Bones fracture in any number of various ways and, in order to properly reduce a fracture, it may be necessary to place compression screws in any number of combinations along a bone plate to bring the various bone fragments together. A bone plate is provided with an optimal number and combination of threaded holes and non-threaded holes. In embodiments, the bone plate comprises one or more “hole pairs” in which a non-threaded hole and a threaded hole are placed adjacent to one another. The use of hole pairs enables a surgeon to place a compression screw and a locking screw in close proximity, facilitating both bone reduction and bone plate stabilization in a proximate location on the bone plate. In embodiments, the bone plate has an optimal thickness that promotes structural integrity while maximizing the number and combination of holes and reducing the profile of seated screws.

The bone plate of claim 1, wherein the non-threaded hole is non-cylindrical. 12. A bone plate for reducing a bone fracture, comprising: a top surface and a bottom surface; andat least one hole pair including: a threaded hole passing through the top surface, through a substantially solid interior region and out the bottom surface of the bone plate, threads of the threaded hole extending from the top surface, wherein the threaded hole accepts a first screw; anda non-threaded hole passing through the top surface, through the substantially solid interior region and out the bottom surface of the bone plate, wherein the non-threaded hole accepts a second screw, wherein the threaded hole and the non-threaded hole are distinct holes in close proximity to one another. 13. The bone plate of claim 12, wherein at least a portion of the threaded hole overlaps at least a portion of the non-threaded hole. 14. The bone plate of claim 12, wherein the number of hole pairs is maximized along a longitudinal axis of the bone plate. 15. The bone plate of claim 14, wherein the bottom surface of the bone plate includes scallops adjusted to maximize the number of hole pairs along the longitudinal axis of the bone plate. 16. The bone plate of claim 12, wherein a screw seated in one of the non-threaded hole or the threaded hole has a reduced profile. 17. The bone plate of claim 12, wherein the bone plate concurrently accepts the first screw in the threaded hole and the second screw in the non-threaded hole. 18. The bone plate of claim 12, wherein an internal geometry of the non-threaded hole accepts the second screw at a plurality of different angles. 19.
