Radiofrequency techniques for treating pain

Various radiofrequency procedures are day-to-day invaluable in pain management. This is the best form of trigeminal neuralgia, various types of cancer pain and various spinal pain, including low back pain and neck pain.

Radio frequency (RF) cut is a very high frequency current through a 27 G thermocouple sensor. This probe is introduced through a 20 / 22G cannula (a needle) that is insulated except for its peak. If the high frequency AC (300 kHz) is transmitted through the RF thermocouple sensor, then ionic ions around the RF ion tubes are transmitted to human tissues. This generates electromechanical friction heat. The thermocouple detector does not heat itself up, it actually blurs the heat generated in the surrounding tissue. The heat is completely controlled by the operator. The resulting lesion has a 2-4 mm diameter chopper head shape. Beyond this distance; the electric field is weaker because it is dispersed so no lesions occur.

The temperature and therefore the heat distortion is maximum around the axis and minimum on the summit. On the other hand, the generated electric field is at the top and minimally around the axis. In the traditional RF rhizotomy type we produce heat. In the pulsating RF electrical field, damage is generated. The impulse RF temperature is not increased above 42 ° C. The electrical space causes a small puncture of the holes in the small diameter nociceptive (pain transferring) capacitors. The transmission of the fibers is stopped.

In the conventional type, nerves are regenerated in the future and average painless period variants for the nerve type. In a properly performed lesion, the painless period is 3-4 years. In the pulsating RF, the average pain-free period is 4 to 24 months.

Traditional RF rhizotomy is performed on sympathetic ganglions, purely / primarily in sensory nerves. It always avoids mixed or predominantly motoric nerves. Prior to actual lesion, radiological and electrical tests are performed to prevent the probe from being removed from these nerves against conventional RF infections. Nerve nerves of commonly used RF rheotomy procedures.

first Trigeminal (Gasserian) ganglion and its divinations, ie mandibular nerve and maxillary nerve.

2nd Stellate ganglion

3. Neck sectional artery branch

4. Thoracic facet joint medial branch

5. Splanchnic Nerves

6. Saw Pleated Plexus

7. Excellent Hypogastric Plexus

8. Woody Woody Joints

9. Sacro-Iliac Joints With Nerves

Pulsed RF, as there is no heat dissipation, can be safely performed in most nerve species. This is mostly effective in nerve ganglion, but it is also effective strains. All of the above procedures can be performed except trigeminal ganglions. Especially Dorsal root ganglionostomy. It also happens in mixed peripheral nerves like the suprascapular nerve.
