Revision femoral stem SP II

The design is adapted to the anatomical shape of the femur Successfully used for 40 years Proven by a wealth of clinical data. Minimal occurrence of periprosthetic fractures Minimally invasive implantation Neutralizes torsional forces: The curved shape of the stem enables it to finds its way into the femoral canal, where it adapts perfectly to the anatomy.6 This means that stress peaks, as occur with three-point locking of straight shafts, are avoided and the stem has greater rotational stability. Available with a modular prosthesis head since 1984, this femoral stem was a great success and had a major influence on the principle of the anatomical hip prosthesis.1 The S‑shaped curvature, which follows the natural anatomy of the femur, has proved highly successful in this system. This has been repeatedly confirmed over the last 40 years in numerous publications, including the Swedish Hip Arthroplasty Register.1, 3 The outstanding clinical history was the reason for developing the ribbed prosthesis, the C.F.P. stem, and the SP-CL, based on the same principle. Anatomical design: The anatomical shape of the stem enables it to fit centrally in the medullary canal. This helps to ensure a uniform cement coating, which can envelop the implant optimally.7 At the same time, anteroposterior and mediolateral ribs contribute to rotational stability. Optimal anatomical reconstruction: The SP II offers a system with great modularity. The multiplicity of possible variations in CCD angle, neck length, and stem length gives maximum flexibility for reconstruction of the anatomical structures in primary and revision arthroplasties.
