Grooves increase the bone-implant contact area; they are closed proximally and open distally.
Proportionately scaled sizes.
Impaction limit corresponds to HAP boundary.
Material: Titanium.
Coating: Uniform 80 µm thick HAP.

Anatomic 8° metaphyseal curvature matches the proximal femur's natural curvature.
Primary stability ensured by ovoid metaphyseal cross-section that optimises metaphyseal filling.
Its length and diameter make it easy to implant through the anterior approach.
Thin, cylindrical distal end contributes to metaphyseal anchoring and ensures diaphyseal guiding.

Oval impaction hole on top of stem.
Threaded hole used for extraction.

Thin femoral neck with small taper (10/12, 5°42‘30’’).
Standard version: Neck-shaft angle 137°.
Lateralised version: Neck-shaft angle 129°.
The joint centre of the Standard stem corresponds to a modular ACOR® stem with A/R neck and regular anteversion/retroversion values.
The joint centre of the Lateralised stem corresponds to a modular ACOR® stem with L+/M+ neck in the lateral position.

Femoral stem product available in several versions:
- Modular.
- Cemented or Cementless.
- Monoblock.
