Metal augments are made of tantalum, a bio-inert and corrosion-resistant metal that can be shaped into a highly porous “metal foam” with a high coefficient of friction and low stiffness
With increasing Paprosky grades, including discontinuity, a cup/cage construct may be the only available option for acetabular reconstruction
