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.
Claims13
A fracture reduction instrument for reducing a bone fracture, the instrument comprising:
- first and second pivoting arms extending from a proximal end to a distal end, the first and second pivoting arms having handles near the proximal ends, the first pivoting arm having a screw engaging projection and the second pivoting arm having a plate engaging hook at the respective distal ends, and a locking member positioned between the proximal ends of the first and second pivoting arms,
- wherein the locking member includes a shaft with a buttress thread positionable through a pivoting locking assembly having a locking ring retained to a central ring and first and second female thread pieces pivotably coupled to the central ring and having teeth engageable with the buttress thread,
- wherein when the handles are squeezed together, the pivoting locking assembly translates along the shaft in a forward motion and prevents any backward translation, thereby locking the relative position of the first and second pivoting arms.
A method for reducing a fracture, the method comprising:
- providing a fracture reduction instrument configured to temporarily attach to a bone plate and temporarily engage a bone screw to apply compression and/or distraction to the fracture;
- and either:
- (a) compressing the fracture, which includes:
- (a1) positioning the bone plate against an exterior surface of a long bone and across a fracture;
- (a2) securing the bone plate to a bone fragment on one end of the fracture by attaching a first fastener through a polyaxial opening in the bone plate;
- (a3) hooking the fracture reduction instrument under a screw hole on an opposite side of the fracture;
- (a4) inserting a second fastener into a compression slot nearest to the instrument;
- (a5) manipulating the instrument to translate the un-fixed side of the bone plate;
- (a6) fixing the compression generated through the instrument by inserting a third fastener into any holes on the same side of the fracture as the instrument;
- (a7) removing the instrument;
- (a8) optionally removing the second fastener in the compression slot or fully seating the second fastener into bone;
- or
- (b) distracting the fracture, which includes:
- (b1) positioning the bone plate against an exterior surface of a long bone and across a fracture;
- (b2) securing the bone plate to a bone fragment on one end of the fracture by attaching a first fastener through a polyaxial opening in the bone plate;
- (b3) hooking the fracture reduction instrument under a screw hole on a far end of the bone plate on an opposite side of the fracture;
- (b4) inserting a second fastener into the bone outside of the bone plate;
- (b5) manipulating the instrument to translate the bone, thereby reducing the fracture;
- (b6) fixing the distraction generated by inserting a third fastener into any holes on the same side of the fracture as the instrument;
- (b7) removing the instrument;
- and (b8) optionally removing the second fastener, fully seating the second fastener into the bone, or replacing the second fastener with a shorter screw.
