Material:
• A polyethene acetabular cup made of UHMWPE
Size:
• Diameter 42 to 60 that fits with Head 28
Design of Cemented Acetabular Cup
Overview: The cemented acetabular cup is engineered to optimize stability, enhance joint motion, and minimize complications in total hip arthroplasty.
Key Design Features
Circle Grooves:
Increased Contact Area: The circular grooves enhance the interface with bone cement, promoting better adhesion and stability.
Internal Rim Design:
Expanded Motion Range: The internal rim is strategically cut to allow greater joint motion while reducing the risk of collision with the femoral stem.
Metal Ring Along the Rim:
Radiolucent Line: The metal ring creates a radiolucent line on imaging, aiding in precise positioning and alignment during surgery.
Anti-Dislocation Design:
Secure Liner Placement: The anti-dislocation liner can be rotated into the optimal position, reducing the risk of dislocation and subsequent complications.
Biconical Surface Design:
Enhanced Fit: Both the shell and liner feature a biconical surface that ensures a tight fit, preventing slippage and reducing polyethylene wear debris.
