| Abstract |
|
Complex regional pain syndrome (CRPS) is quite difficult to comprehend and manage, of which etiology and pathophysiological mechanisms have not been fully understood. CRPS is classified as either type 1 (without any known nerve injury) or type 2 (with apparent nerve or tissue injury). Spinal cord stimulation is a restorative therapy that currently offers the best chances of obtaining long-term pain relief in CRPS patients with pain that has not responded to other treatments such as physical therapy or analgesic medications. A 45 years old male patient referred to our pain clinic due to uncontrolled pain at the middle finger for 4 years after crushing injury. He was diagnosed with CRPS type 2 and treated with medication, stellate ganglion block, thoracic sympathetic block, and pulsed radiofrequency therapy, but their effects were transient and not satisfactory. A percutaneous spinal cord stimulation (SCS) with a single quadripolar electrode was tried and the patient's finger pain was improved significantly (from VAS 10 to 2). SCS is an effective treatment for CRPS type 2 which results from crushing injury when alternative therapies fail. |
