Libertas® Cemented Stem
Proven Cemented Fixation. Immediate Stability. Designed for Fracture and Primary Hip Arthroplasty.
The Libertas® Cemented Stem is engineered for predictable fixation in patients where bone quality, anatomy, or clinical scenario favors cemented reconstruction. Featuring a polished, double-tapered design manufactured from high nitrogen stainless steel, the system is built to optimize cement mantle performance and controlled load transfer.
Why Cemented Fixation
Not every femur is suited for uncemented press-fit. In elderly patients, osteoporotic bone, fracture settings, or compromised canal morphology, cemented stems offer immediate stability independent of bone quality.
Clinical drivers for cemented use include:
- Poor metaphyseal bone quality
- Fragility fractures
- Dorr Type C femurs
- Urgent fracture cases requiring immediate fixation
- Patients where biological ingrowth potential is limited
Cemented fixation provides:
- Immediate mechanical stability
- Controlled load transfer through the cement mantle
- Reduced risk of intraoperative fracture in compromised bone
- Proven long-term survivorship in appropriate indications
Clinical Application
The Libertas Cemented Stem is appropriate for:
- Primary total hip arthroplasty in compromised bone
- Femoral neck fracture hemiarthroplasty
- Revision scenarios where cement fixation is preferred
- Patients where immediate stability is critical
Cemented fixation remains a vital tool in modern arthroplasty. It is not a fallback. It is an intentional choice based on patient biology and surgical judgment.
