  • Patent number: 12251143
    Abstract: An intramedullary nail may include a shank with a centerline defined along a length thereof. The intramedullary nail may also include a channel with a channel axis transverse to the centerline. The channel may have an obround shape in a first cross-sectional plane perpendicular to the channel axis at the centerline and a tapered profile in a second cross-sectional plane containing the channel axis. A proximal edge of the channel within the second cross-sectional plane may form a first angle relative to the channel axis and a distal edge of the channel within the second cross-sectional plane may form a second angle relative to the channel axis that is different from the first angle.

  • Patent number: 12108972
    Abstract: An orthopedic locking screw arranged in a bore of an orthopedic implant enables easy removal of a broken locking screw out of the implant. The orthopedic locking screw for a cooperation with a thread in the orthopedic implant comprises a longitudinally extending shaft. The shaft comprises a thread pattern section extending at least partially along the shaft. The thread pattern section comprises a first thread with a first direction, which is a functional thread configured for the cooperation with the thread in the orthopedic implant. The thread pattern section further comprises a second thread with a second direction opposite to the first direction of the first thread. The second thread is superimposed on the first thread and intersects the first thread. An orthopedic locking system comprises the orthopedic locking screw and the orthopedic implant. The locking screw is manufactured by applying the thread pattern section to the longitudinally extending shaft.
