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 upper and lower ends, a hemi-spherical connector that is pivotably mounted to and supported by fixation elements, an external thread that extends partially along the outer surface of the 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 body for cutting into the bone.
