Important element
Product range

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


Elliptical, symmetric cavity allows the modular neck to be reversed.
Morse taper connection.
Threaded hole at bottom of cavity for extraction tool.
Impaction point at top of stem is offset to ensure impaction is in line with shaft axis.
Stem–neck combination: titanium–titanium.

Femoral stem product available in several versions:
- Cemented or Cementless
- Standard or Lateralised (cementless only)


ACOR® instrumentation can be used during conventional surgery or with Computer Assisted Surgery (AMPLVISION®):
- Computer Assisted Surgery of the cup and femoral stem helps to maintain leg length and offset
Several rasp handles suitable for the various hip approaches are available for use with or without AMPLIVISION®:

Posterior approach
Anterior approach with patient on their side
Anterior approach with patient supine
Anterior Hueter approach with patient supine
