Cementless femoral stem ACOR®

rightleft

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. Material: titanium. Coating: Uniform 80 µm thick HAP. Anatomic 8° metaphyseal curvature matches the proximal femur's natural curvature. 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
