A method of spinal fixation includes inserting a plurality of screws into at least three vertebral bodies of a spine, the three vertebral bodies defining first and second disc spaces therebetween, and providing a spinal rod having first and second segments that exhibit different properties of flexibility. The spinal rod is connected to the plurality of screws such that the first segment is associated with the first disc space and the second segment is associated with the second disc space.
