Cemented femoral stem ACOR®

Neck modularity allows for accurate, flexible restoration of the joint centre and better control over leg length. Grooves increase the bone–implant contact surface. 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 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.
