In Cooled RF, after placement of the introducer needle, the 18 gauge internally cooled RF electrode is used for 90 seconds at a temperature of 60°C.
In conventional RF group lesion will be performed at 80°C for 120 seconds.
In neurolytic block, Once the position of the needle tip confirmed, 4 - 6 mL of 8% phenol in saline will be injected followed by 1 mL of saline to avoid the deposition of phenol within the intervertebral disc material.
Percentage of patients gaining ≥ 50% reduction of their pre procedural pain at VAS Score from baseline value.
Patients rate pain on a scale from 0-10, 0 being no pain and 10 being the worst pain imaginable.
