Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

As will be described below, the present invention includes systems and methods for correcting a deformity of the human foot.

As depicted in FIGS. 1-4 and 34-35, a post drill guide 2000 may be engaged with a foot 10 (i.e., after appropriate surgical preparation) such that a paddle 2100 thereof is located in an articular space between a medial cuneiform 20 and a first metatarsal 30 of foot 10. Guide 2000 also includes a bore 2300 for receiving a K-wire 2400 (e.g., a 2 mm K-wire) therethrough from a top side thereof toward a bottom side thereof adjacent foot 10. Drill guide 2000 may include gripping portions 2010 and paddle 2100 may be located longitudinally offset from a longitudinal center 2015 of guide 2000 relative to a longitudinal dimension of a bottom side 2035 of drill guide 2000. A cavity 2020 may be bounded by inner surfaces of gripping portions 2010.

As depicted in FIG. 3, a longitudinal dimension of bottom side 2035 of drill guide 2000 may be aligned with, or substantially parallel to, a longitudinal axis 32 of first metatarsal 30. For example, K-wire 2400 may be loosely placed into bore 2300 of Post Drill Guide 2000 to allow an angle of the K-Wire to be observed to determine if the K-wire is both parallel to a tarsal-metatarsal (TMT) joint 33 and in a middle of a long axis of medial cuneiform 20. For example, the K-wire may generally be placed dorsal-lateral to plantar medial. The K-wire may be adjusted to allow such alignment and then the K-wire may be inserted through bore 2300 of post drill guide 2000 into foot 10 as depicted in FIG. 4. The placement of the K-wire, as described, establishes a reference point for a procedure for correcting a deformity of foot 10 and establishes a primary plane between the two bones.

As depicted in FIG. 5, the surgeon may remove post drill guide 2000, leaving K-wire 2400 in the bone (i.e., foot 10). A cut guide 600 may be placed over K-wire 2400 via an anchoring hole 610 (FIG. 10) extending vertically through cut guide 600 receiving the K-wire. As depicted in FIGS. 6-7, a stem 630 of cut guide 600 is connected to a cut body 640 thereof and has a longitudinal dimension or axis 632 aligned with or extending parallel to axis 32 of first metatarsal 30.

Cut guide 600 may include multiple slots 650 (e.g., 4) for receiving a saw blade (e.g., a saw 170) to allow a cut of a bone (e.g., cuneiform 20) attached to cut guide 600 or a bone (e.g., first metatarsal 30) coupled to such cut guide. Slots 650 may have longitudinal dimensions about, or at least approximately, perpendicular to a longitudinal dimension of a stem 630 of cut guide 600.

A proximal anchoring portion 602 may extend proximally away from stem 130 and may have a longitudinal axis 601 aligned with longitudinal axis 132 of stem 130. Anchoring portion 602 may include and have interior surfaces bounding anchoring hole 610 extending vertically therethrough from a top side thereof toward foot 10 as depicted in FIGS. 7-8, for example.

As depicted in FIGS. 7-10, a K-wire 2405 (e.g., a 2 mm K-wire), similar to K-wire 2400, may be inserted through a distal locking hole 660 in stem 630 into bone (i.e., foot 10) to pin the cut guide in place such that a proximal end 31 of the metatarsal may be immobilized relative to cuneiform 20. Distal locking hole 660 may be aligned at a non-perpendicular angle relative to a longitudinal dimension of stem 630 as depicted in FIGS. 9-10. For example, a top end of the K-wire received in locking hole 660 may be located further distally than a bottom end thereof such that the top portion is angled away from K-wire 2400 and/or anchoring portion 200 to securely fasten cut guide 100 relative to first metatarsal 30. Such alignment of distal locking hole 660 and insertion of K-wire 2400 therethrough into a bone (e.g., into first metatarsal 30) at an angle greater than or less than perpendicular may allow a frictional force to be applied on K-wire 2400 in a longitudinal direction relative to axis 632 to further inhibit movement and secure K-wire 2400 and stem 630 to the bone compared to a perpendicular or approximately perpendicular locking hole. In another example, such a perpendicular or approximately perpendicular locking hole may be utilized in place of distal locking hole 660.

