enhances the overall strength of the cup, and prevents the leakage of bone cement.
