3D SEE Trabecular Acetabular System

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

Uniform joint surface morphology

Ensure that all liner models have the same rotational center position.
