Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Systems, devices, and techniques can be used to perform an osteotomy on a bone of a foot, to realign a cut bone portion relative to an adjacent bone portion, and/or to fixate a moved position of the cut bone portion relative to the adjacent bone portion for fusion. In some examples, the disclosed devices and techniques can be used as part of a metatarsal correction procedure in which a metatarsal is treated to correct a bunion deformity.

Abstract: 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 and making it less invasive. For example, one or more cut guides having tissue control features may be utilized during procedure.

Abstract: 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.

Abstract: A method of placing an implant at one or more bone portions includes inserting a pinning and drilling instrument a first distance into a bone portion at a location at the bone portion such that a pin portion of the pinning and drilling instrument is inserted into the bone portion at the location; after inserting the pinning and drilling instrument the first distance into the bone portion, creating an implant receiving aperture at the location by further inserting the pinning and drilling instrument a second further distance into the bone portion at the location at the bone portion such that a drill portion of the pinning and drilling instrument is inserted into the bone portion to create the implant receiving aperture at the location; and placing an implant at the implant receiving aperture.

Abstract: A method of fixating bones for fusion includes positioning an implant guide sleeve at a first bone and a second bone and across a separation between the first bone from the second bone. The method further includes using the implant guide sleeve to guide creation of a first implant hole in the first bone and to guide creation of a second implant hole in the second bone, aligning an inserter, operatively connected to an implant, with the implant guide sleeve, and advancing the inserter, relative to the implant guide sleeve, to position the implant in contact with the first bone and the second bone with the implant bridging between the first bone and the second bone.

Abstract: A method of modifying a bone surface for receiving an implant includes: positioning a contour guide at a first bone and a second bone and across a separation between the first bone and the second bone; using the contour guide to modify a surface region of at least one of the first bone and the second bone to form a modified surface region at one or both of the first bone and the second bone; and positioning an implant in contact at least with the modified surface region.
