Claim 0:
1. A stabilization system configured to stabilize a humerus, the system comprising:
a bone plate, the bone plate comprising an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion along a second axis, the bone plate comprising first and second polyaxial openings, a plurality of fixed angle openings positioned on the enlarged head portion of the plate, and a plurality of elongated slots positioned on the elongated portion of the plate;
a plurality of polyaxial calcar fasteners configured to be received in the first and second polyaxial openings and configured to be aimed at a calcar region of the humerus;
a plurality of fixed angle, locking fasteners configured to be received in the plurality of fixed angle openings, respectively, and configured to be aimed at a humeral head of the humerus; and
at least one polyaxial, non-locking fastener configured to be received in one of the plurality of elongated slots to permit dynamic compression of bone and configured to be aimed at a shaft of the humerus,
wherein a width of the enlarged head portion is greater than a width of the elongated portion, and
wherein the second axis extends at an angle to the longitudinal axis such that the enlarged head portion extends upwardly and laterally from the longitudinal axis,
wherein the first and second polyaxial openings and the plurality of fixed angle openings have textured portions in the form of a plurality of helical swept cuts at the transition between an upper tapered portion and a lower tapered portion,
wherein the plurality of helical swept cuts include a series of cuts angled between 50-70°,
wherein the series of cuts create plateaus of material protruding into the respective opening, wherein the plateaus provide positive surfaces for the respective fastener to cut into, reducing axial force necessary to lock the respective fastener to the bone plate.
