Abstract
A minimally invasive and open surgery surgical system for implanting spinal screw assemblies to be connected by a spinal rod is disclosed. In one form, the system includes an improved tool device for inserting a cap insert into an initial and final locking of a screw assembly and securing a spinal rod inserted through an incision to a vertebra. In another form, the system also includes a screw fixation system that allows greater variability in thread diameter for orthopedic implant for in the spine, iliac crest, or bones.
