Abstract
A bone fixation system having a plate with an axle and a blade or “beam” configured to engage with the axle and reside proximate to a subchondral fragment of bone in upon installation of the plate. The beam is operable to rotate about the axle on the plate and reposition the subchondral fragment of bone.
Claims13
A method of repositioning a displaced bone fragment, the method comprising the steps of:
- attaching a rod to a beam, wherein the rod is part of a tool having internal and external portions that are rotatable relative to each other to affect engagement and disengagement of the beam with the rod, and wherein the rod is configured to be at least partially received by the beam;
- causing the beam to securely engage a portion of a bone fixation plate using the rod;
- and
- causing the beam to rotate about the portion of the plate by advancing a positioner at least partially through an opening in the plate.

A method of treating a bone fracture by altering angulation of a fracture fragment of a bone using a bone fixation system, the method comprising the steps of:
- securing a beam to a bone fixation plate, wherein the plate has at least one beam engagement feature used for securing the beam to the plate, and wherein the beam has an end portion with (i) a plate engagement feature operable to rotatably engage the at least one beam engagement feature of the plate, (ii) at least one bone engagement feature operable to engage a portion of a bone, and (iii) a retention feature operable to prevent detachment of the beam from the plate;
- securing the plate to the fracture fragment of the bone;
- advancing a screw through the plate to abut the beam;
- causing the beam to pivot with respect to the plate by further advancing the screw through the plate;
- wherein the beam includes a receiver comprising a hole extending at least partially through the beam that is operable to receive a tool, and wherein the hole is sized and shaped to threadedly receive a terminally-threaded inserter/extractor rod of the tool, the rod configured to facilitate the securing of the beam to the plate.
