Abstract:
A bone anchoring device includes a bone anchoring element with a spherical segment-shaped head, a receiving part configured to couple a rod to the bone anchoring element, and having a top end, a bottom end, a first passage at the bottom end with a first longitudinal axis, and a second passage at the top end with a second longitudinal axis that intersects the first longitudinal axis, a compression element, and a locking element. The receiving part also has a recess for the rod, the recess extending from the top end towards the bottom end and having a bottom that extends along an axis that is perpendicular to the second longitudinal axis. The receiving part or the compression element further has a seat. The compression element is configured to move along the first longitudinal axis while the locking element is configured to move along the second longitudinal axis.
