Abstract
A fixation device is disclosed for the fixation of proximal humerus fractures includes an implantable humerus plate having a proximal portion adapted to be positioned at a head and medial calcar of the humerus, a distal portion adapted to be positioned along a shaft of the humerus, and a plurality of calcar openings provided through the proximal portion adapted to receive calcar fasteners that extend into the medial calcar. The calcar fasteners are grouped into a rafted configuration and the tips of each fastener are positioned into the calcar region so that torsional forces bearing upon the calcar regions are distributed into the rafted fastener support, thereby avoiding varus collapse of the humerus head after fixation of the fracture.
