LINK -Model SP II -Hip Prosthesis System
The design is adapted to the anatomical shape of the femur. Successfully used for 40 years1. Proven by a wealth of clinical data.1, 5. Minimal occurrence of periprosthetic fractures11. 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.
Developed in 1978, and 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.
