The Signature Origin™ cementless hip stem manufactured from Ti6Al4V, is coated on its full length with hydroxyapatite and has a 12/14 taper which is compatible with the range of Signature femoral heads as well as Ceramtec BIOLOX® delta ceramic heads. The low profile lateral shoulder is intended to ease insertion to assist in reduced insertion techniques, including anterior approach.
The stepped stem geometry is intended to convert hoop stresses into compressive loads. Vertical and horizontal grooves are intended for rotational and axial stability. The Origin stem is available in a variety of offsets and neck angles to provide options to match patient anatomy. Collared stems are also available, which are intended to resist subsidence and add rotational stability*.