As described above, an axis of locking hole 660 may be aligned relative to a longitudinal dimension of stem 630 at an angle greater than or less than perpendicular. Further, additional locking holes 670 may be located on a proximal end 665 of cut guide 600 or on a distal end 675 of stem 630 to fix cut guide 600 in a particular position as described above relative to locking hole 660. Such additional locking holes may be oriented at various angles relative to an axis of stem 630. For example, a top end of a K-wire may be received in a distal locking hole 674 of locking holes 670 angled away from a bottom thereof such that the top end is more proximal than the bottom (i.e., opposite to an alignment described relative to locking hole 660) which may inhibit movement of cut guide 600 relative to the bone (i.e., foot 10) attached to the K-wire as depicted in FIG. 10. Further, as depicted in FIG. 10, stem 630 may include a stem locking hole 615 configured (e.g., shaped and dimensioned) to receive a K-wire 2403 therethrough to further inhibit movement between cut guide 600 and the bone portions, (i.e., cuneiform 20 and first metatarsal 30).

As depicted for example in FIG. 10, slots 50 may be formed in cut body 640 between stem 630 and anchoring portion 602. Slots 50 may include a first proximal slot 652, a second proximal slot 654, a first distal slot 656 and a second distal slot 658 configured (e.g., shaped and dimensioned) to receive a saw to allow a cutting and removing of a portion of medial cuneiform 20 and/or first metatarsal 30, for example.

Cut guide 600 may be attached to a bone (e.g., cuneiform 20) via a K-wire (e.g., K-wire 2400) being received in hole 610 such that the K-wire may extend therethrough and may be inserted in the bone. Cut guide 600 may remain attached to a bone (e.g., cuneiform 20) during multiple cuts using a saw (e.g., a saw 170) via slots 650. As depicted in FIG. 9, for example, a cut may be made to a bone (e.g., first metatarsal 30) through first distal slot 656 of slots 650 to remove a portion (e.g., 1.5 mm in a direction parallel relative to axis 32) from the bone or through second distal slot 658 of slots 650 to remove a larger portion (e.g., 3.0 mm) from the bone while a K-wire (e.g., K-wire 2300) is received in opening or anchoring hole 610. In a further example, a cut may be made to a bone (e.g., cuneiform 20) through a first proximal slot 652 of slots 650 to remove a portion (e.g., 1.5 mm in the direction parallel relative to axis 32) from the bone or through second proximal slot 654 of slots 650 to remove a larger portion (e.g., 3.0 mm) from the bone while a K-wire (e.g., K-wire 2400) is received in opening or hole 610.

Further, in an example, cut guide 600 may be pinned on a proximal end thereof (i.e., end 665) by K-wire 2400 received in hole 610 and may be rotated about K-wire 2400 to locate cut guide 600 in differing orientations to provide bone portions having different shapes which may be removed from the space between a metatarsal (e.g., first metatarsal 30) and a cuneiform (e.g., cuneiform 20) to provide a desired aperture or cavity to facilitate a desired realignment of bone (e.g., cuneiform 20 and first metatarsal 30). Cut guide 600 may be used in a similar manner on other portions of a foot or other portion of a body. For example, one or more of slots 650 may thus be utilized to make various cuts at various angles to remove portions of a bone (e.g., of foot 10) as desired to best align bone portions (e.g., cuneiform 20 and first metatarsal 30).

FIGS. 10-11 depict cut guide 600 having a stem (e.g., stem 630) and anchoring portion (e.g., anchoring portion 602) offset in a transverse or medial-lateral direction (i.e., bottom to top as depicted in FIG. 11) relative to a central axis in a medial-lateral direction aligned about, or approximately, perpendicular to a longitudinal dimension of body 640 and/or slots 650.

