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 shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.
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.
A patient-specific instrument is disclosed for performing an osteotomy. The patient-specific instrument includes a body that includes a proximal side, a distal side, a medial side, a lateral side, and an inferior side having a bone engagement surface shaped to match at least one of a first surface of a first bone, a second surface of a second bone, a third surface of a third bone, and a fourth surface of a fourth bone of adjacent joints. The instrument also includes a superior side having one or more guide features that are positioned to guide resection of at least one of the first bone, the second bone, the third bone, and the fourth bone.

The multi-diameter fixation pin may include a trailing diameter different than the leading diameter. The trailing diameter may be sized for use with a specific sized powered driver. For example, in orthopedic procedures that involve inserting larger diameter pins and smaller diameter pins into bone(s), all pins used in the procedure may have a trailing diameter (e.g., the larger diameter or the smaller diameter) that allows the pins to be inserted with the same powered driver (e.g., the same attachment head) without needing different sized drivers or attachment heads for different sized pins.
Instruments and surgical techniques may be used to correct a bone deformity, such as a bunion in which a metatarsal is misaligned with respect to a medial cuneiform. In some examples, a bone cutting guide is utilized to cut an end of the metatarsal and/or an end of the medial cuneiform to facilitate realignment of the bones. The cutting guide can have a pivotable cut guide surface along which a cutting instrument is translated to provide a precise bone cut. In some applications, after suitably preparing and aligning the bones, the bones are compressed together using a fixation pin. The fixation pin can be driven through one of the bones, into the second bone, and then further driven to compress the bones together.

A bone plate can be used to fixate one or more bones. In some examples, a bone plate has first, second, third, and fourth fixation holes. The first and second fixation holes may be located in a distal body region of the bone plate and co-linear with a bridge central longitudinal axis. The third and fourth fixation holes may be located in a proximal body- region of the bone plate, with the third fixation hole co-linear with the bridge central longitudinal axis and the fourth fixation hole offset from the bridge central longitudinal axis in a first plane by a first angle and in a second plane by a second angle.
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.
An orthopedic cutting instrument can be used to cut and release soft tissue to mobilize a bone for subsequent realignment of the bone. In some examples, the cutting instrument is configured with a handle and a cutting head. The cutting head has multiple cutting surfaces, such as a lead cutting surface and side cutting surfaces extending angularly away from the lead cutting surface. A mirror set of cutting surfaces may be provided on the opposite side of the cutting head. The cutting surfaces may be arranged to allow controlling cutting of soft tissue while limiting inadvertent deep penetration of the cutting instrument. In addition, the cutting surfaces may be arranged to allow back-and-forth cutting movement of the cutting head, which can be useful when working in a tight joint space.
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.

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.

METATARSOPHALANGEAL JOINT PREPARATION AND METATARSAL REALIGNMENT FOR FUSION
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.
