Alteon® Monobloc Revision Femoral Stem
It incorporates specific philosophies designed to improve surgical experiences and clinical outcomes. The Monobloc Revision Femoral Stem intends to achieve axial and rotational mechanical stability and operative predictability through a carefully engineered combination of design features.
Taper Angle and Spline Design
The 3.5 degree taper angle and flat/broad spline geometry play an integral part in the mechanical stability that is designed to resist axial subsidence and rotation.1

Axial Stability of Different Taper Angles
x-axis: Spine Angle (Deg) / y-axis: Axial Resistance (N/mm)
Reamer and Trial-to-Implant Relationship Predictability
The surgical technique and instrumentation are designed to create a predictable relationship between the reamer, trial and implant locations. The result is a system with the potential for immediate and long-term center of rotation reliability and stability.
