Dorsal Root Ganglion Stimulation

Precise pain relief for small, hard-to-treat areas.

What Is Dorsal Root Ganglion (DRG) Stimulation?

Dorsal Root Ganglion (DRG) stimulation is a targeted neuromodulation therapy designed to manage chronic, localized neuropathic pain. By delivering mild electrical pulses to the dorsal root ganglia—clusters of sensory nerve cells along the spinal column—DRG stimulation can effectively interrupt pain signals before they reach the brain. This therapy is particularly beneficial for patients with focal pain conditions that have not responded to conventional treatments.

This therapy is particularly beneficial for patients with focal pain conditions that have not responded to conventional treatments.

How DRG Stimulation Works

The DRG stimulation system comprises:

✔ Leads: Thin, insulated wires placed near the dorsal root ganglia corresponding to the area of pain.

✔ Implantable Pulse Generator (IPG): A small device implanted under the skin, typically in the buttock or abdomen, which generates electrical pulses.

✔ Patient Controller: A handheld device allowing patients to adjust stimulation settings within prescribed limits.

Benefits of DRG Stimulation

DRG stimulation offers several unique advantages for patients with focal, chronic pain. Its precision and flexibility make it an effective option when other treatments fall short.



Targeted Pain Relief

Offers precise modulation of pain signals in specific areas, such as the foot, knee, or hip.



Improved Quality of Life

Patients experience less pain, with better mobility and daily function.



Reduced Side Effects

Lower stimulation amplitudes are required, minimizing unwanted sensations like paresthesia.



Reversible and Adjustable

The system can be turned off or removed, and settings personalized.

Conditions Treated with DRG Stimulation

DRG stimulation is effective in managing various chronic pain conditions, including:



Complex Regional Pain Syndrome (CRPS)

A chronic pain condition often affecting limbs, characterized by severe pain, swelling, and changes in skin color or temperature.



Causalgia

Severe, persistent pain following nerve injury, typically in the limbs.



Peripheral Neuropathy

Nerve damage causing pain, tingling, or numbness, especially in the hands and feet.



Post-Amputation Pain

Pain perceived in a limb that has been amputated, including phantom limb pain.



Post-Surgical Pain

Persistent pain following surgical procedures, particularly in the spine or joints.

What to Expect During the Procedure

01 Before the Procedure

✔ Comprehensive evaluation of medical history and pain condition.

✔ Imaging studies to determine the appropriate placement of leads.

02 During the Procedure

✔ Performed under local anesthesia with sedation.

✔ Leads are placed near the targeted dorsal root ganglia using fluoroscopic guidance.

✔ The IPG is implanted under the skin in the buttock or abdomen.

✔ The procedure typically takes less than two hours and is done on an outpatient basis.

03 After the Procedure

✔ Patients can usually return home the same day.

✔ Follow-up appointments are scheduled to monitor progress and adjust settings as needed.

✔ Most patients experience significant pain relief within days of activation.

Ideal Candidates for DRG Stimulation

You may be a good candidate for DRG stimulation if:



You have chronic, localized pain lasting six months or more.



Traditional treatments (medications, physical therapy, nerve blocks) have not provided adequate relief.



You seek a non-opioid, minimally invasive pain management option.



You do not have medical conditions that could interfere with the implantation procedure.

Risks and Potential Side Effects

While DRG stimulation is generally safe, potential risks include:



Surgical Risks

Infection, bleeding, or nerve damage at the implantation site.



Device-Related Issues

Lead migration, device malfunction, or discomfort at the implant site.



Stimulation Side Effects

Unwanted sensations, such as tingling or muscle twitching, which can often be managed by adjusting settings.
