Morphometric wedge femoral stem, an evolution of the conventional tapered wedge stem that is SOMA-designed* for today’s diverse THA patient population.
Accolade II’s Morphometric Wedge is designed to address modern demands with 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.1 Accolade II has been shown to allow for enhance stability,2 decreased intraoperative femoral fractures,3 as well as survivorship and functional outcomes4,5 which may lead to satisfied patients.5,6
Clinically, Accolade II has shown to allow for significantly better overall canal fit than conventional tapered wedge design1 with five times less intraoperative fractures observed compared to conventional tapered wedges3 and less than 0.1mm subsidence pursuant to a 2-year RSA study11. Additionally, Accolade II has shown 100% aseptic survivorship pursuant to a 5-year mean follow-up study (n=186).4
Key features include:
Size-specific medial curvature: Offers increasing proximal conformity to enhance primary stability.6,7
Enhanced proximal-distal proportions:7 Shown to mimic canal anatomy to avoid distal-only engagement and achieve cortical fit.8,9
Optimized stem length: Designed to enable muscle-sparing approaches such as Direct Anterior or Direct Superior without sacrificing stability.7,10
