Reduction of a bone fragment of a bone fracture at a bone fracture site is accomplished through a minimally invasive access passage utilizing instruments having a working head actuated from a location remote from the bone fracture site, between an insertion configuration dimensioned and configured to present a minimal cross-sectional area for ready passage through the minimally invasive access passage and a working configuration dimensioned and configured to establish an essentially rigid working face of substantially greater cross-sectional area than the minimal cross-sectional area. The working head is actuated into the working configuration and manipulated from the remote location while in the working configuration to engage the working face with the bone fragment and manipulate the bone fragment into an anatomically appropriate reduced position at the bone fracture site.

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.
