Minimally invasive femoral stem SP-CL®

The S curvature follows the natural anatomical shape of the femur Rib profile for high primary stability and structural elasticity Bone preserving Minimally invasive implantation LINK HX coating Developed for physiological force transmission Metaphyseal fixation of the SP-CL is assisted by the HX coating (CaP). At the same time, the polished distal stem region protects against thigh pain. Medially the SP-CL rests along the length of the calcar (Shenton’s line) and is intended to promote a physiological distribution of forces. Reduced stress shielding The successful ribbed structure provides initial fixation in the compressed cancellous bone. This makes it possible to achieve a design elasticity in spite of the proven “fit and fill” principle in the proximal femur. Thus the ribs not only provide high primary stability,but in combination with the LINK Tilastan- S alloy, they also achieve double elasticity. This can lead to a reduction in “stress shielding”. Bone preserving Anatomically shaped stems necessitate anatomically shaped instruments. The compressors in the SP-CL System follow exactly the anatomical design of the stems and prepare the bone bed for the SP-CL stem according to the natural contours of the intramedullary canal in the proximal femur. While the flat, lateral implant profile is designed to protect the greater trochanter during implantation, cancellous bone compressors help to preserve valuable bone substance during resection. The compact, ergonomically designed instrument set permits effective, smooth intraoperative working.
