Cemented Cup

The cemented cup is an acetabular component used in total hip replacements. Its main features include:

Fixation Type: Cemented, allowing for rapid postoperative mobilization.

Design: Often hemispherical to maximize bone preservation and ensure uniform distribution.

Materials: Typically made of ultra-high-density polyethylene (UHMWPE) for the main component, offering low abrasion. A radiopaque marking ring, often made of stainless steel, is included for surgical positioning and postoperative checks.

Stability and Mobility: Can be designed for dual mobility to reduce the risk of dislocation, with movement between the femoral head and liner, and between the liner and cup. Grooves on the external surface can increase grip and limit micro-movements.

Indications: Used in primary arthroplasty in patients at high risk of dislocation or in revision arthroplasty in cases of repeated dislocations. The choice between cemented and uncemented implants depends on factors such as patient age and bone quality.
