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 Klassic® Blade Femoral Stem is a tapered wedge with Ti-Coat®, a rough porous sintered titanium coating for biological fixation. The combination of a smooth medial transition (patent pending) to the Ti-Coat and a relieved distal tip eases insertion for both anterior and posterior approaches. Offered in standard and lateral offset necks, the stem is designed with flexibility and fit in mind.
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™ or E-Link® Poly and offers one insert for every cup to establish a 5mm minimum poly thickness to ensure that the center of rotation stays constant.
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.1 Cross-linked at 8 Mrads, ApeX-LNK is packaged in N2 and provides wear reduction without jeopardizing strength.2
Femoral heads are provided in both Ceramtec BIOLOX®delta Ceramic and Cobalt Chrome.
