A)
The plasma field is an ionized gas consisting of free
electrons, ions and excited radicals.
B) In contact with biological tissue,
    these   plasma particles are
    sufficiently (re)active to disintegrate
    organic molecular within the tissue
    into elementary molecules
C) In this manner, the target tissue is
   effectively dissolved or volatilized in
   a gentle fashion (at low temperature)
   inducing no damage to surrounding
   healthy tissue.

Radicular Pain (Lateral herniation)
    - Arm pain
    - MRI evidence of contained disc protrusion
    - Not surgical indicated (motor weakness, etc.)
    - Failed Nerve Block.
Axial Neck Pain (Central focal herniation)
    - Failed conservative therapy for 3 months
    - Discography positive for concordant pain
    - Disc height > about 75%
Red flag
     - Spinal fracture, tumor, infection
     - Central cord lesion
Benign Lesion
     - 50% loss of disc height
     - Extruded or Sequestered disc
     - Moderate to Severe spinal stenosis
     - Complete annular disruption
     - Degenerative instability
     - Herniation greater than 1/3 the diameter of the spinal canal

More Ablation is needed due to large disc.
Curved catheter is required. It is Technically Complicated.

Ablation procedures like PPDD and Coagulation are effective methods for treating various conditions such as cardiac arrhythmias, tumors, and wound debridement. RF ablation offers advantages such as precise targeting, lower tissue temperatures, and tissue preservation at the molecular level. Understanding plasma and its role in generating heat for ablation is crucial in these medical interventions.
