What is DRG stimulation?
The dorsal root ganglion is a cluster of nerve-cell bodies that helps carry sensory signals toward the spinal cord. DRG stimulation delivers small electrical pulses through implanted leads to change how pain signals are processed.
Who may be considered?
In the United States, the approved indication for the Abbott DRG system includes adults with moderate to severe, persistent lower-limb pain associated with complex regional pain syndrome (CRPS) types I and II. An evaluation is needed to determine whether the diagnosis and treatment history support this option.
Trial and implantation
A temporary trial helps assess pain relief and daily function before a permanent implant is considered. An implanted system requires programming, follow-up and instructions on using the controller.
Benefits and considerations
The goal is improved pain control and function; benefit is not guaranteed. Risks include infection, bleeding, nerve injury, lead movement and device problems. MRI eligibility depends on the exact implanted system and scanning conditions. Tell every treating clinician that you have a stimulator.
