Abstract

Dynamic, flexible wrought Nickel/Titanium alloy spinal rods for spinal fusion or dynamic stabilization vertebral implants and methods and processes related to their manufacture. The dynamic and flexibility properties of the wrought Nickel/Titanium alloy spinal rod may be varied by altering processing parameters during manufacture that develop the shape memory characteristics, mechanical properties, and product workability characteristics to achieve custom manufacture of spinal rods having desired flexion in desired lengths. Such a custom manufactured spinal rod may be affixed to an inferior vertebral body at a standard lamina or pedicle location and to one superior vertebral body at a standard lamina or pedicle location using pedicle screws, lamina hooks, or pedicle hooks to provide dynamic stabilization between superior and inferior vertebrae in connection with a spinal fusion procedure.
