RESUMO
Today, low back pain constitutes one of the most difficult medical problems. Chronic back pain in some patients is refractory to medical, surgical, and behavioral therapy. Persistent or recurrent, chronic pain after spine surgery, referred to as failed back surgery syndrome, can present frustrating cases. When conservative treatments, such as physiotherapy, exercise programs, and epidural steroid injection can not alleviate pain, spinal cord stimulation offers a potentially beneficial treatment option. We describe our experiences on the effects of spinal cord stimulation in a patient with failed back surgery syndrome and a patient suffering from chronic intractable low back pain who obtained satisfactory pain relief and reduction of disability after the implantation of a spinal cord stimulator.
