Description

Accolade II’s Morphometric Wedge is designed to address modern demands with novel technology by evolving conventional tapered wedge femoral stem design with size specific medial curvature to more closely fit a broad range of bone sizes and shapes of today’s patient population. Stryker Orthopaedic Modeling and Analytics, or SOMA, is a system that enables population-based design and has powerful functionality with which to design, model, and analyze novel orthopaedic devices. Stryker utilized SOMA technology to design a novel stem building upon the conventional tapered wedge femoral design, incorporating features to allow for an enhanced implant fit in today’s patient population. By establishing an increased canal fit and fill3, Accolade II has been shown to allow for enhanced stability, decreased intraoperative femoral fractures, as well as survivorship and functional outcomes, which may lead to satisfied patients. An illustrated look at the process by which SOMA technology is employed in implant design is described below. Key benefits Unique size-specific medial curvature Offers increasing proximal conformity to enhance primary stability. Initial stability may be increased by creating a higher conformity between the implant and the femoral cortices, leading to a larger area of contract. Enhanced proximal-distal proportions Distal-only engaged femoral stems can experience stress shielding and consequently may lead to elevated failure rates due to loosening and migration.3 In order to better mimic the femoral anatomy and avoid distal-only engagement, a more anatomic implant growth rate is needed.
