Cemented Cup

Material
• A polyethene acetabular cup made of UHMWPE
Design
• Circle grooves increase contact with bone cement
• Internal rim is cut to expand joint motion range and decrease collision
with the stem
• Metal ring along the rim will produce radiolucent line and helps locate
precisely
• Anti-deslocation design
• The anti-dislocation liner can be implanted into the best position by
rotation, that leads to fewer complications after operation. Both shell and
liner adapt a biconical surface design to match tight
• This design could prevent relatively slip which bring polyethelene debris
Size
• Diameter 42 to 60 that fits with Head 28
