The Spinal Cord Stimulation (SCS) has been used since 1967 for the treatment of drug resistant chronic pain. The evidence of efficacy of this technique has been demonstrated. In lumbar Failed Back Surgery Syndrome (FBBS) and in Complex Regional Pain Syndrome (CRPS). Despite the results the rate of SCS complications is high ranging from 8% to 75%. Usually the complications are divided in biological as infections or seroma and hardware related as lead fracture or Implantable Pulse Generator (IPG) malfunction.
Between biological complications there is pain or discomfort around the IPG site or pain over the lead anchor or connectors between IPG and electro catheters. These complications are present in the clinical series with a frequency of 0.9% to 12% .Temporary pain due to processes of incision healing or due to disruption of body tissue during implantation procedures usually improves after 7-14 days. However this pain can be present within weeks or months from implantation.
