Abstract:
1. A bone plate system for the internal fixation of a fractured bone of a patient, the system comprising: a bone plate including a bone-facing bottom surface, an opposing top surface, a head portion, a shaft portion having a central longitudinal axis, and a thickness between the surfaces, the head portion being wider than the shaft portion, the shaft portion comprising a plurality of closed threaded, locking bone fastener apertures and a plurality of closed non-threaded, non-locking bone fastener apertures; and a plurality of bone fasteners, each fastener comprising a shaft and a head, the heads being dimensioned and configured to threadedly engage the threaded bone fastener apertures to provide a fixed angle locking construct, the heads also being dimensioned and configured to directly engage the non-threaded bone fastener apertures to provide a polyaxial non-locking compressive construct; wherein each of the plurality of threaded apertures is paired together with one of the plurality of the non-threaded apertures to form a plurality of discrete aperture clusters, and wherein a first aperture cluster of the plurality of aperture clusters is positioned about a first side of the central longitudinal axis laterally opposed to a second aperture cluster of the plurality of aperture clusters positioned on a second opposite side of the central longitudinal axis.
