摘要
A spinal system comprising a spinal rod with an outer wall, a proximal end, a distal end, and a first axis extending centrally through the spinal rod between the proximal and the distal ends. The spinal rod comprises a first region having a first modulus of elasticity, a second region having a second modulus of elasticity different from the first modulus of elasticity, and a third region between the first and second region having a modulus gradation ranging from the first modulus of elasticity to the second modulus of elasticity.
