Abstract
A bone anchoring assembly includes a bone anchoring element having a shank to be anchored in a bone or a vertebra, and a receiving part for receiving a rod. The assembly includes a rod made at least partly of a material which exhibits a material flow under pressure. The receiving part includes a channel with an approximately U-shaped cross-section with two free legs, a first locking element cooperating with the legs to secure the rod in the channel, and a second locking element cooperating with the first locking element and acting independently from the first locking element onto the rod. A pin-shaped projection is provided at the second locking element which comes into contact with the rod when tightening the second locking element, and at least one pin-shaped projection is provided in the channel which comes into contact with the rod when tightening the first locking element.
