Abstract
Devices, systems, instruments, and methods for promoting healing and stability for bone fractures. Large fragment plating systems with a variety of plate styles allow for reduction of the fracture to achieve primary bone healing. Compression and/or distraction may be applied to the bone fragments during the procedure with an external instrument, such as a fracture reduction instrument configured to restore the fracture while implanting the plate.
Claims6
A bone stabilization system for reducing a fracture between two bone fragments, the system comprising:
- a bone plate having an elongate body extending between two ends, the bone plate having a shaft portion and a tapered region decreasing in thickness from the shaft to one end, a plurality of fastener openings defined therethrough including one polyaxial opening extending through the tapered region, and polyaxial openings and compression slots extending through the shaft portion;
- and
- a fracture reduction instrument having a translation arm and a hook arm pivotably coupled together, the translation arm has a screw engaging projection configured to engage a bone screw and the hook arm has a hook configured to engage the bone plate, wherein the fracture reduction instrument is configured to apply compression or distraction to the bone plate to reduce the fracture,
- wherein a guide wire hole is defined through the tapered region, and a swept cut connects the polyaxial opening to the guide wire hole on an underside of the bone plate.
