Cementless femoral stem SMS®

The optimal reconstruction of the individual anatomy and biomechanics of each patient is a crucial part in THA. The SMS femoral stem has been designed to meet today’s THA challenges in a growing patient population . The stem is designed to achieve a more physiological proximal load transfer and restore the individual anatomy of the patient . The SMS’s stem design has been determined and validated based on the analysis of anthropometric data of hundreds of 3D femoral models collected in the MyBody database . As part of the P-Family Hip System, together with AMIStem-P and QUADRA-P, SMS represents a valuable solution for patients with good bone quality, especially young and active patients with Dorr A and B+ femurs. SMS’s reduced length design and distinctive curvature allow this stem to be the optimal choice for all MIS procedures, such as the AMIS approach. Optimized Metaphyseal Fitting SMS’s optimized design, characterized by an anatomic shape and a distinctive curvature, has been conceived to easily position the implant according to the AMIS technique and potentially reduce the risk of calcar fractures. Thanks to the high fit and fill, the stem adapts its position to the morphology of the proximal femur of the patient by means of a methapyseal press-fit in the intertrochanteric region. MectaGrip coating strengthens the bone-implant interface, resulting in a potentially improved load transfer
