Abstract
A spinal fixation device includes a threaded stud having an open-ended axial slot to straddle a rod of a vertebral support, and a bracket which is rotatable on the stud. A vertebra bone screw passes through an opening in a distal end of the bracket. The stud and bracket are locked in position relative to the rod by a nut. An insert within the slot bears against the rod and prevents the stud from being deformed by the force of the nut on the stud segments. The bracket can be rotated around the stud; and the stud can be rotated around and slid along the rod, to afford great adjustability and ease of attachment.
