摘要：
A spinal implant comprises a first rolling-contact core operably coupled to a first vertebra, said first rolling-contact core having a first convex surface having a first axis, said first convex surface configured to provide a first rolling motion in a first direction to said first vertebra relative to a second vertebra. At least one flexure is connected to said first rolling-contact core, said flexure configured to constrain said first rolling motion.
