Abstract
A method for spinal rod insertion includes providing a U-shaped hook tool comprising first and second legs, and inserting the first leg into a first location of a first vertebra and then pushing the hook tool along an arc-shaped path until the first leg exits through a second location of an adjacent second vertebra. Next, providing a spinal stabilization rod and a folded flexible wire comprising first and second open ends at the front end and a closed loop end. The closed loop end is attached to a first end of the spinal stabilization rod and the first and second open ends of the folded flexible wire are inserted into an open end of the second leg of the hook, and the folded flexible wire is threaded through the U-shaped hook and the first and second open ends of the flexible wire exit through an open end of the first leg.
