SPC Hip Stem

The SPC hip stem is a hip endoprosthesis for cementless anchorage in the femur.
The principle is based on the findings of Prof. Lorenzo Spotorno, which has been proven for over 20 years. Made of titanium (ISO 5832-11) and equipped with a 12/14 cone, the stem can be combined with both metal and ceramic femoral heads. For the different femoral anatomies of patients, the SPC hip stem is available in 13 sizes, each with three different CCD angles.

 This results in a broad spectrum for reconstruction of the natural joint geometry based on the biomechanical parameters as center of rotation, leg length and CCD angle. The primary anchorage is based on the press-fit principle. After preparation of the implant bed, the double-conical stem body is pressed metaphysically into the cortico-cancellous bone. The ribs compressing the cancellous bone provide high primary stability, which virtually eliminates any relative movement and at the same time favors secondary anchorage.

Finally, secondary anchorage is achieved by osteointegration, which is favored by used titanium alloy and the surface roughness. All implant variants of the SPC hip stem can be inserted using the same instrumentation and surgical technique. Various test cones with the corresponding angles are available for the modular rasps, which are used for intraoperative trial positioning and thus to confirm the implant size and variant selected pre-operatively.
