A spinal fracture, also called a vertebral fracture or a broken back, is a fracture affecting the vertebrae of the spinal column. Most types of spinal fracture confer a significant risk of spinal cord injury. After the immediate trauma, there is a risk of spinal cord injury (or worsening of an already injured spine) if the fracture is unstable, that is, likely to change alignment without internal or external fixation.[1]


Risk of spinal cord injury[edit]

Vertebral fractures of the thoracic vertebrae, lumbar vertebrae or sacrum are usually associated with major trauma and can cause spinal cord injury that results in a neurological deficit.[4]

Thoracolumbar injury classification and severity score[edit]

The thoracolumbar injury classification and severity score (TLICS) is a scoring system to determine the need to surgically treat a spinal fracture of thoracic or lumbar vertebrae. The score is the sum of three values, each being the score of the most fitting alternative in three categories:[5]

Injury type

  • Compression fracture - 1 point
  • Burst fracture - 2 points
  • Translational rotational injury - 3 points
  • Distraction injury - 4 points

Posterior ligamentous complex

  • Intact - 0 points
  • Suspected injury or indeterminate - 2 points
  • Injured - 3 points


A TLICS score of less than 4 indicates non-operative treatment, a score of 4 indicates that the injury may be treated operatively or non-operatively, while a score of more than 4 means that the injury is usually considered for operative management.[5]

AOSpine Thoracolumbar Injury Classification System[edit]

AOSpine Thoracolumbar Injury Classification System (ATLICS)[6] is the most recent classification scheme for thoracolumbar injuries.[7] ATLICS is broadly based on the TLICS system and has sufficient reliability irrespective of the experience of the observer.[7] ATLICS is primarily focused on fracture morphology, and has two additional sections addressing the neurological grading and clinical modifiers:[6]

Fracture morphology[edit]

  • Type A: Compression injuries (sub-types A0-A4)
  • Type B: Distraction injuries (sub-types B1-B3)
  • Type C: Translation injuries

Neurological status[edit]

  • N0: neurologically intact
  • N1: transient deficit
  • N2: radiculopathy
  • N3: "incomplete spinal cord injury or cauda equina injury"[6]
  • N4: "complete spinal cord injury"[6]
  • NX: unknown neurological status


  • M1: unknown tension band injury status
  • M2: comorbidities
