Publication number: 20230200871Abstract: Periprosthetic bone plates are disclosed including, for example, a periprosthetic distal femur plate. In use, the bone plate is configured for use in periprosthetic fractures. That is, the bone plate includes one or more features to facilitate positioning and securement of the bone plate to a patient's bone that previously received a surgically implanted orthopedic implant such as, for example, an intramedullary nail, a hip prosthesis, a knee prosthesis, etc. In use, the one or more features are designed and configured to facilitate avoidance of the previous surgically implanted orthopedic implant. In addition, the bone plate is configured to facilitate percutaneous insertion of the bone plate against the patient's bone while minimizing soft tissue irritation. In addition, and/or alternatively, the bone plate is configured to provide improved contouring to facilitate better positioning of the bone plate against the patient's bone (e.g., better contouring adjacent patient's greater trochanter).Type: ApplicationFiled: May 17, 2021Publication date: June 29, 2023Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20230165609Abstract: 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.Type: ApplicationFiled: May 5, 2021Publication date: June 1, 2023Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20230142959Abstract: A bone plate incorporating a length adjusting elongate hole formed in a shaft portion thereof, along with corresponding methods of use. In one embodiment, the length adjusting elongate hole is configured to receive one or more bone fixation devices (e.g., bone screws). In use, the bone fixation device positioned within the length adjusting elongate hole may be partially loosened, without removal, to enable the patient's bone to be adjusted (e.g., loosening the bone fixation device within the length adjusting elongate hole allows the surgeon to adjust the position of the patient's bone, and hence the bone fixation device coupled thereto, relative to the bone plate). Once properly adjusted, the bone fixation device positioned within the length adjusting elongate hole may be retightened. In various embodiments, the length adjusting elongate hole is configured so that, in use, each of the plurality of bone fixation openings remains available to a surgeon.Type: ApplicationFiled: April 15, 2021Publication date: May 11, 2023Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.
