The stellaris cone stem is designed for non-cemented fixation in demanding bone conditions at the proximal end of the femur as for more routine cases.
The implant is made of titanium (TAV) according to ISO 5832-3. Its rough-blasted surface promotes rapid osseo integration. The highly polished neck reduces the risk of soft tissue damage.
The stems are available in a standard (CCD angle 133°) and a lateral (CCD angle 126°) version in 16 sizes each version. The stems up to the size 24 have a length of 117.5 mm and the stellaris Long stems have a length of 142.5 mm.
Philosophy and design
The basic geometry of the standard and lateral version is identical; if looking at the same size. The only difference is the position and length of the neck.
The cone angle of 5° together with the eight longitudinal ribs that are arranged on the circumference of the stem, promote a high degree of rotation stability and excellent primary stability of the prosthesis.
The philosophy and design of the implant allows a wide option of positioning of the anteversion, which is a very important feature for dysplastic hips or special proximal femur situations. The use of the stellaris adapater for anteversion is highly recommended, even in routine cases, to avoid implantation with excessive anteversion.
