Primary Anatomical Femoral Stems.
The ACOR® stem is available in monoblock and modular versions.
The monoblock version ACOR® monobloc is available in Standard and Lateralised models.
The modular version includes 4 modular necks.

Grooves increase the bone-implant contact area; they are closed proximally and open distally.
Proportionately scaled sizes.
Impaction limit corresponds to HAP boundary.
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.
Range of 4 reversible modular necks allowing extra-medullary adjustment independently from intra-medullary:
• Improved bone anchoring
• Improved articular stability and lower impingement risk
• Improved offset management
• Leg length preservation
• Articular center reconstruction
The neck-shaft angle varies depending on the chosen neck:
• 137° (L/M, L/M+10.5, A/R necks)
• 145° (L+/M+ neck in medial configuration)
• 129° (L+/M+ neck in lateral configuration)
Paired with 3 neck lengths, modular necks offer up to 24 different articular centers.
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®:
-Anterior approach with patient on their side.
-Anterior approach with patient supine.
-Anterior Hueter approach with patient supine.
