Abstract

Spinal stabilization devices, systems and methods are provided that include a stabilization member including a first structural member that mounts to a pedicle screw, a second structural member adjacent the first structural member and that can move away therefrom, a resilient element mounted between the structural members and that elongates to accommodate relative movement therebetween, and a travel-limiting structure mounted between the structural members and that defines and imposes upon the stabilization member a maximum distance by which the first and second structural members may be separated. The travel-limiting structure can include an axially inextensible, laterally flexible elongate element, e.g., wire-rope cable, disposed between the structural members. The resilient element extends between respective first ends of the structural members, while the travel-limiting structure can include terminations at opposite ends of the elongate element and mounted to respective second ends of the structural members opposite the first ends thereof.
