Spinal cord stimulation in the treatment of complex regional pain syndrome (CRPS) of the lower extremity: a case report.

UNLABELLED: Complex regional pain syndrome (CRPS) is a condition that is often associated with the extremities. This chronic pain syndrome, when localized to the lower extremity, includes peripheral changes such as edema, temperature alterations, limited range of motion, loss of or excessive perspiration, pain out of proportion to any stimulus, and trophic alterations of the skin, hair, and nails. In this report, we describe the case of a patient who developed complex regional pain syndrome following an ankle injury and surgery. This case report highlights treatment options that are available to patients experiencing complex regional pain, including the use of a spinal cord stimulator. LEVEL OF CLINICAL EVIDENCE: 4.
