Abstract
An apparatus for stabilization of a bone fracture site, including a wire that is configured to be positioned through corresponding holes of a first bone and an adjacent second bone; and a tension washer coupled to a first end of the wire, the tension washer rotatable about the first end of the wire, wherein the wire is configured to be positioned through the corresponding holes of the first and the second bone, the tension washer is configured to be positioned proximate a first surface of the second bone, wherein the tension washer includes a first surface having a length longer than a diameter of the corresponding holes of the first and the second bones, wherein the tension washer is configured to rotate such that the first surface of the tension washer abuts the first surface of the second bone.

An apparatus for stabilization of a bone fracture site, the apparatus including:
- a bone fixation plate including a plurality of fastener holes, wherein the bone fixation plate is configured to be coupled to a first bone with one or more fasteners positioned through respective fastener holes of the plurality of fastener holes;
- a wire including a toothed portion;
- a tension washer coupled to a first end of the wire, the wire configured to be positioned through a particular fastener hole of the bone fixation plate and through corresponding holes of the first bone and an adjacent second bone such that the tension washer is positioned proximate a first surface of the second bone opposite a surface of the first bone adjacent the bone fixation plate;
- a cannulated screw configured to be inserted over the wire and through the particular fastener hole to further couple the bone fixation plate to the first bone, the cannulated screw having a top surface configured to face away from the first bone;
- and
- a lock washer including a flexible portion with a first lock-washer surface configured to face toward the first bone and a base portion with a second lock-washer surface configured to face away from the first bone, wherein the flexible portion is configured to engage the toothed portion of the wire, and the first lock-washer surface of the flexible portion is configured to abut the top surface of the cannulated screw to provide tension to the wire.
An apparatus for stabilization of a bone fracture site, the apparatus comprising:
- a wire configured to be positioned through corresponding holes of a first bone and an adjacent second bone, the wire including a toothed portion;
- a tension washer rotatably coupled to a first end of the wire, and configured to be positioned proximate a first surface of the second bone, wherein the tension washer is configured to rotate about the first end of the wire such that a first surface of the tension washer abuts the first surface of the second bone;
- a cannulated screw configured to be inserted over the wire and into to the first bone;
- and
- a lock washer including a flexible portion with a first lock-washer surface configured to face toward the first bone and a base portion with a second lock-washer surface configured to face away from the first bone, wherein the flexible portion is configured to engage the toothed portion of the wire, and the first lock-washer surface of the flexible portion of the lock washer is configured to abut a top surface of the cannulated screw to provide tension to the wire.
