| Cauthen | An articulating spinal implant for intervertebral disc replacement. The articulating spinal implant is formed from two elements, each engaging one of an adjacent pair of vertebra. An articulating mechanism between the two elements resists compression and lateral movement between the vertebra, but allows the adjacent vertebra to articulate about an instantaneous axis of rotation. |
