"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 are the screw hole options for the Trabecular Acetabular Cup?
The screw hole configurations depend on the model. The DDH cup features 6 screw holes for deformity fixation; the Standard cup has 3 screw holes fixed to the posterior superior bone for effective anchoring; and the Revision cup offers a "Starry Sky" design with 6 dome holes and 9 peripheral holes utilizing Φ 6.0 screws.
How does 3D EBM printing technology benefit patients?
3D EBM printing technology provides excellent biocompatibility and eliminates the risk of surface delamination, which effectively promotes long-term bone growth into the implant.
What is the porosity and pore size of the trabecular surface?
The system features a 75%-80% high porosity with a 3D interconnected porous structure and a 600-800 µm pore size. In vivo testing shows that an 800 μm pore size is highly effective in promoting bone growth.
Why is the "Starry Sky" screw hole design preferred for revision surgeries?
It offers maximum surgical flexibility with 6 dome holes and 9 peripheral holes, allowing optimal screw placement. This makes it highly suitable for patients with irregular acetabular shapes and severe bone defects.
What is the purpose of the threaded Hole Cover?
The threaded Hole Cover seals areas where acetabular screws are not implanted, increases the overall contact area and strength of the acetabular cup, and prevents the leakage of bone cement.
How does the HXLPE cemented liner improve surgery outcomes?
It allows the cemented liner to be adjusted within a defined "safe zone" to fine-tune anteversion and abduction angles. This provides surgical flexibility, helps prevent postoperative dislocation, and offers superior wear and oxidation resistance.
