SEE Trabecular Acetabular Cup -Revision
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
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
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
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
SEE Trabecular Acetabular Cup Revision JCT
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 are the benefits of 3D EBM printing technology in the SEE Trabecular Acetabular System?
The 3D EBM (Electron Beam Melting) printing technology provides excellent biocompatibility and ensures there is no risk of surface delamination, which effectively promotes long-term bone growth.
How does the "Starry Sky" screw hole design assist in revision surgery?
Featuring 6 dome holes and 9 peripheral holes (all using Φ 6.0 screws), the "Starry Sky" design provides maximum surgical flexibility. It allows surgeons to choose optimal screw placement, making it highly suitable for patients with irregular acetabular shapes and severe bone defects.
Why is the 75%-80% porosity and 600-800 µm pore size significant?
This specific configuration maximizes contact with the host bone, facilitates cell and blood flow to enhance bone formation, and reduces the elastic modulus of the implant to minimize stress shielding.
What is the advantage of using a cup with an HXLPE cemented liner?
The Highly Crosslinked Polyethylene (HXLPE) cemented liner can be adjusted within a defined "safe zone" to fine-tune anteversion and abduction angles, reducing the risk of postoperative dislocation while offering superior wear and oxidation resistance.
What function does the threaded Hole Cover serve?
The threaded hole cover seals areas where acetabular screws are not used. This increases the overall contact area and strength of the acetabular cup while preventing bone cement leakage during installation.
