The Surgical “Grid”

These are four groups of patients:

  • IA—Structural lesion, low risk for chronic pain
  • IB—Structural lesion, at risk for chronic pain (high stress)
  • IIA—Non-structural lesion, low risk for chronic pain
  • IIB—Non-structural lesion, at risk for chronic pain (high stress)
  • An overview of how this looks is presented in this grid:
