Expersus Hip Stem
CoCrMo (ISO 5832-12), cemented
The OHST OEM Expersus Hip Stem is an artificial hip prosthesis for cementless or cemented fixation inside the femur.
The cemented version of the Expersus Stem is made of CoCrMo wrought alloy (ISO 5832-12) and comes with a 12/14 cone. It has a smooth, fully polished surface and can be combined with both metal and ceramic femoral heads.
In order to treat the various femoral anatomies of the patients, the hip stem comes in 9 sizes with a standard 125° and standard 135° variant. The body of the stem has a triple tapered shape in order to ensure both self-clamping as well as the necessary rotational stability. Thus there is a wide range of possibilities for the reconstruction of the natural geometry of the joint taking into account the bio-mechanical parameters center of rotation, leg length and CCD angle.
