Expersus Hip Stem
Ti6Al4V (ISO 5832-3), cementless
The OHST OEM Expersus Hip Stem is an artificial hip prosthesis for cementless or cemented fixation inside the femur. The cementless version of the Expersus Stem is made of titanium alloy Ti6Al4V (ISO 5832-3) and comes with a 12/14 cone. The stem can be combined with both metal and ceramic femoral heads.
Apart from the polished neck area, the cementless Expersus Hip Stem has an all-round titanium plasma spray and hydroxyapatite coating. The coating accelerates growth of the bone onto the implant, thereby promoting stable and long-term fixation.
In order to treat the various femoral anatomies of the patients, the hip stem also 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. The bio-mechanical parameters: Center of rotation, leg length and CCD angle result in a broad spectrum for the reconstruction of the natural joint geometry.
