The Expersus stem is a hip stem prosthesis that allows either the cemented or the cementless version of the stem to be inserted with one instrumentation.

In the cemented version, the Expersus stem is made of implant steel (5832-9) and in the cementless version, the Expersus stem is made of a titanium Ti6Al4V (ISO 5832-3). The stem is equipped with a 12/14 taper and can be combined with both metal and ceramic femoral heads.

The cemented Expersus hip stem has a smooth satin finish, while the neck area is completely polished. In the cementless version the stem is fully coated with a titanium plasma spray and hydroxyl apatite except for the polished neck area.

For the different femoral anatomies of the patients, up to 10 sizes are available in CCD angles 125° and 135°.

For both the cemented and cementless versions, this results in a broad spectrum for reconstructing the natural joint geometry based on the biomechanical parameters of centre of rotation, leg length and CCD angle.
