The X-acta Short is a cemented double-tapered stem manufactured in high-nitrogen stainless steel and provided with a PMMA distal centralizer to facilitate stem positioning and uniform cement mantle distribution. It is characterized by a wide range of options, including five sizes and four offsets, which allow the surgeons to accomodate most patient anatomies. This shortened design facilitates the stem implantation through the AMIS approach and preserves the bone stock. The short stem is within an initial limited market release phase.
X-acta stem belongs to Medacta’s cemented stem portfolio, which also includes AMIStem-C, Quadra-C and AMIS-K.
