What is Dorsal Root Ganglion Stimulation and How Does It Work?

Dorsal root ganglion stimulation therapy, often abbreviated as “DRG stimulation,” is a targeted form of pain treatment designed to treat nerve related pain, commonly from prior surgery or a past injury. It works by using electrical impulses from electrodes placed near the large nerves just prior to the nerves entering the spinal cord, to help block the pain signals that travel on those nerves on their path to the brain. By interfering with these nerve impulses, patients experience diminished pain.

Dorsal root ganglion stimulation is a two-part process where a trial period is performed prior to any permanent surgical procedure being performed. This allows patients to try the therapy by undergoing a minimally invasive procedure without surgical incisions. If the trial period is successful, patients will be set up for the permanent implant. Both procedures are performed safely with local numbing medication and mild sedation.

What does Dorsal Root Ganglion Stimulation treat?

Dorsal root ganglion stimulation is designed to treat nerve related pain in a specific location of the body. Common indications for dorsal root ganglion stimulation are chronic knee, ankle, groin, pelvic floor, and lower abdominal pain. It is commonly used to treat residual pain following hernia surgery, knee replacement surgery, foot and/or ankle surgery or trauma.

What to Expect from Dorsal Root Ganglion Stimulation

Patients can expect a significant reduction in their nerve related pain with a long term therapy that can eliminate the need for recurring injections and medication refill appointments. The stimulation of the nerves is not generally sensed by the patient, and patients will simply sense a reduced level of pain.

The Risks of DRG Stimulation

The risks of dorsal root ganglion stimulation trials and implants are very low. Like any procedure, there is a small chance of bleeding and infection, and multiple steps are taken to minimize these risks. Imaging guidance is used for both the trial and implant, to reduce risks.

How long will the benefits last?

arrow icon

The benefits of dorsal root ganglion stimulation are constant and long-term, lasting for many years as long as the device is on. There is potential that the battery for the device may need to be replaced with a minor procedure in about 7-10 years after the initial implant and this allows the device to provide decades of relief.

How long does the procedure take?

arrow icon

The dorsal root ganglion stimulator trial procedure takes between 30-60 minutes to complete, and patients will have the device for 1 week with an external battery taped to their back. The dorsal root ganglion stimulator permanent implant procedure takes 60-90 minutes and the device will remain implanted for as long as the patient desires.

What conditions or chronic pain issues can Dorsal Root Ganglion Stimulation therapy help with?

Dorsal Root Ganglion Stimulation therapy can help manage various chronic pain conditions, such as complex regional pain syndrome, post-surgical pain, and neuropathic pain, particularly in areas like the lower back, legs, or feet.

How does Dorsal Root Ganglion Stimulation therapy compare to other pain management treatments or options?
