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.
