  • Publication number: 20240374296
    Abstract: An intramedullary nail includes one or more nail openings extending therethrough. The intramedullary nail is implantable within a medullary canal of the bone. A bone plate is configured to engage an outer surface of the bone. The bone plate includes one or more plate openings extending therethrough. The plate openings are spaced about the bone plate such that the bone plate is positionable to axially align the plate openings with the nail openings when the intramedullary nail is implanted within the medullary canal of the bone. An aiming guide includes one or more targeting openings. The targeting openings are spaced about the aiming guide such that the aiming guide is positionable to axially align the targeting openings with the plate openings and the nail openings for extending one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone.

  • Publication number: 20240350171
    Abstract: The present technology relates generally to ring fixators and associated systems and methods. In some embodiments, for example, a ring fixator assembly comprises a ring configured to surround a fractured bone, a retention device disposed at a first position on the ring, and a tensioner clamp disposed at a second position on the ring. A wire extends between the retention device and the tensioner clamp. The tensioner clamp includes a first screw configured to secure the wire in position with respect to the tensioner clamp and a second screw configured to apply additional tension to the wire.

  • Publication number: 20240148418
    Abstract: Described herein are retrograde femoral nails and insertion systems suitable for stabilizing femoral fractures of the shaft and femur. After reaming the femoral canal, the intramedullary nail may be inserted with a retrograde approach through the knee. The nail includes four-start threaded holes in the distal region. The nail also includes oblique distal holes with a trajectory that targets the bone in the posterior condyles. The insertion instrumentation assembly and system includes an insertion handle with a retaining thread that prevents the connection bolt from falling out. An assembly shaft is also included, which assists the user in connecting the nail to the insertion handle. The system further includes an aiming guide with a retention mechanism that holds driver sleeves in place. The aiming guide also contains a hole to position a locking washer holder to interface with the nail.
