Bone align and joint preparation device and method
A bone displacement system includes an anchoring portion, a tool engaging portion, a compression distraction mechanism, a lateral body and a distal body. The anchoring portion has an aperture for receiving a wire to connect the anchoring portion to a proximal bone. The anchoring portion is connectable to a downwardly depending member for holding a tissue portion. The tool engaging portion is connected to the anchoring portion and is configured to connect a tool thereto. The compression-distraction mechanism is connected to the anchoring portion. The lateral body is connected to the compression-distraction mechanism and engageable with a lateral bone. The distal body is connected to the compression-distraction mechanism. The distal body has an aperture for receiving a wire to connect the distal body to a distal bone. The compression-distraction mechanism is configured to move the anchoring portion relative to the distal body.
1. A bone displacement system comprising:
a mobile portion and an arm, such that the mobile portion is movable along the arm;
a movable trolley positioned laterally relative to the mobile portion, the movable trolley comprising a downwardly depending member configured to engage a first metatarsal;
a lateral extension mechanism movable laterally and comprising a receiving cavity;
a paddle in the receiving cavity and configured to abut a side of a second metatarsal; and
apertures configured to receive wires to attach the system to bones to accommodate displacement of said first metatarsal and second metatarsal.
2. The system of claim 1 wherein the movable trolley comprises a plantar-dorsal adjustment mechanism configured to engage the first metatarsal and configured to adjust a plantar-dorsal position of the first metatarsal relative to the system.
3. The system of claim 2 wherein said plantar-dorsal adjustment mechanism comprises a threaded member received in a threaded receiving portion of said movable trolley such that said threaded member is rotatable in said receiving portion to apply a vertical force to the first metatarsal.
4. The system of claim 1 wherein said paddle is a second downwardly depending portion for contacting the second metatarsal, and the second metatarsal is a lateral bone.
5. The system of claim 4 wherein said receiving cavity is a lateral holding portion connected to the second downwardly depending portion and movably connected to a rail to allow said lateral holding portion to move laterally relative to a longitudinal axis of said arm.
6. The system of claim 5 wherein said lateral extension mechanism comprises a screw engaging the rail and the lateral holding portion to allow movement of the lateral holding portion and the lateral bone relative to the first metatarsal when a user drives said screw, the movable trolley is connected to the first metatarsal, and the second downwardly depending member engages the lateral bone.
7. The system of claim 1 further comprising a screw engageable by a user to cause movement of the mobile portion relative to the arm to cause a compression or a distraction of a proximal bone relative to the first metatarsal.
8. The system of claim 1 wherein the lateral extension mechanism is moveably engaged with a rail and the rail having a rail longitudinal axis, the arm having an arm longitudinal axis, said rail longitudinal axis and said arm longitudinal axis being angled at less than perpendicular to each other.
9. A method for use in bone displacement, comprising:
providing the bone displacement system of claim 1 ; and
performing a surgery of a foot using the bone displacement system.
