The Signature Aria™ stem is based on European philosophy of a flat tapered wedge. It is manufactured from Ti6Al4V alloy with 50% of the stem circumferentially Titanium plasma coated.
The plasma coating is a macro-roughened surface which improves bone ongrowth. The distal stem is matt finished to reduce painful end loading. The flat rectangular geometry of the Signature Aria stem provides excellent rotational stability. The stem is available with a neck angle of 132 degrees for 13 body sizes in both standard and lateral offsets.
