Abstract
Multi-level spinal stabilization devices, systems and methods are provided that include at least one multi-level connector, one elongated member with an enlarged head, at least one pedicle screw, and at least one mechanism that supports three degrees of rotational freedom relative to both the elongated member and the pedicle screw each. The mechanism may include universal joint mechanisms or ball and socket mechanisms. In the case of the ball and socket mechanisms, the enlarged head of the elongated member cooperates with a first socket member of the multi-level connector to define a dynamic junction that allows the socket member to move relative to the enlarged head of the elongated member while remaining engaged therewith.
