Libertas® Cemented Stem

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.

Design Features
