摘要：
Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes a tensioning mechanism adapted to couple to a tether extending along a path between at least two bone anchors implanted in adjacent vertebrae. The tensioning mechanism can be adapted to apply a tensioning force to the tether along the path of the tether to thereby move the tether along the path. The device further includes an actuation mechanism movably coupled to the tensioning mechanism such that the actuation mechanism is adapted to effect movement of the tensioning mechanism to control the tensioning force applied to the tether.
