Abstract

See full text

A pedicle screw is pre-connected to a longitudinal member by an articulation joint. The articulation range is through an angle extending at least from a 90° angle between the longitudinal axis of the pedicle screw and the longitudinal axis of the longitudinal member to an angle sufficiently near a coaxial orientation between those longitudinal axes to permit the first pedicle screw to be screwed into a pedicle of a first vertebra with the longitudinal member attached to the first pedicle screw. A lock fixes the longitudinal member to the first pedicle screw in a selected orientation. A second pedicle screw has an anchor joint with a lock for receiving and being fixed to the longitudinal member after the longitudinal member is rotated into engagement with the anchor joint. The pre-connection with sufficient articulation eliminates the need to connect the longitudinal member to one of the pedicle screws through an incision and assures proper alignment of any bend placed in the longitudinal member.
