Features
• Driving Platform: Threaded slot designed for rotational and axial implant control during stem insertion
• Lateral Shoulder: Rounded lateral shoulder designed to ease stem insertion and minimize risk of fracture
• Plasma Spray: Coating thickness provides 0.5mm (0.25mm per side) additional press-fit for initial stability and long-term
• Proximal Taper: 3°proximal anterior/lateral/posterior taper designed for proximal fill
• Flare: Standard and Reduced flare options designed to ensure metaphyseal fit
• Surface Roughness: Light grit blast texture of titanium stem promotes bone ongrowth and implant stability
• Distal Splines: Designed to provide additional 1mm press-fit (0.5mm perside) for rotational stability
• Sizes: Available in Reduced Flare, Sizes 10-16 and Standard Flare, Sizes 10-18
• Distal Bullet Tip: Round distal tip reduces stress between implant and bone, decreasing potential for thigh pain and risk of fracture during stem insertion
• Distal Slot: Reduces potential for thigh pain and risk of fracture during stem insertion
