Quatroloc® Femoral System Primary System Fracture System Revision System

	View Features Circumferential porous coating seals the interface Proximal porous coating bears load proximally Lateral flare achieves axial loading in lateral cortex Tapered distal stem with steps achieves distal scratch fit in tapered femur Varying distal sizes Neck preservation improves torsional and axial fixation Augmented offset minimizes abductor load Patented leading edges achieve scratch fit in tapered diaphyseal bone Smooth distal surfaces avoid distal load-bearing Patented parallel ridges avoid wedging Medial steps engage bone and avoid excessive wedging and improve proximal axial loading Parallel sides allow tight fit in "stove pipe" femur Rectangular shape achieves excellent torsional fixation and preserves medullary blood supply
