Abstract:
A scoliosis correction device includes a first fixed anchor that is adapted to be secured to a vertebra of a spine and a second fixed anchor that is adapted to be secured to a vertebra of a spine. A rotatory anchor includes a head portion, a shank portion that extends from the head portion and is adapted to be secured to a vertebra of a spine, and a sprocket that is supported on the head portion for rotational movement relative thereto. A cable extends from the first fixed anchor to the rotatory pedicle screw to the second fixed anchor. The rotatory anchor may be configured to allow unidirectional movement of the sprocket relative to the head portion. A rigid member may extend between the fixed anchor and an intermediate anchor.
