Anterior column spinal implants
  • Dynamic stabilization
    • is a concept of placing anchors (generally pedicle screws) into the spine and connecting these anchors with a flexible longitudinal member (e.g. rod, cable, spring).
    • Aim
      • The goal of this type of implant is to constrain but not eliminate motion.
    • Pros
      • Produce less stress on the adjacent spinal segments and may prevent some of the complications observed following spinal fusion (e.g. adjacent-level degenerative changes).
    • Cons
      • Opponents worry that without concurrent spinal arthrodesis, these implants may loosen or fail prematurely and require revision surgery.
        • Currently, there are limited data to prove or disprove the scientific utility of this concept.
