Bone Plate

A bone plate for fixation of proximal humerus fractures, comprising:

• an elongated shaft portion having a first width;
• a head portion connected to the shaft portion and having a second width greater than the first width, the head portion and the shaft portion defining a common longitudinal axis;
• at least one first screw hole located in the head portion;
• and
• at least one second screw hole located in the shaft portion, the at least one second screw hole having an elongated perimeter;
• wherein at least one of the first and second screw holes is configured to engage a head of a bone screw to form an angularly stable connection with the bone screw and the elongated perimeter of the at least one second screw hole is formed by first and second overlapping shapes of different size and wherein the plate further comprises a plurality of first screw holes in the head portion, and a plurality of second screw holes in the shaft portion,
• wherein the plurality of first screw holes are asymmetrically arranged about the common longitudinal axis, and
• wherein at least a first pair of the first screw holes is symmetrically disposed about the longitudinal axis so that a first one of the first pair of first holes is located on a first side of the common longitudinal axis and a second one of the first pair of first holes is located on a second side of the common longitudinal axis, and at least a second pair of the first holes is asymmetrically disposed about the longitudinal axis, and
• wherein the plurality of second screw holes are symmetrically arranged about the common longitudinal axis, wherein at least one of an upper surface and a lower surface of the bone plate is divided substantially in half by the common longitudinal axis.

A plate for fixation of proximal humerus fractures, comprising:

• an elongated shaft;
• a head connected to the shaft and having a width greater than a width of the shaft, the head and the shaft being substantially symmetrically divided by a common longitudinal axis;
• a plurality of first screw holes extending through the head asymmetrically with respect to the longitudinal axis, wherein at least a first pair of the first screw holes is symmetrically disposed about the longitudinal axis so that a first one of the first pair of first holes is located on a first side of the common longitudinal axis and a second one of the first pair of first holes is located on a second side of the common longitudinal axis;
• and
• a plurality of second screw holes extending through the shaft substantially symmetrically with respect to the longitudinal axis, a first one of the second screw holes having an elongated perimeter formed by first and second overlapping shapes of different size, one of the first and second screw holes being configured to engage a head of a bone screw to form an angularly stable connection therewith.
