Expersus Hip Stem
Ti6Al4V (ISO 5832-3), cementless
The OHST Expersus stem is a hip stem prosthesis for cementless or cemented anchoring in the femur.
In the cementless version, the Expersus stem is made of a titanium Ti6Al4V (ISO 5832-3) and is equipped with a
12/14 cone. The stem can be combined with both metal and ceramic femoral heads.
The cementless Expersus hip stem is fully coated with a titanium plasma spray and hydroxyl apatite coating except for the polished neck area. The coating accelerates the attachment of the bone to the implant and thus supports stable
There are also 9 sizes available for different patient femoral anatomies with a standard -125° and standard -135° design. The stem body is double tapered to provide both self-clamping and the necessary rotational stability.
For both the cemented and cementless versions, this results in a wide range for reconstructing the natural joint geometry based on the biomechanical parameters of center of rotation, leg length and CCD angle.
