Dorsal Root Ganglion (DRG) Stimulation

Dorsal Root Ganglion therapy is a form of Neuromodulation and is designed to help manage chronic nerve pain due to Complex Regional Pain Syndrome (CRPS) I and II.  Patients with confirmed nerve injuries are categorized as having CRPS-II, also known as causalgia. Many patients may experience causalgia after surgery or amputation.  During knee surgery or a lower body amputation-even with the utmost care and best surgical techniques-nerves can be injured causing painful neuromas near the amputation/surgical site. Patients without confirmed nerve injury are classified as having CRPS-I (previously called reflex sympathetic dystrophy syndrome or RSDS). 

Either way, the nerve pain that may develop is often long lasting and may heavily impair the quality of life.

The Dorsal Root Ganglion is a cluster of nerve cells along the spine and are responsible for more difficult areas to treat chronic pain. Localized areas that this therapy treats include pelvis, groin, hip, knee, ankle and foot.

DRG therapy works by sending mild electrical pulses to the nerves responsible for the painful sensations.  Outcomes for the patient could include a reduction or a complete block in the pain from the affected nerve to the brain.

DRG Therapy: What to Expect

Trial Before Surgery

DRG therapy can be trialed before committing to another surgery. In the trial period you can assess whether the system:

  • Provides meaningful pain relief
  • Improves your ability to perform daily activities
  • Improves your sleeping habits

What to Expect during and after the procedure

Once a trial has been completed, and you and your physician agree that this therapy is right for you, a pre-op process will begin. This process will include a pre-op physical, insurance pre-authorization, and a scheduled minimally invasive implantation surgery. After surgery, the patient will have post-op appointments including training and programming.
