Disclosed are bone screw drill targeting guides and methods for using such targeting guides that are useful in surgical procedures for correcting hallux valgus deformity.

In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

A surgical technique can involve inserting an instrument defining a sliding surface between a metatarsal and a laterally-adjacent metatarsal. The technique can include moving the metatarsal across the sliding surface of the instrument toward the cuneiform to close a space between the metatarsal and the opposed cuneiform.

Guides, systems, and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The guide system including a cut guide, an alignment guide, and at least one directional wire. The cut guide including a base portion, an extension member extending away from a bottom surface of the base portion, and at least one arm extending away from an end of the base portion. The alignment guide, including a base portion, a first extension member extending away from a bottom surface of the base portion in a first direction, and a second extension member extending away from the bottom surface of the base portion in a second direction. Methods of using a guide system for maintaining, correcting and/or fusing joint deformities are also disclosed.

A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument. The technique may include preparing an end of a first metatarsal and preparing an end of a medial cuneiform opposing the end of the first metatarsal. The technique may also include moving the first metatarsal relative to the medial cuneiform. The technique can involve inserting the instrument between a first metatarsal and a second metatarsal.

A minimally invasive method of correcting a bunion includes performing an osteotomy to divide the metatarsal into first and second portions, creating a pocket in the first portion implanting a nail in the pocket, securing a suture to the joint capsule, tensioning the suture to align the great toe with the metatarsal, attaching the suture to the nail, and fastening the nail to the second portion. The nail includes an anchor portion for anchoring in the first portion, a head for attachment to a second portion, a passage for attachment of the suture, a first aperture for a fastener to attach the head with the first portion, and a second aperture for a fastener to attach the head with the second portion.

Osteotomy cutting systems and surgical methods are provided herein. One surgical method includes coupling, to a cuneiform of a subject, a surgical apparatus for use in facilitating correction of a bunion and coupling the surgical apparatus to another bone of the subject. Another surgical method includes coupling a surgical apparatus to a cuneiform and metatarsal of a subject, coupling a cutting block for alignment at a joint between the cuneiform and the metatarsal, and performing a surgical procedure utilizing the surgical apparatus and the cutting block to correct a bunion. A further surgical method includes providing a surgical apparatus for use in facilitating correction of a bunion in a subject in which the surgical apparatus is configured to couple to a cuneiform and a metatarsal of the subject and performing a surgical procedure utilizing the surgical apparatus while the surgical apparatus is coupled to the cuneiform and the metatarsal.
