    摘要: A multi-level spine stabilization system comprises a plurality of securing members configured for attachment to a plurality of vertebrae. A plurality of adjustable rods segments extend between the plurality of securing members. The adjustable rod comprises a first rod segment that engages a second rod segment in an adjustable relationship. The length of the rod may be adjusted by moving the first rod segment relative to the second rod segment. For example, the first rod segment may be in a slideable relationship with the second rod segment such that sliding the first rod segment relative to the second rod segment results in a change in the length of the rod. In one embodiment, portions of both the first rod segment and the second rod segment are positioned within and secured to the securing member. Advantageously, the multi-level spine stabilization system described herein may be used to center dynamic portions of the rod between securing members.
