1. An add on surgical screw system for use in surgical procedures, comprising:
a side to side bone screw connector constructed and arranged to engage with and secure to a preexisting implanted bone screw system having a preexisting screw head attached to an anatomical structure without having to remove any components of said preexisting implanted bone screw system, said side to side bone screw connector comprising a vertical body having a flange member at an upper end extending away from said vertical body, said flange member having an opening for receiving a top locking screw, and a preexisting screw head engaging member extending from said vertical body in the same direction as said flange member, said vertical body separating said flange member and said preexisting screw head engaging member by a distance to form a first space, said first space defining a preexisting implanted bone screw system receiving channel sized and shaped to receive and partially enclose therein said preexisting screw head of said preexisting implanted bone screw system, said preexisting screw head engaging member defined by a first member extending away from said vertical body in the same direction as said flange member and a second member extending away from said vertical body in the same direction as said first member, said second member separated from said first member by a second space, said vertical body having a length which positions said first member and said second member underneath said preexisting screw head when said side to side bone screw connector engages with said preexisting implanted bone screw system screw head;
a secondary screw head support member comprising a horizontal body extending from said vertical body in a direction opposite of said first member and said second member of said preexisting screw head engaging member;
a secondary screw head constructed and arranged to receive a secondary surgical rod, said secondary screw head secured to or formed from said secondary screw head support member horizontal body and having two threaded surfaces for receiving a set screw, and a base separating said two threaded surfaces, said base sized and shaped to receive said secondary surgical rod, wherein when said side to side bone screw connector engages or secures to said preexisting implanted bone screw system screw head, said secondary screw head is positioned in a side-by-side orientation with said preexisting implanted bone screw system screw head; and
a locking screw constructed and arranged to fit within said flange member opening and secure to or engage with a preexisting set screw associated with said preexisting implanted bone screw system screw head.