As depicted in FIG. 12, K-wire 2405 may be removed from foot 10 and cut guide 600 such that cut guide 600 may be connected to foot 10 only via K-wire 2400. Cut guide 600 may be rotated about K-wire 2400 such that longitudinal axis 632 of stem 630 is aligned with a desired axis of first metatarsal 30 relative to a first proximal phalange 35. As depicted in FIG. 13, longitudinal axis 632 of stem 630 may also be aligned such that longitudinal axis 632 is in a desired position (e.g., parallel, angled at a particular dimension, or otherwise) relative to a longitudinal axis 34 of a second metatarsal 36. For example, longitudinal axis 632 may be aligned parallel to longitudinal axis 34 of second metatarsal 36 such that a cut may be made (e.g., using saw 170 and one of slots 650) perpendicular to a desired axis of first metatarsal 30. Another of slots 650 may be utilized to change (e.g., increase or decrease) an amount of bone resected (e.g., via from a distal portion 21 of medial cuneiform 20 (FIGS. 12-15)). For example, a saw (e.g., saw 170) may be utilized to cut such distal portion from a cuneiform (e.g., medial cuneiform 20).

After a desired angle of stem 630 (e.g., axis 632 thereof) relative to axis 34 of second metatarsal 36 is determined (e.g., by a surgeon examining such angle), and an amount of the cuneiform (e.g., medial cuneiform 20) to be removed is determined, and axis 632 is aligned relative to axis 34 as desired, a K-wire 2410 may be inserted through proximal locking hole 625 to secure guide 100 in a desired position. Locking hole 625 may have an axis aligned at a non-perpendicular angle relative to the longitudinal dimension of stem 630 as depicted in FIGS. 10 and 14. For example, a top end of the K-wire 2410 received in locking hole 625 may be located further than a bottom end thereof from distal locking hole 660 at an opposite end of cut guide 600 such that the top portion is angled proximally to securely fasten cut guide 600 relative to first metatarsal 30. After cut guide 600 is attached to foot 10, a saw (e.g., saw 170) may be utilized to cut the cuneiform (e.g., medial cuneiform 20) via second proximal slot 654 of cut guide 100 as depicted in FIG. 14.

Saw blade 170 may be removed from cut guide 600 as depicted in FIG. 15 and a K-wire (e.g., K-wire 2410) may be removed from the cut guide (e.g., from proximal locking hole 125) as depicted in FIG. 16. Cut guide 600 may be removed from the remaining K-wire (e.g., K-wire 2400) as depicted in FIG. 17.

After the cleaning up of the first metatarsal (i.e., first metatarsal 30), i.e., resecting a portion thereof, as described above and cutting the cuneiform (i.e., cuneiform 20) at a desired angle as described above, a space or an aperture 40 (FIGS. 18 and 19) between the bones (e.g., bone portions of foot 10) created by the cutting allows the metatarsal to be manipulated into place (i.e., due to the presence of aperture 40) so that the two cut surfaces (i.e., a distal surface of the cuneiform and proximal surface of the metatarsal) are aligned as depicted in FIGS. 20-21. FIG. 19, which is a blow up of a portion of FIG. 18, depicts a pre-manipulated arrangement of foot 10, including aperture 40. Also, FIGS. 22-23 depict foot 10 prior to the correction described above, while FIGS. 24 and 25 depict foot 10 after such correction.

FIGS. 32-33 depict a reverse side of cut guide 600 with top and bottom sides reversed. such that cut guide may appear identical to cut guide 600 except that stem 630 and a hole 610 bounded by stem extension 612 may be offset toward a right side of a center of a transverse dimension of cut guide 600 relative to an axis of stem 630 instead of being offset toward a left side thereof. Also, a second distal locking hole 674 of holes 670 may now have an axis angled such that a top end thereof is further from stem extension 612 than a bottom end thereof. A second hole 611 may also be utilized instead of or in addition to hole 610 to receive a K-wire to attach cutting guide 600 to a bone (e.g., foot 10). For example, hole 610 and second hole 611 may have axes oriented proximally and distally opposite to one another such that K-wires received therein may include top and bottom ends located distally and proximally opposite one another relative to anchor portion 602 and/or second distal locking hole 674.

