Abstract
A bone plate system for joining together adjacent bone parts of a surgical patient includes a bone plate having a first slot defining a first centerline axis, a second slot defining a second centerline axis, and a third slot defining a third centerline axis. The first, second and third slots are disposed in a triangular arrangement and simultaneously positionable over each of three adjacent bone parts. Each of a first compressing screw, a second compressing screw and a third compressing screw has a threaded shank for passage through the first, second and third slots, respectively, and engagement into the underlying bone part. Each of the first, second and third compressing screws also has a screw head configured to forcefully interact during insertion until fully seated with the first, second and third slot, respectively, thereby urging the first, second and third compressing screws to move along the first, second and third centerline axis, respectively, such that the three bone parts are multi-axially compressed towards each other.
