摘要：
Bone anchors providing tensioning between adjacent bones, including a vertebrae. Various embodiments use combinations of bone fasteners and staples to attach a tethering head to a bone. In some embodiments, the tether is attached to the head by means of a separate ring. In still other embodiments the tension in the tether is adjusted by use of a variable depth pocket within the head and/or the bone anchor.
