A technique for correcting a bone deformity, such as a bunion, may be performed using a fulcrum. In some examples, the fulcrum includes multiple members that are joined together at one end and spaced apart from each other at an opposite end. The fulcrum members can be manipulated to adjust the distance separating the fulcrum members from each other and, correspondingly, an amount of force separating the multiple members from each other. The force can be controlled to press against opposed bones, such as first and second metatarsals in an intermetatarsal space.

Fulcrum for tarsal-metatarsal joint procedure

In some examples, a method for preparing one or more bones involves inserting a spacer into a space defined between a first bone and a second bone, such as a joint space between a first metatarsal and medial cuneiform. A bone preparation guide can be aligned with opposed ends of the first bone and the second bone using the spacer as an alignment reference. For example, the bone preparation guide may include an opening such that the guide can be installed across the joint space with the spacer received in the opening. A clinician may use the bone preparation guide to guide a tissue removing instrument to cut or otherwise prepare the ends of the first bone portion and second bone portion.

Joint spacer systems and methods

A metatarsal correction procedure may be performed so as to minimize the length of the surgical incision created during the procedure. A variety of different instruments and/or techniques and facilitate the minimal incision procedure. In some examples, a technique involves making a comparatively small surgical incision to access a tarsometatarsal joint. A metatarsal and a cuneiform separated by the tarsometatarsal joint can be prepared. In addition, the metatarsal can be moved relative to the cuneiform using a bone positioning device having a metatarsal engagement member positioned in contact with the skin of the patient on a medial side of the metatarsal. After moving the metatarsal, a fixation device can be installed across the tarsometatarsal joint to cause fusion. In some examples, a plate holder is attached to a U-shaped bone plate to facilitate plating across the joint through the comparatively small incision.

System and technique for metatarsal realignment with reduced incision length

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.

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

Bone positioning and preparing guide systems and methods

A bone cutting guide may include a support that contains a shaft movable relative to the support. The shaft may carry a guide member having one or more cut guides through which a clinician inserts a cutting member to cut bone positioned under the guide cut guides. In operation, a clinician may fixate the support of the bone cutting guide to a bone and translate the guide member until the one or more cut guides are positioned at a desired cut location. The clinician may then perform a cut through the cut guide. In some examples, the bone cutting guide includes additional components, such as bridging member or secondary cut guide, to provide additional functionality.

Bone cutting guide systems and methods

A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument. In some examples, the technique involves inserting the instrument between a first metatarsal and a second metatarsal. The technique further includes preparing an end of the first metatarsal and preparing an end of a medial cuneiform opposing the end of the first metatarsal.

A bone harvester and bone marrow removal system. The bone harvester can include a body defining a channel extending longitudinally therethrough from a distal to a proximal portion of the body. The distal portion can include a cutting tip. Bone marrow may be drawn through the channel.

Bone harvester and bone marrow removal system and method

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.

Bone positioning guide

An osteotomy procedure may be performed to correct a misalignment of a bone, such as a bunion deformity. In some examples, the osteotomy procedure involves making a spherical-shaped cut transecting a first metatarsal, thereby forming a first metatarsal portion having a spherical-shaped projection and a second metatarsal portion having a spherical-shaped recess. The method further involves moving the second metatarsal portion in at least two planes relative to the first metatarsal portion, thereby adjusting an anatomical alignment of the second metatarsal portion.

Osteotomy procedure for correcting bone misalignment

A pin lock may be used to prevent a compressor-distractor from pushing off of a surgical pin as the compressor-distractor is actuated to move one bone relative to another bone. In some examples, the compressor-distractor is attached to a metatarsal with a first pin and to a cuneiform with a second pin. The pin lock can be inserted onto the first pin or the second pin, optionally with a second pin lock inserted onto the other pin. The compressor-distractor can then be actuated while the compressor-distractor is locked by the pin lock from moving up along the axial length of the first pin or the second pin.

Surgical pin positioning lock

A method of correcting an alignment between bones of a foot may involve positioning a first cutting slot of a bone cutting guide over a first metatarsal and inserting a first fixation pin through a first fixation aperture of the bone cutting guide and into the first metatarsal. The method may also involve inserting a cutting member through the first cutting slot to remove a portion of the first metatarsal and adjusting an alignment of the first metatarsal relative to a first cuneiform. In some examples, the method further includes positioning a second cutting slot of the bone cutting guide over the first cuneiform and inserting a second fixation pin through a second fixation aperture of bone cutting guide into the first cuneiform. The method can involve inserting a cutting member through the second cutting slot to remove a portion of the first cuneiform and causing the first metatarsal to fuse to the first cuneiform in the moved position.

A method of preparing a tarsometatarsal joint can include imaging a tarsometatarsal joint of a patient between a metatarsal and a cuneiform to determine a size and/or angle of a wedge-shaped bone portion to be cut at the tarsometatarsal joint. The method can include obtaining a bone preparation guide that includes a first guide surface positionable over the metatarsal and a second guide surface positionable over the cuneiform, where an angle of the first guide surface relative to the second guide surface is selected corresponding to the size and/or angle of the wedge-shaped bone portion to be cut as determined via imaging of the tarsometatarsal joint. The method can include positioning the guide surfaces over the metatarsal and cuneiform and guiding a tissue removing instrument with the guide surfaces to cut an end of the metatarsal and to cut an end of the cuneiform.
