  • 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

  • Cable button
    Patent number: 9763711
    Abstract: The present disclosure includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including cable button threads, a plurality of cable button apertures, a hex socket, and a hex opening. The present disclosure also includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including a plurality of legs, where a leg includes a protrusion, where the protrusion engages the bone plate, and the cable button defines at least one cable button aperture.
