Clinical Context
A patient presents with acute post-thoracotomy pain or other acute postprocedural pain localized to the cervical or thoracic spine. The provider, typically an anesthesiologist, pain medicine physician, or spine surgeon, determines that a transforaminal epidural injection is indicated to manage the pain.
