OHSTO medical technology For a cementless anchoring in the femur The principle of the SPC hip stem is based on the findings of Prof. Lorenzo Spotorno. The product has been tried and tested for more than 20 years. Made of a titanium wrought alloy (ISO 5832-11) and fitted with a 12/14 cone, the stem can be combined with both metal and ceramic femoral heads. For the various femoral anatomies of the patients the SPC hip stem is available in 13 sizes, each with three different CCD angles. There is therefore a wide range available for the reconstruction of the natural geometry of the joint using the biochemical parameters of center of rotation, leg length and CCD angle. The primary anchorage is carried out in accordance with the press-fit principle. After preparation of the implant bed, the double conical-shaped body of the stem is pressed metaphysically into the cortico-spongious bone. A high degree of primary stability is achieved by the spongiosa-com-pressing ribs, so that almost all relative movement is excluded and the secondary anchorage improved at the same time. The secondary anchorage is finally achieved by osteointegration, which is promoted by the osteophilic titanium alloy and the roughness of the surface.

PRODUCT DESCRIPTION Ti6Al7Nb (ISO 5832-11) rough surface, blasted Metal and ceramic femoral heads All implant versions of the SPC hip stem can be incorporated with the same set of instruments and the same operating techniques. For the modular rasps there are various test cones available with the corresponding angles which serve the purpose of intraoperative trial repositioning and are therefore used for confirming the pre-operatively selected implant size and version. All instruments are equipped with an ergonomically formed silicone grip system which meets all cleaning and sterilization requirements....
