Bone anchoring methods and systems employed by such methods. The bone anchoring methods involve implanting a vertebral adjustment system into a vertebral body of a patient. The vertebral adjustment system includes a flexible member and a tensioning mechanism coupled to the flexible member. The tensioning mechanism is capable of imparting a force on the flexible member to change the tension of the flexible member. The methods include the step of engaging the tensioning mechanism to the flexible member, enabling the flexible member to be tensioned and secured in place.
