Dorsal Root Ganglion Stimulation as a Treatment for Chronic Refractory Groin Pain: A Case Series.

CRPS can lead to changes in phenotype and function of the DRG. Stimulation of the DRG can block the passage of impulse trains where peripheral and central pathways of pain are modulated, resulting in improved symptoms and quality of life. Groin and perineal pain, refractory to conventional interventions, can be successfully treated with DRG stimulation.
