Claim Text:
1. A system for the correction of a spinal deformity by derotating one or more vertebrae of the spine, comprising: a rotation rod; a cephalad extender configured to be selectively rotatably coupled to the rotation rod and coupled to a cephalad vertebra of the spine; a caudal extender configured to be selectively rotatably coupled to the rotation rod and coupled to a caudal vertebra of the spine; and one or more intermediate extenders configured to be selectively coupled to one or more intermediate vertebrae of the spine; wherein, when the rotation rod is selectively rotated, a portion of the rotation rod engages a portion of the one or more intermediate extenders, causing the one or more intermediate extenders to rotate about an axis of the spine, thereby causing the one or more intermediate vertebrae to rotate about the axis of the spine; and wherein one or more of the cephalad extender and the caudal extender comprise a locking mechanism for selectively preventing relative rotation with the rotation rod.
