Instruments and techniques can be used to release a first metatarsal for realignment. In some implementations, a techniques involves surgically accessing a sesamoidal ligament in a foot of a patient and advancing a guiding projection of a cutting instrument under the sesamoidal ligament. This can capture the sesamoidal ligament between the guiding projection of the cutting instrument and a cutting surface of the cutting instrument that is recessed relative to a distal end of the guiding projection. The techniques further involves cutting the sesamoidal ligament with the cutting surface of the cutting instrument.

First metatarsal lateral release instrument and technique

A variety of surgical procedures may be performed on the bones of the foot, such as on one or more lesser metatarsals of the foot positioned laterally of the first metatarsal. For example, a surgical procedure may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform and/or cutting an end of one or both of a third metatarsal and a lateral cuneiform. The tarsometatarsal joints defined be one or both sets of bones may be cut to treat an arthritic joint, metatarsus adductus, and/or other clinical condition. In any case, various surgical instruments can be utilized during a procedure to help increase the accuracy and repeatability of the procedure patient-to-patient, improving overall patient outcomes. For example, one or more cut guides, compressor-distractor devices, and/or other instruments designed to accommodate the specific anatomical conditions of the procedure being performed may be utilized during procedure.

Devices and techniques for treating lesser metatarsals of the foot

A metatarsus adductus technique may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform to create a wedge-shaped opening between the end of the second metatarsal and the intermediate cuneiform. The method may further involve cutting an end of one or both of a third metatarsal and a lateral cuneiform to also create a wedge-shaped opening between the end of the third metatarsal and the lateral cuneiform. The second metatarsal and the third metatarsal can then be moved in a transverse plane to close a metatarsus adductus angle. Movement of the second and third metatarsal may close the wedge-shaped openings forming during bone cutting. With the second and third metatarsals appropriately realigned, the clinician can fixate the moved position of the second metatarsal and the third metatarsal.

Orthopedic retractor

A method of preparing a metatarsophalangeal joint for fusion may involve surgically accessing the metatarsophalangeal joint and separating the metatarsal from the opposed proximal phalanx at the joint. The technique may involve preparing an end of the metatarsal and preparing an end of the opposed proximal phalanx for fusion. With or without the aid of a bone positioner, the metatarsal may be moved in one or more planes, such as the frontal and transverse planes. The proximal phalanx may also be moved in one or more planes, for example relative to the moved metatarsal. Subsequently, a bone fixation device can be applied across or through the metatarsophalangeal joint separating the metatarsal from the opposed proximal phalanx.

Metatarsophalangeal joint preparation and metatarsal realignment for fusion

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

Metatarsal cut guide with parallel cut faces

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.

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.

Tarsal-metatarsal joint procedure utilizing fulcrum

A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument that defines a spacer body connected to a fulcrum. The spacer body portion of the instrument can be inserted into a joint space between opposed bone ends. The fulcrum body can be inserted between adjacent metatarsals. An angle set between the spacer body and fulcrum body can help properly position both features within different joint spaces for ensuring that subsequent steps of the surgical procedure are properly performed and instrumentation is appropriately aligned.

Bi-planar instrument for bone cutting and joint realignment procedure

A bone cutting and joint realignment instrument may include an integrated spacer body, bone preparation guide, and fulcrum body. The spacer body is configured to be inserted into a joint space between a metatarsal and an opposed cuneiform of a foot. The bone preparation guide body is affixed to the spacer body with the spacer body extending downwardly from the bone preparation guide body. The bone preparation guide body can define at least one guide surface configured to be positioned over at least one of the metatarsal and the opposed cuneiform. The fulcrum body may be rotatably coupled to the spacer body within a bounded range of rotation, such as a bounded range of less than 45 degree. The fulcrum body can be configured to be inserted in an intermetatarsal space between the metatarsal and an adjacent metatarsal.

Cut guide with integrated joint realignment features

Lesser metatarsal cut guide with parallel cut faces

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.
