Abstract: 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.

Abstract: A method of bone fixation comprises the steps of implanting at least one first fixation element into a respective first anatomical body such that a portion of the first fixation element extends out from an exterior surface of the first anatomical body, and implanting at least one second fixation element into a respective second anatomical body that is adjacent the first anatomical body, such that a portion of the second fixation element extends out from an exterior surface of the second anatomical body. A hardenable material is applied to the portion of each of the fixation elements that extends out from the exterior surface of the respective anatomical body when the hardenable material is in an unhardened state. The hardenable material is hardened such that the hardenable material forms a hardened construct together with the bone fixation elements that bridges the anatomical bodies.
