Abstract:
A spinal screw assembly adapted to be secured to a vertebrae for providing securement across at least two vertebrae. The assembly includes a pedicle screw having a substantially spherical head portion, a threaded shaft portion, and an engagement surface in the head portion for driving said screw into the vertebrae, and a body member comprising a tower portion having an open top, a break-away section for manipulation of the screw upon implantation into the vertebrae, a base body at a proximal region of the body member and a break zone which acts as a transition between the base body and the tower portion. A resealably securable setscrew within the body member secures and fully contains the rod within said assembly. The break-away section remains completely outside a wound and is removed or broken off once the screw has been fully assembled inside the vertebrae.
