[Interventional pain management, indications and results].

When conservative treatment modalities provide inadequate relief, interventional techniques play an important role in the management of chronic pain patients. They are performed in diagnostic or therapeutic intention (or both) and either directly target the pain generating anatomic structure (e.g. intraarticular joint injections) or the neural structures which are thought to mediate the experience of pain (e.g. facet joint nerve blocks, spinal cord stimulation). In order to enhance precision and patient safety, these interventions are performed with image guidance; of which fluoroscopy is the most commonly used technique. CT- or Ultrasound-guided techniques are also performed. This article is an overview of the indications and results of the most commonly performed interventional techniques used in chronic pain treatment with focus on spinal interventional procedures.
