Abstract

A spinal implant device comprising a frame and a plurality of mechanical stiffness members extending from the frame, with the plurality of mechanical stiffness members being individually customized to provide a specific axial stiffness. The plurality of mechanical stiffness members may be coupled to the frame, and the plurality of mechanical stiffness members may be a plurality of wave-spring modules. A method of treating spinal disease includes determining actual spatial mechanical properties across a vertebral contact surface of a vertebra of a patient. The method may also include manufacturing a spinal implant device that has conforming spatial mechanical properties that are specific to the patient and that are based on the actual spatial mechanical properties of the vertebral contact surface. The method may include surgically implanting the spinal implant device against the vertebral contact surface such that the actual spatial mechanical properties and the conforming spatial mechanical properties align.
