Abstract

A novel surgical screw is presented as a polyaxial, multiaxial, or monoaxial screw. The polyaxial screw allows versatile angulation between a bone anchor section and a screw body and allows the surgeon to attach a rod to the invention in a top-loading manner and manipulate the rod to accommodate a patient's body and the surgical goals. The screw uses a rod saddle to seat a rod, and permits the surgeon to sagitally manipulate the rod. After implantation of the screw and insertion of the rod, a locking screw is used to fix the angle and position of the rod and screw body.
