Abstract: An intramedullary (“IM”) nail and surgical technique or method. The IM nail includes a body including an opening for receiving a lag screw and a compression screw. The body further including one or more screw openings for receiving a bone screw. The surgical technique enables a surgeon to selectively prevent or allow movement (e.g., medialization) of the IM nail within the patient's intramedullary canal. The position of the IM nail can be selectively secured within the patient's intramedullary canal depending on surgeon preference and/or depending on the fracture pattern being treated. In use, the surgeon can elect to either secure the position of the IM nail within the patient's intramedullary canal thereby preventing movement (e.g., medialization) of the IM nail within the patient's intramedullary canal, or the surgeon can allow the IM nail to move (e.g., medialize) within the patient's intramedullary canal.

Abstract: An intramedullary (“IM”) nail for internal fixation of a bone is disclosed. In one embodiment, the IM nail may be a retrograde femoral nail. Alternatively, in another embodiment, the IM nail may be a tibial IM nail. In one or more embodiments, the screw holes are arranged and configured to optimize placement of one or more screws, fasteners, or the like. In addition, and/or alternatively, an IM nail may be arranged and configured to facilitate removal of a broken screw. Alternatively, in some embodiments, the tibial IM nail may be arranged and configured to be side-specific so that the anatomic specific tibial IM nails can be used to, for example, target specific bony anatomy such as, for example, the patient's posterior malleolar, the syndesmotic joint, etc.

Abstract: Logic may provide a deformity analysis to create a treatment plan for external fixators. Logic may further perform additional refinements to the treatment plan to improve the patient experience. Logic may further include pre-operative osteotomy to select an osteotomy and to provide real-time updates to a post-operative image based on changes to an osteotomy line, orientation, and/or rotation point. Logic may facilitate movement of one or two portions of a medical image to determine an alignment of bone segments in the portions of the medical image. Logic may generate deformity parameters based on a combination of translations and/or rotations of the movement to align the portions. Logic may create a treatment plan including a prescription for an external fixator based on deformity parameters.

Abstract: Logic may determine how to reduce bone segments. Logic may communicate one or more images to display with at least two bone segments. Logic may identify a first reduction point and a third point on a first bone segment and identify a second reduction point and a fourth point on the second bone segment. Logic may identify a fifth point on the first bone segment and a sixth point on the second bone segment. Logic may also divide the one or more images along a line or plane between the bone segments, bring the second reduction point and the associated image segment to the first reduction point, align the line or plane of the second bone segment with a line or plane of the first bone segment. Furthermore, logic may adjust alignment and record the movement of the image segments or compare original and final positions, to determine deformity parameters.
