Dorsal root ganglion stimulation (DRGS) therapy is a rapidly emerging tool being used by pain physicians in the treatment of chronic pain. Complex regional pain syndrome (CRPS), a debilitating disease whose mechanism is still has yet to be fully elucidated, is a common pathology targeted by DRGS therapy, often better results than traditional spinal cord stimulation. DRGS therapy, however, is not bereft of complications. Lead migration and fracture are two examples in particular that are among the most common of these complications. The authors report an unusual case of lost efficacy due to lead fractures in patients with CRPS treated with DRGS. The case report narrates identification, management and probable mechanism of DRGS lead fracture. The structural instability of DRGS leads can yield distressing symptoms at any point during the therapy, and physicians should be cognisant of the complications of DRGS therapy.

Intravenous Ketamine

In this case report, we describe the effect of ketamine infusion in a case of severe refractory complex regional pain syndrome I (CRPS I). The patient was initially diagnosed with CRPS I in her right upper extremity. Over the next 6 years, CRPS was consecutively diagnosed in her thoracic region, left upper extremity, and both lower extremities. The severity of her pain, combined with the extensive areas afflicted by CRPS, caused traumatic emotional problems for this patient. Conventional treatments, including anticonvulsants, bisphosphonates, oral steroids and opioids, topical creams, dorsal column spinal cord stimulation, spinal morphine infusion, sympathetic ganglion block, and sympathectomy, failed to provide long-term relief from pain. An N-methyl-d-aspartate (NMDA) antagonist inhibitor, ketamine, was recently suggested to be effective at resolving intractable pain. The patient was then given several infusions of intravenous ketamine. After the third infusion, the edema, discoloration, and temperature of the affected areas normalized. The patient became completely pain-free. At one-year of follow-up, the patient reported that she has not experienced any pain since the last ketamine infusion. Treatment with intravenous ketamine appeared to be effective in completely resolving intractable pain caused by severe refractory CRPS I. Future research on this treatment is needed.

This is a case of a 54-year-old man presenting with complex regional pain syndrome (CRPS) type 1 of the right lower extremity, which was most debilitating in the plantar aspect of the right foot. The patient had prior treatment with thoracic spinal cord stimulation; however, the foot pain remained intractable. Given that his pain was predominantly in his foot and remained debilitating despite thoracic spinal cord stimulation, it was recommended that the patient undergo a trial of dorsal root ganglion (DRG) stimulation. The surgical technique for placement of dorsal root ganglion stimulators is demonstrated in this operative video.The video can be found here: https://youtu.be/_1xMxFZa6tU
