Abstract
A pedicle screw system includes a pedicle screw and a tulip assembly. A rod is inserted and fixed in the pedicle screw system to surgically connect vertebral bodies. The pedicle screw includes a head portion and a threaded shaft. In one embodiment, the tulip assembly includes a tulip body, a rod-support member, a collar member, a cap, and a fastening member. The tulip body has an upper portion and a lower portion, these portions being displaceable in opposite directions relative to an intermediate web. The tulip body can be intra-operatively coupled to the pedicle screw after the screw has been inserted into the bone. The cap engages with the tulip body to lock the tulip body onto the pedicle screw and thus fix the tulip body at a desired angle relative to the pedicle screw.
