  • Bone screw with multiple thread profiles for far cortical locking and flexible engagement to a bone
    Patent number: 10918430
    Abstract: Osteosynthesis constructs for treating bone fractures and bone screws for use in such systems are disclosed. The bone screws include a threaded front section configured for engagement with cortical bone, a threaded mid-section and an unthreaded neck section configured for limited movement within the near cortex of the bone. Osteosynthesis constructs of the type disclosed promote secondary healing by allowing for substantially parallel motion at the near and far cortex within the effective motion range for callus formation.
    Type: Grant
    Filed: April 13, 2016
    Date of Patent: February 16, 2021
    Assignee: Zimmer, Inc.
    Inventors: Michael Bottlang, Michael K. Keith, Josef Doornink, Anthony Lee Koser
