A new and innovative method of routing a strand of material for creating a self-locking construct that joins two objects is provided. More specifically, the provided routing method includes a crossover point at which the routed strand of material crosses over itself thereby enabling the strand portions routed through one of the objects to travel in a same direction when the self-locking construct is cinched. The strand portions traveling in the same direction generates less friction between the portions than if the portions traveled in opposite directions. Accordingly, the provided routing method helps enable a self-locking construct that generates less friction than typical self-locking constructs, which thereby helps reduce the occurrences of weaknesses in the final self-locking construct. The reduced friction generation also helps increase an ease of use for a user when cinching the self-locking construct.

A button inserter and system are disclosed that enable easily and effectively deploying a near bone suture button from the button inserter when implementing the suture button technique. To deploy the near bone button, with a far bone button deployed from the button inserter and against the far bone, the button inserter's handle may be translated away from the deployed far bone button. Translating the handle changes a position of a carriage body within a channel of the handle thereby compressing a spring. Protrusions on the carriage body may be forced through notches in the handle, which thereby alters an orientation of the carriage and releases the compressed spring, which applies force to the carriage body. The combination of force induces the carriage to rotate, which thereby releases the near bone button from the carriage. A free end of suture also releases from the carriage.

A new and innovative medical sizing instrument and method are provided for determining an appropriate depth and/or length of a clavicle hook plate for a patient. The provided medical sizing instrument may enable a surgeon to determine an appropriate hook depth without having to switch between different components, such as a series of templates. In an example, a surgeon may insert the medical sizing instrument into a patient the same as the surgeon would a clavicle hook plate, adjust the hook depth on the medical sizing instrument until a hook depth is obtained that appropriately maintains the anatomical alignment of the patient's clavicle and acromion, and read an indicated depth on the medical sizing instrument. The surgeon may then remove the medical sizing instrument from the patient and select the appropriate clavicle hook plate to insert into the patient.

Suture buttons are disclosed for fixing two bones together. The suture buttons may enable surgeons to more easily and effectively implement a suture button technique, such as to repair syndesmosis injuries in ankles. A first suture button includes a pulley peg extending from a button head. The pulley peg may be positioned with a bone hole upon installation of the first suture button, which may help protect suture and help reduce potential patient discomfort. The second suture button helps facilitate the second suture button flipping into place upon deployment from a button inserter. Each of the first and second provided suture buttons may help reduce friction between the respective buttons and suture during an installation procedure. The first and second provided suture buttons may be used together in a surgical procedure or individually with other suitable buttons or anchors.

Orthopedic guide, and methods of using the guide, for alignment of bone under fluoroscopic imaging. In an exemplary embodiment, the guide may include a radiopaque rod, a radiolucent carrier, and a radiopaque indicator held by the carrier. The rod and the indicator may be parallel to the same plane, and may form an angle between one another of less than 90 degrees when projected orthogonally onto the plane. The rod may be configured to be aligned with an axis defined by one or more bones of the leg, and the indicator aligned with a joint of the leg, in an anterior-posterior, fluoroscopic view of the leg. The angle formed between the rod and the indicator may correspond to an anatomic orientation of the axis and the joint relative to one another in a frontal plane of the leg.

Apparatus and methods for distracting and/or compressing bone. An exemplary apparatus may comprise a rod having a thread. The apparatus also may comprise a first assembly and a second assembly each coupled, or configured to be coupled, to the rod and each configured to be attached to a respective pin extending into bone. The apparatus further may comprise a nut engaged, or configured to be engaged, with the thread and configured to be turned to drive the second assembly along the rod. In some embodiments, at least one of the assemblies may have at least two degrees of rotational freedom that can be eliminated by manipulating a single graspable member. In some embodiments, the rod and the second assembly may have anti-rotation features configured to interact with one another to permit travel of the second assembly along the rod while preventing rotation of the second assembly about the rod.

Distraction/compression apparatus and method for bone

Bone fixation system, including methods, apparatus, and kits, and comprising a bone plate and at least one instrument that attaches to the bone plate and provides at least one radiopaque region to facilitate positioning the bone plate on bone visualized by radiographic imaging. The instrument may be a handle assembly and/or a targeting guide.

System, including methods and apparatus, for deforming a plate member on bone. In some embodiments, the system may comprise a plate member defining a plurality of openings to receive fasteners that attach the plate member to bone. The plate member may include a pair of undercut flanges formed by opposite edge regions of the plate member. The system also may comprise a bending tool configured to be operatively associated with the plate member after the plate member is attached to bone, with a region of the bending tool positioned under each of the undercut flanges, such that rotation of the bending tool applies a moment to the plate member.

System for deforming plate members on bone

System, including apparatus and methods, for fixing bone with a bone plate supported temporarily at a slant on bone by a leg member before the bone plate is used as a lever to reposition a region of the bone. In some embodiments, the leg member may be a post member that attaches to the bone plate by threaded engagement with an aperture of the bone plate. In some embodiments, the bone plate and the leg member may be used near the end of a long bone, such as on a distal portion of a radial bone.
