Surgical systems and methods including aligning guides for performing a percutaneous bunion correction
Surgical systems and methods for correcting a bunion percutaneously including aligning guides are provided herein. At least one embodiment includes a handle including a rod with a first end including a first longitudinal axis and a second end including a second longitudinal axis offset from the first longitudinal axis. The handle can couple to a gadget including a leg that couples to the handle, and a translator that extends and retracts the leg. The gadget can also a slide with a guide body to guide a guide wire for accurate placement of a screw. The surgical system can also include a periscope to assist in pre-visualization of the screw placement.
1 . A surgical apparatus comprising:
a handle configured to be couplable to a gadget, the handle comprising:
a rod including a first end and a second end opposite the first end;
the first end comprising a first longitudinal axis and the second end comprising a second longitudinal axis, wherein the first longitudinal axis is offset from the second longitudinal axis by an extension; and
a coupler coupled to the rod the coupler comprising a threaded first end;
wherein the gadget comprises;
a leg comprising:
a slot including an open side, a slot longitudinal axis, and a slot threaded first end, wherein the slot threaded first end is configured to conform to the coupler threaded first end to facilitate the coupling of the handle to the leg;
a slide slidably coupled to a body; and
a guide body coupled to the slide and configured to position a guide wire,
wherein the guide body is configured to be rotatable.
2 . The surgical apparatus of claim 1 , further comprising:
a translator comprising the passage and a post, wherein the passage and the post include complimentary threads such that rotating the post within the passage in a first rotational direction controls the extension of the leg, and rotating the post within the passage in a second rotational direction controls the retraction of the leg.
3 . The surgical apparatus of claim 2 , wherein the slide includes a slide lock configured to prevent the slide from moving when the slide lock is engaged.
4 . The apparatus of claim 2 , further comprising a rotation arm removably couplable to the body and configured to facilitate the rotation of a first bone portion, wherein the rotation arm comprises at least one notch configured to hold a k-wire.
5 . The surgical apparatus of claim 4 , wherein the rotation arm is configured to facilitate the rotation of a metatarsal capital fragment.
6 . The surgical apparatus of claim 2 , further comprising a periscope configured to couple to the body and hold a k-wire in the same orientation that a guide wire sheath will guide a screw.
7 . The surgical apparatus of claim 6 , wherein the periscope further comprises a radiograph alignment tool.
8 . The surgical apparatus of claim 1 , further comprising a radiograph positioning tool including two metal rods positioned within the slide such that they appear as one rod when viewed laterally.
9 . The surgical apparatus of claim 1 , further comprising a guide wire sheath coupled to the body, wherein the guide wire sheath is configured to guide a k-wire to a desired position.
10 . The surgical apparatus of claim 1 , wherein the handle further comprises:
a coupler first end and a coupler second end opposite the coupler first end; and
a head coupled to the rod second end and couplable to the coupler second end.
11 . The surgical apparatus of claim 1 , wherein the first longitudinal axis and the second longitudinal axis are parallel.
12 . The apparatus of claim 1 , wherein the extension comprises an extension length in the range of 2 mm-50 mm inclusive.
13 . A method comprising the steps of:
providing an apparatus, wherein the apparatus comprises:
a rod including a first end and a second end opposite the first end;
the first end including a first longitudinal axis and the second end including a second longitudinal axis, wherein the first longitudinal axis and the second longitudinal axis are not coextensive;
a coupler coupled to the rod;
a leg comprising:
a slot including an open side, a slot longitudinal axis, and a slot threaded first end, wherein the slot threaded first end is configured to conform to the coupler threaded first end to facilitate the coupling of the handle to the leg;
a slide slidably coupled to a body; and
a guide body coupled to the slide and configured to position a guide wire, wherein the guide body is configured to be rotatable; and
inserting the rod first end into a proximal metatarsal bone portion.
14 . The method of claim 13 , further comprising:
placing the slot onto the rod and coupling to coupler to the leg.
15 . The method of claim 14 , further comprising providing a buttress coupled to the body and abutting a first bone.
16 . The method of claim 15 , further comprising checking the position of the gadget relative to the first bone by viewing the radiograph positioning tool from a lateral view, wherein the radiograph positioning tool comprises at least two bars within the body that will appear as one bar when viewed from a lateral position on a radiograph when the gadget is in a desired position relative to the first bone.
17 . The method of claim 16 , further comprising providing a translator, wherein the translator extends and retracts the leg and handle relative to the buttress wherein the extension or retraction of the leg is controlled by the translator.
