Spinal injuries are generally described in three parts according to the injured area: upper cervical (from the skull base to the second vertebra), lower cervical (from the third to the seventh vertebra), and thoracolumbar. Various classifications have been proposed for each area depending on the type and mechanism of injury, which can suggest prognosis and treatment. Understanding these classifications is essential for determining which areas to focus on in imaging. However, various researchers have proposed different classifications, which can be confusing for beginners as to which classification to use for imaging evaluation. This chapter focuses on learning imaging findings according to the most widely used classifications in clinical practice for spinal injuries.
