Abstract
An orthopedic fixation assembly for compressing bones includes a bone anchor coupled to a washer. The bone anchor includes a shaft, where the shaft extends along a radius of curvature. The bone anchor also includes a threaded end for anchoring into bone or bone fragments. The washer includes a body and a bore extending therethrough. The washer is coupled to the bone anchor by receiving the shaft within the bore. The washer is compressed against a surface of the underlying bone causing the washer to deform and apply a compressive force on the wire body and on the bone fragments.
Claims54
An orthopedic fixation assembly for compressing bones comprising:
- a bone anchor comprising a shaft;
- and
- a washer comprising a body and a bore extending through the body;
- wherein the shaft extends along a radius of curvature;
- wherein the bore extends through the body along a bore axis;
- and
- wherein the shaft is adapted to be inserted into the bore.
A method for applying compression to bones, comprising:
- providing an orthopedic fixation assembly comprising a bone anchor and a washer;
- wherein the bone anchor comprises a shaft, a threaded end, and a smooth end, wherein the shaft extends along a radius of curvature;
- and
- wherein the washer comprises a body and a bore extending through the body, wherein the body extends through the bore along a bore axis;
- coupling the bone anchor to a drill;
- inserting the shaft into a plurality of bones to anchor the threaded end inside at least one bone of the plurality of bones;
- slideably coupling the bone anchor to the washer by inserting the smooth end into the bore;
- sliding the washer along the shaft until the washer contacts an exterior surface of the at least one bone;
- deforming the washer against the exterior surface of the at least one bone to apply compression to the plurality of bones.
An orthopedic fixation assembly for applying compression to underlying bone, comprising:
- a bone anchor comprising a shaft extending along a radius of curvature;
- and
- a washer comprising a body and a bore extending therethrough;
- wherein the shaft comprises a proximal end, a distal end, and a plurality of external threads extending along the shaft from the distal end to the proximal end less than the entirety of the shaft
- wherein the body resides within the bore along a bore axis;
- and
- wherein the shaft is adapted to be inserted into the bore.
