More Information
Summary:A bone screw is provided that reduces insertion torque when driving the screw into bone while maintaining pull-out strength. The provided bone screw includes one or more threads having a portion with a reduced flank profile that helps reduce the amount of torque required to drive the bone screw into bone. The portion with the reduced flank profile has an equal thread depth or height as the portion of the one or more threads with a non-reduced flank profile, thereby helping to maintain pull-out strength. The reduced flank profile portion is away from the bone screw's insertion tip. As such, the bone screw's non-reduced flank profile portion creates internal female threads that have a correspondingly larger flank profile than the screw's reduced flank profile portion, thereby reducing friction between the reduced flank profile portion of the one or more threads and the interior female thread.
