-
"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, and 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.

Frequently Asked Questions (FAQ)
What is the advantage of 3D EBM printing technology in these acetabular cups?
3D EBM (Electron Beam Melting) printing technology provides excellent biocompatibility and eliminates the risk of surface delamination. This structure actively promotes long-term bone growth into the implant.
How does the "Starry Sky" screw hole design assist in revision surgeries?
The "Starry Sky" design features 6 dome holes and 9 peripheral holes (all using Φ 6.0 screws). This gives surgeons exceptional flexibility in choosing the optimal screw placement, making it highly suitable for patients with severe bone defects and irregular acetabular shapes.
Why is the 75%-80% porosity rate significant for bone growth?
High porosity increases the direct contact area with host bone, facilitates cell and blood flow to promote bone formation, and reduces the elastic modulus to minimize stress shielding.
What is the function of the threaded Hole Cover?
The threaded Hole Cover is designed to seal areas where acetabular screws are not implanted. This increases the contact area of the acetabulum, enhances the overall strength of the cup, and prevents the leakage of bone cement.
How does the streamlined cup thickness benefit range of motion?
The streamlined cup thickness preserves more of the patient's natural bone while maintaining structural strength. This design allows for the use of larger femoral heads, which improves range of motion, enhances joint stability, and lowers postoperative dislocation rates.