In an example, a cut guide 300 is depicted in FIG. 26. In contrast to cut guide 600, cut guide 300 may include a plurality of adjustment holes 320 extending vertically through an anchoring portion 355 of cut guide 300 and configured to receive a K-wire (e.g., K-wire 2400). Cut guide 300 may be placed over K-wire 2400 via a middle opening or hole 310 of adjustment holes 320. A stem 330 of cut guide 300 is connected to a cut body 340 having a first proximal cut slot 345 and a second distal cut slot 350 having longitudinal dimensions extending about or approximately perpendicular to a longitudinal dimension of stem 330.

Cut guide 300 may be located relative to a bone (e.g., foot 10) similarly to cut guide 600 such that a longitudinal dimension or axis thereof is aligned with or extending parallel to axis 32 of first metatarsal 30.

Stem 330 and anchoring portion 335 may extend from a medial-lateral middle portion of a body 340 such the cut guide is symmetric in an axial direction relative to stem 330 and may be utilized as a universal left and right design. More specifically, the symmetric nature of stem 330 and anchoring portion 335 allow cut guide 330 to be flipped over but a longitudinal axis of stem 330 remains centrally located and aligned relative to a central axis of cut guide 300 and about perpendicular to longitudinal dimensions of slots (slot 345 and slot 350) of cut guide 300.

As depicted in FIG. 27, a cut guide 100 includes a stem 130 and an anchoring portion 200, which similar to stem 330 and anchoring portion 335, are aligned with each other and offset from a center axis thereof such that different right and left cut guides may be utilized. For example, stem 130 and anchoring portion 200 are offset left of a longitudinal axis of cut guide 100 and a complementary cut guide (not shown) would be offset right of such longitudinal axis. In another example depicted in FIGS. 28-29, a cut guide 500 includes a symmetric universal left and right design where the left cut guide is on the top and right cut guide is on the bottom such that the cut guide may be flipped over from one side to the other depending on the cut desired. Further, cut guide 500 may include a single slot 540 and cut guide may be manipulated such that K-wire 2400 is located among various adjustment holes 520 to longitudinally locate cut guide 500 and slot 540 to allow cuts to be made at various longitudinal locations.

As described above, a cut guide (e.g., cut guide 100, cut guide 300 and cut guide 500) may include several adjustment holes (e.g., holes 320) for receiving K-wires (or other attaching members) to allow the cut guide to be temporarily located or fixed at desired locations (e.g., longitudinal locations along an axis of a metatarsal or desired axis of a rearranged metatarsal) to allow cutting, marking and aligning of metatarsal, phalanges, cuneiform or other portions of a foot. For example, a drilling guide (e.g., guide 2000) and a cut guide (e.g., cut guide 100, cut guide 300, guide 500 and cut guide 600) described above may be utilized to perform a Lapidus procedure. In other examples of cut guides (e.g., cut guide 600), a single anchoring hole (e.g., anchoring hole 610) may be utilized to hold a cut guide relative to a bone (e.g., foot 10) and multiple slots (e.g., slots 650) may be utilized to cut portions of the bone at various increments and at various angles to remove portions thereof to provide a cavity or aperture (e.g., aperture 40) to allow a repositioning of bone portions (e.g., cuneiform 20 and first metatarsal 30).

As described above, a cut guide (e.g., cut guide 100, cut guide 300, cut guide 500, cut guide 600) may include a stem portion (e.g., stem 130, stem 330, stem 530, stem 630) that may be aligned with a desired final alignment of a bone (e.g., a metatarsal) to be manipulated into a final position (e.g., relative to a cuneiform, phalange and/or a remainder of a foot) after the bone and/or an adjacent bone is cut. The cut guide may be aligned with such desired final alignment and secured via a K-wire to the foot such that slots of the cutting guide may be utilized to make cuts (e.g., perpendicularly relative to the desired final alignment) of the bone to allow such desired final alignment to be achieved. The slots (e.g., slot 145, slot 150 of cut guide 100, slots 650 of cut guide 600) may be aligned with longitudinal dimensions substantially perpendicular to the axis (e.g., axis 132) of the cut guide or such slots may be aligned at other desired angles relative to the axis and/or each other as desired relative to cuts to be performed for particular corrective procedures (e.g., the Lapidus procedure).

While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
