Abstract: A bone anchoring assembly and method for attaching a body part to a patient's bone which includes a bone anchor that is implantable in bone having an opening leading to a cavity formed therein. A coupling member with at least one portion made of a shape memory material having a transformation temperature range. The coupling member is movable through the opening and in and out of the cavity at temperatures below the transformation temperature range. With it in the cavity and at temperatures above the transformation temperature range, the coupling member is locked within the bone anchor. The coupling member is attachable to the body part.
