Abstract: A reversible compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the reversible compressor-distractor is configured to be interchangeably used on right and left feet by reversing the orientation of the compressor-distractor. For example, the compressor-distractor may include a first engagement arm having at least two oppositely orientated pin-receiving holes on different sides of the engagement arm. The compressor-distractor may also include a second engagement arm having at least one pin-receiving hole. In use, the clinician can select an orientation of the compressor-distractor and engage pin-receiving holes associated with the selected orientation.

Abstract: An orthopedic implant system can be used to fixate two bones (e.g., to portions of a single bone) relative to each other during a surgical procedure. In some configurations, the implant system includes a staple having at least two legs separated by a bridge. The staple can include at least two couplings on either side of the bridge accessible through a top surface of the staple connectable to two corresponding coupling shafts. The coupling shafts can attach through the top surface of the staple without extending below an underside of the staple. The coupling shafts can be used to bias the at least two legs of the staple away from each other for insertion into holes formed into two bones. By attaching the coupling shafts through the top of the staple, the staple can be inserted flush with the two bones before releasing the shafts.

Abstract: Systems, techniques, and devices are described that may be used in a minimally invasive bone realignment procedure. In some examples, a method of performing a minimally invasive metatarsal correction procedure involves using a bone preparation guide having a guide surface with a length less than a diameter of a bone to be cut using the guide surface. The clinician can guide a bone preparation instrument along the guide surface and angle the bone preparation instrument beyond one or both ends of the guide surface to cut the end of the underlying bone beyond one or both of the ends.

Abstract: An orthopedic implant system can be used to fixate two vertebral bones relative to each other during a surgical procedure. In some configurations, the implant system includes a staple having at least two legs separated by a bridge. The staple can include at least two couplings on either side of the bridge accessible through a top surface of the staple connectable to two corresponding coupling shafts.

Abstract: 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.

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. 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.

Abstract: 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.

Abstract: 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.
