The Klassic HD® Hip System evolved from the optimal design features of the most successful tapered stems and acetabular constructs.
Our instrumentation is streamlined to offer surgeons both ease and flexibility of use. Three instrumentation trays offer reduced shipping and sterilization costs, require less storage space, and lower instrumentation costs.
State-of-the-art design and materials offer surgeons a premium implant system, while a streamlined distribution model allows efficiency.
The patented1 Klassic HD Femoral Stem has a double-wedge taper with Ti-Coat porous coating for biological fixation, mid-stem grit blasting, and a smooth polished distal tip. The Klassic Blade Femoral Stem is a single tapered wedge with a relieved distal tip and a smooth medial transition to the Ti-Coat porous coating.
The Klassic HD Acetabular Cup is a thin-walled hemispherical cup with 1.5mm of press-fit at the rim. Ti-Coat porous coating offers 60% porosity for biological fixation.
The Klassic HD Acetabular Insert features ApeX-LNK™ and E-Link® and offers one insert for every cup to establish a minimum poly thickness (5mm) to ensure that the center of rotation stays constant. Our dual purpose insert, available in ApeX-LNK, acts as both trial and implant to reduce the number of surgical steps and to help ensure accuracy (patent pending).
E-Link Poly is a Vitamin E stabilized highly cross-linked ultra high molecular weight polyethylene. Vitamin E is blended into the UHMWPE in powder form, then compression molded, and cross-linked by gamma radiation to 10 Mrads. E-Link utilizes Vitamin E which has been shown to quench free radicals generated from the cross-linking process yielding oxidative stability.2 Cross-linked at 8 Mrads, ApeX-LNK is packaged in N2 and provides wear reduction without jeopardizing strength.3
Femoral heads are provided in BIOLOX®delta Ceramic and Cobalt Chrome. Both are offered in four head lengths and two diameters for primary and revision cases.
