Abstract
A bone plate for fixation of proximal humerus fractures comprises an elongated shaft portion having a first width and a head portion connected to the shaft portion having a second width greater than the first width. The head portion and the shaft portion define a common longitudinal axis. At least one first screw hole may be located in the head portion, and at least one second screw hole may be located in the shaft portion. At least one of the first and second holes is configured to engage a head of a bone screw to form an angularly stable connection with the bone screw.

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;
- at least one second screw hole located in the shaft portion;
- 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.
A bone plate for fixation of a fractured bone, the bone plate comprising:
- an elongated shaft portion and a widened head portion, the shaft portion and the head portion defining a common longitudinal axis extending substantially centrally along the bone plate;
- a first pair of screw holes located in the head portion, the first pair of holes include a first hole having a first central axis and a second hole having a second central axis, wherein the first and second holes are asymmetrically disposed about the longitudinal axis;
- a second pair of screw holes located in the head portion, the second pair of holes include a third hole having a third central axis and a fourth hole having a fourth central axis, wherein the third and fourth holes are symmetrically disposed about the longitudinal axis;
- wherein the first central axis lies in a first plane and the second central axis lies in a second plane that is substantially parallel to the first plane, further wherein when the first central axis and the second central axis are projected onto a third plane substantially orthogonal to the longitudinal axis, the first central axis and the second central axis intersect to form an acute angle.
