Methods and devices for static or dynamic spine stabilization include an anterior plating system that allows longitudinal and pivoting motion of the plates and of the stabilized vertebras. In one embodiment a spine fixation assembly for connecting a first vertebra to a second vertebra includes a first plate configured to be attached to one or more locations of the first vertebra and a second plate configured to be attached to one or more locations of the second vertebra. The first plate is pivotally connected to the second plate and may also allow longitudinal and/or horizontal motion of the plates relative to each other.
