  • Publication number: 20240285318
    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.
