Device and surgical technique for foot surgery
A correction clamp assembly that permits a physician to surgically correct a bunion or similar deformity is provided. The assembly includes an elongate bridge, as well as first and second blocks slidably or rotatably connected to the elongate bridge. More specifically, first block is configured to slide along a slot formed in the elongate bridge, as well as rotate relative thereto. Additionally, the second block is configured to rotate relative to the elongate bridge. First and second pins may be configured to extend through the first and second block, and then into various pieces of bone. Once a cut is made in a portion of joint or bone, the pins can thereafter be moved towards and away from one another to position the respective pieces of bone in a desired location. Locking screws may also be provided to releasably secure the blocks relative to the bridge.

wherein the second block further comprises:
a main body;
a tube with a first opening extending therethrough along a first axis;
a second opening extending through the body along a second axis.
2. The correction clamp assembly of claim 1 , further comprising:
a first pin associated with the first block; and
a second pin associated with the second block.
3. The correction clamp assembly of claim 2 , wherein the first block slides and rotates relative to the slot; and
wherein the second block rotates relative to the first opening.
4. The correction clamp assembly of claim 3 , further comprising:
at least one first block locking screw configured to releasably secure the first block relative to the elongate bridge in a lateral translational direction;
at least one second block locking screw configured to releasably secure the second block relative to the elongate bridge in a rotational direction.
5. The correction clamp assembly of claim 4 , wherein the first block further comprises at least one guide rail configured to guide movement of the first block relative to the elongate bridge.
6. The correction clamp assembly of claim 4 , wherein the second pin is configured to be secured to a first metatarsal; and
wherein the first pin is configured to be secured to a second metatarsal.
7. The correction clamp assembly of claim 6 , wherein the second pin is configured to be manipulated to move the first metatarsal towards the second metatarsal.
8. The correction clamp assembly of claim 1 , wherein the first block further comprises at least one guide rail configured to guide movement of the first block relative to the elongate bridge.
9. The correction clamp assembly of claim 1 , wherein the first block further comprises a gripping section and an identifier;
wherein the second block further comprises a gripping section and an identifier;
wherein the elongate bridge includes first and second identifiers;
wherein the first block identifier is aligned with the first identifier of the elongate bridge; and
wherein the second block identifier is aligned with the second identifier of the elongate bridge.
10. A method of performing a medical procedure comprising the steps of:
inserting a first pin through a second metatarsal;
inserting the first pin through a first block associated with a correction clamp;
inserting a second pin through a first metatarsal;
inserting the second pin through a second block associated with the correction clamp;
creating a corrective cut in one or more of a bone and a joint;
manipulating the second pin to move the second block and the first metatarsal relative to the second metatarsal;
reaching a desired location of the first metatarsal; and
securing the first metatarsal in place.
11. The method of performing a medical procedure of claim 10 , further comprising the steps of:
sliding the first block relative to a bridge associated with the correction clamp; and
rotating the second block relative to the bridge.
12. The method of performing a medical procedure of claim 11 , further comprising the steps of:
sliding the first block relative to a slot formed in the bridge; and
rotating the second block about a bridge hole formed in the bridge.
13. The method of performing a medical procedure of claim 11 , further comprising the step of sliding at least one guide rail associated with the first block to enable movement of the first block relative to the bridge.
14. The method of performing a medical procedure of claim 11 , further comprising the steps of:
securing the first block in place relative to the bridge using a first locking screw; and
securing the second block in place relative to the bridge using a second locking screw.
15. The method of performing a medical procedure of claim 10 , further comprising the steps of:
inserting the first pin through an opening in a tube that extends through the first block; and
inserting the second pin through an opening in a tube that extends through the second block.
16. The method of performing a medical procedure of claim 10 , further comprising the steps of:
pressing the second pin towards the first pin; and
moving the first metatarsal to the desired location.
17. The method of performing a medical procedure of claim 16 , further comprising the steps of:
releasably securing first block into place relative to a bridge associated with the corrective clamp once the first metatarsal is in the desired location; and
releasably securing the second block into place relative to the bridge associated with the corrective clamp once the first metatarsal is in the desired location.
18. A kit for an osteotomy or joint fusion medical procedure comprising:
a bridge comprising a body, a first opening formed in the body, and an elongate slot formed in the body;
a first block configured to be secured to the bridge along the slot;
a second block configured to be secured to the bridge about the first opening;
a plurality of pins; and
wherein the first block further comprises:
a main body;
a tube with a first opening extending therethrough along a first axis;
a second opening extending through the body along a second axis; and
wherein the second block further comprises:
a main body;
a tube with a first opening extending therethrough along a first axis;
a second opening extending through the body along a second axis.
19. The kit of claim 18 , further comprising a plurality of locking screws configured to releasably secure the first block and the second block in place relative to the bridge.
20. The kit of claim 18 , further comprising a cutting saw for creating a corrective cut or preparing a joint in one or more of bone and a joint; and
