Dorsal Root Ganglion (DRG) Stimulation Therapy

Dorsal Root Ganglion (DRG) Stimulation Therapy

Dorsal root ganglion stimulation therapy is a cutting edge therapy for treatment of complex regional pain syndrome (CRPS) or chronic neuropathic pain in the lower limb including pelvic, groin, hip, knee and foot pain. Traditional spinal cord stimulation does not always provide adequate relief in patients with complex regional pain syndrome or focal neuropathic pain. DRG stimulation is a more specific and targeted therapy for the affected body part. DRG stimulation interrupts pain signals before they reach the spinal cord or brain.

Benefits of DRG therapy

Provide superior and long-term pain relief
Reduce pain an average of 81.4% at 12 months
Provide persistent pain relief to 86% of patients at 12 months
Improve quality of life and the ability to perform every day activities
Eliminate the tingling sensation felt with traditional neurostimulation

How is the procedure performed?

DRG stimulation therapy is done in 2 phases. The 1st phase includes a 4-5 day trial. During the trial the DRG leads are placed in the epidural space behind the affected dorsal root ganglions. During the trial patients are able to control their device. They can increase or decrease the stimulation as needed. At the end of the trial temporary leads will be removed and a decision for permanent implant will be made.

The 2nd phase usually takes place a few weeks after a successful trial. During the procedure the leads and a battery will be permanently implanted. The battery is usually implanted in the lower back. Both phases are done at our ambulatory surgery center under IV sedation.

What are the risks associated with the procedure?

Generally, this procedure is safe and effective. As with all procedures, there are some risks, including:

• Leads might get displaced and you need another surgery to correct the lead placement
• Infection or bleeding
• Cerebrospinal leak and headaches
• New neurological symptoms
