Cemented ACOR®

Hip - Femoral stems Primary

CE2797

Primary Anatomical Femoral Stems.
The ACOR® Modular stem is available in cemented and cementless versions.
Neck modularity allows for accurate, flexible restoration of the joint centre and better control over leg length.
The modular version has been in clinical use since 2006.

Grooves increase the bone–implant contact surface.
Entire stem has highly polished finish to prevent abrasion of the cement mantle.
Proportionately scaled sizes.
Material: titanium.

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.

Line of 4 reversible modular necks that allow the extramedullary portion to be adjusted independently of the intramedullary portion, providing:
- Optimised bone anchorage for all indications, without having to modify the femoral neck cut or impaction level.
- Optimised joint stability and reduced impingement risk.
- Optimised offset.
- Preserved leg length.
- Restored joint centre.

The neck–shaft ankle is determined by the chosen neck:
- 137° (L/M, L/M+10.5, A/R necks).
- 145° (L+/M+ neck in medial position).
- 129 (L+/M+ neck in lateral position).
The combination of 3 head lengths and modular necks results in 24 different joint centre positions.
Material: titanium.

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

The ACOR® instrumentation can be used during conventional surgery or with Computer Assisted Surgery (AMPLIVISION®):
- 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
