  • Lateral, Anterior and Posterior Fins: provide for soft tissue attachment

  • Smooth Distal Stem: to minimize stress shielding of the humerus

  • Anatomical Medial Curve: improves fit of the stem to proximal humerus

  • Distal Flutes: increase stem flexibility; allows for medullary revascularization

  • Reduced Collar Size: increases visibility of the stem/bone interface
