    摘要: A method and apparatus for aligning and fixing vertebral bodies is provided. The vertebral alignment/fixation assembly (10) of the current invention comprises a hemispherical headed pedicle screw (12) disposed within a slotted coupling unit (14) designed to allow angular adjustment of the pedicle screw (12) up to 90 degrees and which may be securely locked into position via a single threaded locking nut (16) once a standard alignment rod (60) has been inserted into the slotted coupling unit (14). The vertebral alignment/fixation assembly (10) enabling the angular adjustment of the fixation system hardware after final placement and insertion of the pedicle screw (12) into the vertebral body. A system and method for aligning and fixing vertebral bodies using the vertebral alignment/fixation assembly of the invention is also provide.
