摘要:
The present invention relates to pedicle screw spinal rod connectors and more specifically, a pedicle screw head extender for use with a pedicle screw to ease connection to a spinal rod. The pedicle screw head extenders provided herein can be used with either fixed head pedicle screws or multi-axial head pedicle screws. The pedicle screw head extenders can either be threaded to or snapped into place within the various pedicle screws. It may also be possible to use the present invention with other types of spinal screws that may be connected to spinal rods without the screw actually being implanted through the pedicle of the spine.
