Cemented Cup

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

1. Circle Grooves:
   • Increased Contact Area: The circular grooves enhance the interface with bone cement, promoting better adhesion and stability.
2. 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.
3. Metal Ring Along the Rim:
   • Radiolucent Line: The metal ring creates a radiolucent line on imaging, aiding in precise positioning and alignment during surgery.
4. 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.
5. 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.
