The Libertas Mini TR Stem is a tapered, uncemented femoral stem engineered to deliver predictable initial stability with a reduced stem length and distal reduction geometry. It is designed to support efficient femoral preparation and insertion across surgical approaches, including the direct anterior approach.
Shorter length. Confident fixation. Modern workflow.
Libertas® Mini TR Stem
Short Stem. Stable Fixation. Designed for Today’s Hip Reconstruction.
Overview Documents
Designed for Modern Hip Reconstruction
The Libertas Mini TR Stem is built for surgeons seeking:
- Proximal stability without distal over-constraint
- A shorter stem solution for approach-driven cases
- Reliable initial fixation with biologic ongrowth potential
- A streamlined, intuitive instrumentation workflow
Why Mini TR
In primary total hip arthroplasty, proximal–distal mismatch can challenge fit and stability. The Mini TR stem addresses this with distal reduction geometry that supports proximal engagement without forcing distal potting.
Its shortened design can improve access and control during femoral work, particularly in approach-driven workflows such as direct anterior.
Design Highlights
The Mini TR Stem incorporates purpose-driven design elements that work together.
- Reduced stem length — approximately 37 mm shorter than the standard Libertas TR stem
- Distal reduction geometry — designed to accommodate anatomical variation and reduce distal canal over-engagement
- Vertical stabilizing grooves — enhance rotational and axial stability during insertion
- Highly polished tapered neck — designed to reduce impingement potential
- Ti-GrowthC® plasma spray coating — engineered to promote durable bone ongrowth
