At step702, a cut is formed in a metatarsal at a surgical site800. As shown inFIG.15A, a foot802comprises a plurality of bones, including a first toe804having a plurality of phalanges806a-806b, a metatarsus808, and a plurality of cuneiforms810. A portion of the metatarsal808is removed during the initial cut. In some embodiments, one or more continuous and/or non-continuous cuts are made to form a chevron-shaped osteotomy. For example, in some embodiments, rotation of the burr812about a point of entry into the patient's anatomy is used to form a dorsal limb and a plantar limb of a chevron osteotomy. The plane of the osteotomy is defined by the entry cut of the burr812into the metatarsal808. The burr812may be left in a final position to act as a guide for one or more additional surgical elements.

At step704, a portion of the metatarsal, such as the metatarsal head, is displaced from an initial position, as shown inFIG.15B. In some embodiments, the displacement of the metatarsal head is achieved by a displacement elevator302as shown and described herein. As shown inFIGS.16A-16B, a displacement tip306of an elevator302can be positioned near a metatarsal808to displace a portion of the metatarsal. The body304of the elevator302is rotated such that the displacement tip306displaces a first portion810from a second portion of the metatarsus808to form an osteotomy.

As shown inFIGS.14B-14D, one or more k-wires are inserted into the patient, for example, into the metatarsus808through the k-wire guide holes112. The k-wire guide holes112guide the k-wires125to a predetermined implantation position within the patient's toe. For example, in some embodiments, the k-wires125are implanted through the guide holes112to one or more positions corresponding to a chevron osteotomy.

At step708, after the k-wires125are implanted, the targeting guide102can be removed from the surgical site802. The k-wires125can be inserted from a dorsal (proximal fragment) to planter (head fragment), for example, utilizing a long tail/plantar limb of the chevron and/or can be inserted from a dorsomedial (proximal fragment) to planter lateral (head fragment). In some embodiments, a k-wire125is inserted through one or more cortices of the proximal fragment prior to entry into the metaphysis of the head fragment. In some embodiments, the burr812is removed from the metatarsal and the targeting guide102is slidably removed over the k-wires125. In some embodiments, a cut is made in the metatarsus808to facilitate removal of the targeting guide102and burr812. The cut may be formed by, for example, the burr812and/or any other suitable cutting instrument.

At step710, the osteotomy is fixed using one or more fixation devices820. For example, in some embodiments, one or more screws may be inserted through a first portion808into a second portion810to fix the osteotomy. In some embodiments, the fixation devices include cannulated screws inserted from the second portion808to a first portion810of the metatarsus808. In other embodiments, one or more additional percutaneous k-wires125are inserted to permanently fix the osteotomy.

In some embodiments, insertion of one or more fixation devices820is facilitated by a surgical guide, such as the surgical guides600a,600bdescribed above. In some embodiments, the surgical guide600a,600bis coupled to a k-wire125previously inserted at a surgical site800. The k-wire125can be coupled to the surgical guide600a,600bby sliding the k-wire125through one or more holes and/or slots defined by the surgical guide600a,600b. For example, in some embodiments, the surgical guide600ais positioned by sliding a k-wire125through a first hole610defined by a first arm608and a slot614defined by an alignment body612.

One or more fasteners680a,680bcan be inserted through one or more fastener holes626a,626b674a,674bdefined in a portion of the surgical guide600a,600b. For example, in some embodiments, a first fastener680aand a second fastener680bare inserted through first and second fastener holes626a,626bformed in a second arm620of the surgical guide600a. A first fastener680acan be inserted at an angle with respect to a second fastener680b(as shown inFIG.15F) and/or can be inserted parallel to the second fastener680b(as shown inFIG.15G). The fasteners680a,680bmaintain the osteotomy in a fixed position during bone healing.

In some embodiments, the first hole defined by the first arm aligns with the second slot defined by the alignment body. The alignment body can be configured to move along the length of the first slot defined by the body and to move transversely relative to a longitudinal axis defined by the first slot.

In some embodiments, the second arm defines a pair of parallel holes adjacent to an end thereof. The first arm can extend perpendicularly from the central section and the second arm can extend from the central section at an angle between zero and ninety degrees.

In some embodiments, the first slot extends through a first side and a second side of the central section. The central section can define a second slot that extends through a third side and a fourth side of the central section of the body. The first hole can extend through the first arm in a direction that is perpendicular to a longitudinal direction of the central section.

In some embodiments, the alignment body defines a second hole that extends through the alignment body in a first direction and defines a third hole that extends through the alignment body in a second direction. The first direction can be parallel to the second direction.

In some embodiments, the alignment body is configured pivot about and axis that is oriented perpendicularly with respect to a longitudinal direction of the central section.

In some embodiments, the first arm is configured to rotate about a longitudinal axis defined by the central section of the body and is configured to slide in directions that are perpendicular to a longitudinal axis defined by the central section of the body.

In various embodiments is disclosed. The method includes inserting a guide wire into a shaft of a metatarsal without inserting the guide wire into a head of the metatarsal, coupling an alignment guide to the guide wire, displacing the head of the metatarsal using the alignment guide, inserting a first screw into a first hole defined by the alignment guide, and inserting a second screw into a second hole defined by the alignment guide. The first hole can define a first axis that is parallel to a second axis defined by the second hole.

In some embodiments, the first and second holes are defined by an arm extending from a central section of the alignment guide. The first and second holes can be defined by an alignment body that is slidably received within a slot defined by a central section of the alignment guide.

In various embodiments, a method is disclosed. The method includes inserting a guide wire in a medial-to-lateral direction through a first head of a first metatarsal and into a second head of a second metatarsal, coupling an alignment guide to the guide wire, inserting a first screw into a first hole defined by the alignment guide, and inserting a second screw into a second hole defined by the alignment guide. The first hole can define a first axis that is parallel to a second axis defined by the second hole.

In some embodiments, the first and second holes are defined by an arm extending from a central section of the alignment guide. In some embodiments, the first and second holes are defined by an alignment body that is slidably received within a slot defined by a central section of the alignment guide.

Although the subject matter has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments, which may be made by those skilled in the art.
