Abstract

See full text

Growing rod systems and methods for correcting spinal deformities include at least one growing rod assembly and at least one fluid delivery assembly. Each growing rod assembly includes a fluid actuator that is operable to extend first and second rod segments in opposite directions along the spine. The fluid actuator can be provided by, for example, a piston-cylinder actuator. Each fluid delivery assembly includes a fluid pump operably connectable to a fluid line, which in turn is connected to the fluid actuator. In one embodiment, the fluid actuator is of a linear design. In another embodiment, two linear or curvilinear fluid actuators are provided back-to-back and connected by a connecting rod that mounts to the mid-spine and is contourable. In another embodiment, the fluid actuator is of a curvilinear design to generally conform the normal spine. And in another embodiment, the fluid actuator includes a fluid-over-fluid shock absorber.
