Abstract

Device for stabilizing, and/or compressing, and/or distracting certain portions of the spinal column is provided. The device utilizes pedicle screws, and an adapter is provided which may be connected by a screw device to the head of a pedicle screw. A roughened portion of the adapter cooperates with a roughened portion of the pedicle screw head to provide for a non-rotatable connection of the adapter with respect to the pedicle screw. The adapter has a circular opening or a recess for receiving the threaded rod which is fixed to the adapter by a threaded device.
