Abstract:
1. A bone plate, comprising: a) a proximal plate portion lying substantially in a first plane, the proximal plate portion having a proximal plate thickness extending from a top proximal plate surface to a bottom proximal plate surface with at least one threaded hole formed through the proximal plate thickness; b) a distal plate portion lying substantially in a second plane, the distal plate portion having a distal plate thickness extending from a top distal plate surface to a bottom distal plate surface with at least one threaded hole formed through the distal plate thickness; c) a transition region, connecting the proximal plate portion lying in the first plane to the distal plate portion lying in the second plane, wherein the first plane is substantially parallel to the second plane; and d) wherein at least one of the threaded holes in either the proximal plate portion or the distal plate portion is an overlapping threaded hole comprising an unthreaded upper portion extending from an oval shaped opening at either the top proximal plate surface or the top distal plate surface part way through the respective thickness thereof to a threaded lower portion having an hourglass shape extending from where the upper portion ends at the hourglass shape to the bottom proximal plate surface or the bottom distal plate surface with threaded surfaces of the overlapping holes meeting each other at a threaded overlap forming the hourglass shape, the threaded lower portion being adapted to lock with threads of a corresponding bone screw in either one or the other of the overlapping holes.
