Abstract

The pedicle screw system may be used for fixation of spinal segments and may be advantageous when minimally invasive surgery (MIS) techniques are employed. The pedicle screw system includes a tulip assembly comprising of a tulip body, a inner member, and an expansion member.Installation of the pedicle screw system into pedicles of the spine, for example, includes inserting the pedicle screw into a portion of the spine and then coupling the tulip assembly to the pedicle screw. The tulip assembly may be locked onto the pedicle screw before a rod is placed in the tulip assembly. After the rod is placed in the tulip assembly, the tulip body and the inner member can be rotated relative to one another to lock the rod into the tulip assembly. In addition, the relative rotation may also provide additional locking of the tulip assembly to the pedicle screw.
