Abstract
A bone anchoring assembly includes at least one fixation plate and at least one bone anchoring element. Each bone anchoring element includes a circular-cylindrical hollow body with an upper end and a lower end, a connecting element that is pivotably mounted to a fixation plate or longitudinal support, an external thread that extends partially along the outer surface of the circular-cylindrical body for anchoring the bone anchoring element into the cortical portion of the bone, and a series of teeth located on the lower end of the circular-cylindrical body for cutting into bone.
