Spinal fixation system

摘要

A spinal fixation system includes a pedicle screw having a longitudinal axis. A fixation element is configured to connect the pedicle screw to at least one additional pedicle screw. A coupling mechanism includes a pedicle screw securing device adapted to secure the coupling mechanism to the pedicle screw and a fixation element securing device configured to secure the coupling mechanism to the fixation element. A fastening mechanism is configured to fasten both the pedicle screw securing device and the fixation element securing device. The fastening mechanism is located along the longitudinal axis of the pedicle screw.
