Radiofrequency Denervation
(Facet / Sacroiliac)

What is radiofrequency?

Radiofrequency heat is used as a means to lyse (partially stun) nerve tissue. Radiofrequency provides partial to complete interruption of the nerve fibers innervating involved areas and produces significant, lasting relief and a return to normal activity as well as gainful employment.

 

After evaluating the results of diagnostic nerve blocks, such as Lumbar Sympathetic Blocks or Facet Joint Injections, where pain relief has been achieved (even if it is short term reduction/relief of the pain,) the patient may be considered a candidate for the nerve to be destroyed to provide long-term relief of pain.

 

How is the procedure performed?

When the appropriate site is located, a nerve simulator is turned on briefly. The physician looks for movement in the area around the insertion site or for movement in an arm or leg (depending on the nerve to be lysed.) When this has been completed, the physician heats up the needle electrode to lyse the nerve area. The destruction of the nerve interrupts the pathway of the pain impulses to the pain. After several months the nerve begins to regenerate itself, establishing a healthy, pain-free pathway.

 

What should I expect after the procedure?

Patients may be sore around the area of needle electrode insertions for several days. Moist heat, massage, and pain medications may be used to reduce this pain.

Most patients are sent to occupational or physical therapy for instruction on a Home Exercise Program. Patients are usually allowed to increase their activity level over several weeks following the procedure.

 

Who benefits from radiofrequency?

Those who suffer from low back pain, cervical pain syndromes, neuralgias, radiculopathy, headaches, chronic pain involving the sympathetic nervous system, or chronic malignant pain.
