An apparatus for stabilizing vertebrae while permitting a range of motion therebetween may include first and second fasteners for engaging adjacent vertebrae and a motion preserving device that can be coupled to the first and second fasteners. The motion preserving device may include a longitudinal member that includes an array of load-bearing elements. The longitudinal member may be configured to permit the load-bearing elements to move relative to each other and/or relative to other portions of the member. In some embodiments, the longitudinal member is relatively inflexible along a longitudinal axis and relatively flexible in a direction transverse to the longitudinal axis.
