Abstract
Peripheral nerve and dorsal root ganglion stimulation (DRG-s) are effective treatment modalities for focal complex regional pain syndrome (CRPS) that is limited to one or two dermatomes1,2,3. When deciding on a neural target for stimulation, consideration is given to the location of pain, MRI labeling, charge burden of external or internal pulse generator, spinal hardware, and medical comorbidities. While a reduction in pain of fifty percent or greater is often deemed a satisfactory response in the treatment of chronic pain, we describe a case were the patient sought amputation of her limb in the hopes a prosthetic extremity would provide improved function. Despite the risk of post amputation pain, there are patients that seek amputation for advanced CRPS that is refractory to treatment4,5,6. We proceeded with peripheral nerve stimulation (PNS) in addition to her DRG-s system in effort to avoid her upcoming amputation.
