A saw blade for use in an orthopedic procedure may have multiple regions of different thickness across the length of the saw blade. The saw blade may include at least one region that is comparatively thicker. The saw blade may also include at least one region that is comparatively thinner and position closer to an end of the saw blade having cutting teeth. In some configurations, the thicker region of the saw blade is an intermediate region located between two comparatively thinner regions. The intermediate thicker region can interface with a slot of a cutting guide while the comparatively thinner regions can be sides for engaging with a driver and controlling the kerf width of a bone cut made using the saw blade, respectively.

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.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

A bone positioning guide may be used as part of a bunion correction procedure. The bone positioning guide can include a bone engagement member configured to be positioned on a medial side of a first metatarsal of a foot and a tip separated from the bone engagement member by a distance effective to position the tip on a lateral side of a second metatarsal and in an intermetatarsal space between the second metatarsal and a third metatarsal. The bone positioning guide can also include a mechanism operable to reduce the distance between the bone engagement member and the tip, thereby causing the first metatarsal to move in at least a transverse plane to reduce an intermetatarsal angle between the first metatarsal and the second metatarsal.

Disclosed are bone screw drill targeting guides and methods for using such targeting guides that are useful in surgical procedures for correcting hallux valgus deformity.

An alignment device includes a first member, a second member, and a guide. The first member has an elongated body and is configured to be at least partially inserted into a canal in a first bone portion. The second member includes a body attachable to the first member and an arm extending from the body. The arm defines a track. The guide is configured to translate along the track defined by the arm. The guide includes an aperture configured to receive an alignment member therethrough. The guide is configured to be positioned at a desired position along the track to allow insertion of the at least one alignment member through the aperture and into the first bone portion at a desired trajectory.

An orthopedic implant is specifically configured for use in osteotomies, in which part of the implant extends into an intramedullary portion of a first bone segment and a plate portion is external to the cortical surface of an adjacent bone segment to fix the segments to allow them to fuse. The body of the implant has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the implant, and which can receive a screw, peg or pin. The second end of the implant includes a plate portion with at least two offset screws.

A cutting guide includes a body and a rotatable device. The body includes a top portion, a bottom portion parallel to the top portion, and a side portion connecting the top and the bottom portions. The rotatable device is coupled to one end of the top portion of the body, and includes a pivotal element and a handle. The handle in the rotatable device has a first portion coupled to the pivotal element, and a second portion configured to be rotated around an axis of the pivotal element. Each of the top portion of the body, the side portion of the body, the bottom portion of the body, and the handle has one respective edge providing a respective guide surface for cutting a bone in a surgical procedure.

An ankle arthroplasty system may have a talar prosthesis and a tibial prosthesis, each of which has an articular surface and a bone engagement surface. Each bone engagement surface may have an anterior-posterior curvature and a medial-lateral curvature with a convex shape. A burr with a rotatable cutting element may be used to form a prepared surface on the talus or the tibia to receive the corresponding prosthesis. A cutting guide may be used to guide motion of the burr; the cutting guide may include a base and an arm movably coupled to the base. One of the base and the arm may have a guide surface, and the other may have a follower that slides along the guide surface to constrain motion of the burr such that the prepared surface has at least one concave curvature and one convex curvature.

A compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the compressor-distractor includes first and second engagement arms having first and second pin-receiving holes, respectively. The first and second pin-receiving holes may be angled relative to each other. The compressor-distractor may also include an actuator operatively coupled to the first and second engagement arms. In some example uses, a clinician may pin a first surgical device to a patient's bones use a pair of parallel pins. After removing the surgical device over the parallel pins, the clinician may thread the parallel pins through the angled first and second pin-receiving holes of the compressor-distractor, causing the bones to move relative to each other. Thereafter, the clinician may actuate the actuator on the compressor-distractor to move the bones towards and/or away from each other.
