摘要：

A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. Hydraulic extension of extendable members permit the cage to conformably engage between vertebral bodies to effectively distract the disc space and rigidly fix the spine.
