Osteotomy systems, devices and methods
Osteotomy systems, devices, and methods for using the osteotomy systems are disclosed. The osteotomy system including an alignment device, at least one k-wire for insertion into the alignment device, and a cut guide with at least one hole for receiving at least one k-wire and a slot for receiving a saw blade. An osteotomy kit including an alignment device, cut guide, and position rotation device. The alignment device, cut guide, position rotation device, and bone plate are also disclosed. Finally, a method for fusing bones using the osteotomy system is also disclosed.
1. A surgical method, comprising:
creating an incision;
exposing a bone with a deformity;
using an alignment device for determining a rotation angle for the bone, wherein the alignment device comprises a plurality of openings, at least one of which corresponds to the rotation angle;
using a cut guide to cut the bone into two bone pieces;
using a rotation device to rotate a first bone piece of the two bone pieces relative to a second bone piece of the two bone pieces to a desired angle of rotation;
securing the two bone pieces; and
closing the patient's incision.
2. The surgical method of claim 1 , further comprising:
positioning a foot with the bone onto a foot plate of a foot plate guide;
inserting a first k-wire through a foot plate k-wire guide of the foot plate guide; and
removing the foot plate k-wire guide and the foot plate from the foot.
3. The surgical method of claim 2 , wherein using the alignment device for determining the rotation angle for the bone comprises:
placing the alignment device onto the bone, wherein the alignment device is placed over the first k-wire;
determining a rotation angle for the bone;
selecting a second opening in the alignment device that corresponds to the determined rotation angle;
inserting a second k-wire into the second opening in the alignment device; and
removing the alignment device and the first k-wire.
4. The surgical method of claim 1 , wherein using the alignment device for determining the rotation angle for the bone comprises:
placing the alignment device onto the bone;
inserting a first k-wire into a first opening in the alignment device determining a rotation angle for the bone;
selecting a second opening in the alignment device that corresponds to the determined rotation angle; and
inserting a second k-wire into the second opening in the alignment device; and removing the alignment device and the first k-wire.
5. The surgical method of claim 1 , wherein using the cut guide to cut the bone into the two bone pieces comprises:
obtaining the cut guide;
determining an osteotomy cut angle;
selecting a hole in the cut guide that corresponds to the determined osteotomy cut angle;
sliding the selected hole of the cut guide over a k-wire inserted into the bone using the alignment device;
fixing the cut guide to the bone along an axis of the bone with a fixation device; and
cutting the bone into the two bone pieces.
6. The surgical method of claim 5 , wherein cutting the bone into two bone pieces comprises:
obtaining a sagittal saw blade;
inserting the saw blade through a slot in the cut guide to cut the bone;
cutting at least a portion of the bone; and
removing the fixation device, the k-wire, and the cut guide.
7. The surgical method of claim 6 , further comprising:
completing a cut of the bone after removal of the fixation device, the k-wire, and the cut guide.
8. The surgical method of claim 1 , wherein using the rotation device to rotate the first bone piece relative to the second bone piece to the desired angle of rotation comprises:
obtaining the rotation device;
positioning the rotation device on the cut bone; and
rotating the first bone piece on a distal end with respect to the second bone piece on a proximal end to the desired angle of rotation on the rotation device.
9. The surgical method of claim 8 , wherein rotating the first bone piece with respect to the second bone piece is through an oblique plane.
10. The surgical method of claim 1 , wherein using the rotation device to rotate the first bone piece relative to the second bone piece to the desired angle of rotation comprises:
obtaining the rotation device;
sliding the rotation device onto a k-wire inserted into the bone using the alignment device;
rotating the first bone piece on a distal end of the bone to the desired angle of rotation; and
removing the k-wire.
11. The surgical method of claim 1 , wherein using the rotation device to rotate the first bone piece relative to the second bone piece to the desired angle of rotation comprises:
obtaining the rotation device;
sliding the rotation device onto a first k-wire inserted into the bone using the alignment device;
inserting a second k-wire into the rotation device;
inserting a third k-wire into the rotation device;
removing the second k-wire and rotation device; and
rotating the third k-wire to align the third k-wire with the first k-wire.
12. The surgical method of claim 1 , wherein securing the two bone pieces comprises:
securing the two bone pieces with at least one of a plate and a crossing screw.
13. The surgical method of claim 12 , wherein securing the two bone pieces comprises:
fixing a plate to the two bone pieces; and
inserting a crossing screw across the two bone pieces.
14. The surgical method of claim 13 , wherein the crossing screw is inserted with an alignment guide.
15. The surgical method of claim 14 , wherein the alignment guide is coupled to the plate before insertion of the crossing screw.
16. The surgical method of claim 1 , wherein the bone is a first metatarsal bone.
17. The surgical method of claim 16 , further comprising:
calculating an intermetatarsal angle, comprising:
measuring a divergence between the first metatarsal bone and a second metatarsal bone; and
measuring an angle to be corrected to determine the degrees to place a head of the first metatarsal over a sesamoid complex.
18. The surgical method of claim 1 , wherein exposing the bone comprises:
performing a transarticular capsulotomy through a medial approach.
19. The surgical method of claim 1 , further comprising:
relocating the bone above sesamoids.
20. The surgical method of claim 1 , wherein the deformity is a hallux valgus deformity.
