AK-MR Stem provides the opportunity to treat wide variances in patient anatomy, and allowing extensive fixation in the femur, this design philosophy in femoral revision surgery has been impressive. These results show the favorable remodeling of proximal femoral bone stock when excessive bone loss was present;
AK-MR Stem were designed to achieve secure distal fixation in the femur using a sharply splined and tapered distal stem;
The tapered distal stem is designed to wedge into the femoral medullary canal, transferring axial and bending forces, while the splines are press-fit into the bone to provide rotational stability;
A bevel at the distal end of the stem is a design feature intended to increase the ease of insertion, to better accommodate the bow of the femur, and decrease the potential for distal femoral cortical
Multiple sizes in each body type allow for metaphyseal filling, proximal fixation, and proximal support of the prosthesis.
