发明名称 Spinal alignment system and related methods
摘要 Spinal alignment apparatus includes bodies that connect to vertebra to be aligned, and elongated elements that connect to the bodies. The elements are adjustable relative to the bodies in multiple dimensions, with locking mechanisms that allow the alignment to proceed in an orderly fashion until a desired degree of correction is achieved. Each elongated element has a shaped end terminating in the first portion of the lockable coupling mechanism. The vertebral connector bodies each include a feature for attaching the body to a respective vertebra, and the second portion of the lockable coupling mechanism. The feature for attaching the body to a respective vertebra may include a pedicle screw or, alternatively, a shape such as a hook adapted for sublaminar engagement. The elongated element also preferably includes a length adjustment mechanism, such as a telescoping or threaded section to provide a desired length in conjunction with a desired degree of alignment. Various coupling mechanisms are disclosed to provide multiple degrees of freedom prior to fixation.
