Cup and Head Combination Options

The Tesera Trabecular Acetabular System includes configurations for head sizes up to 40 mm and cup sizes up to 66 mm. Femoral heads are available in CoCr and BIOLOX® delta ceramic.

Components with the Tesera structure are created using electron beam manufacturing (EBM). The solid and porous regions of the components are built up layer by layer from titanium-alloy powder in one continuous process; thus, the Tesera structure is integral to the component and is not a coating.
