Patent attributes
An exemplary bone screw includes a proximal section including a first outer thread, a center section including a second outer thread, an unthreaded distal section on an opposite side of the center section from the proximal section, a channel extending from the proximal section to a distal opening of the unthreaded distal section, and at least one side opening extending from the channel to an outer surface of the unthreaded distal section. In some embodiments, the at least one side opening includes a cutting edge configured to cut a material as the bone screw is rotated in a direction for removing the bone screw. In other embodiments, the side opening is formed in at least one of the center section and the unthreaded distal section and includes a diameter that increases in a direction from the channel toward an outer surface of the center section or the unthread distal section. The exemplary bone screws may be used to treat bone fractures with or without a bone plate.
