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]
Types
- Cervical fracture
- Fracture of C1, including Jefferson fracture
- Fracture of C2, including Hangman's fracture
- Flexion teardrop fracture – a fracture of the anteroinferior aspect of a cervical vertebra
- Clay-shoveler fracture – fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae
- Burst fracture – in which a vertebra breaks from a high-energy axial load
- Compression fracture – a collapse of a vertebra, often resulting in the form of a wedge-shape due to larger compression anteriorly
- Chance fracture – compression injury to the anterior portion of a vertebral body with concomitant distraction injury to posterior elements
- Holdsworth fracture – an unstable fracture dislocation of the thoracolumbar junction of the spine
- Distraction is where there is a pulling apart of the vertebrae.[2] Distraction injuries generally cause breaks in osseous and ligamentous supporting structures, and are therefore generally unstable.[3] A distraction injury on the posterior side of a vertebra can lead to a compression fracture on its anterior side.[3]
Cervical fracture
A medical history and physical examination can be sufficient in clearing the cervical spine. Notable clinical prediction rules to determine which patients need medical imaging are Canadian C-spine rule and the National Emergency X-Radiography Utilization Study (NEXUS).[4]
The AO Foundation has developed a descriptive system for cervical fractures, the AOSpine subaxial cervical spine fracture classification system.[5]
The indication to surgically stabilize a cervical fracture can be estimated from the Subaxial Injury Classification (SLIC).[6]
Thoracolumbar fracture
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.[7]
Thoracolumbar injury classification and severity score
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:[8]
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
Neurology
- Intact - 0 points
- Spinal nerve root injury - 2 points
- Incomplete injury of cord/conus medullaris - 3 points
- Complete injury of cord/conus medullaris (complete) - 2 points
- Cauda equina syndrome - 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.[8]
AOSpine Thoracolumbar Injury Classification System
AOSpine Thoracolumbar Injury Classification System (ATLICS)[9] is the most recent classification scheme for thoracolumbar injuries.[10] ATLICS is broadly based on the TLICS system and has sufficient reliability irrespective of the experience of the observer.[10] ATLICS is primarily focused on fracture morphology, and has two additional sections addressing the neurological grading and clinical modifiers:[9]
Fracture morphology
- Type A: Compression injuries (sub-types A0-A4)
- Type B: Distraction injuries (sub-types B1-B3)
- Type C: Translation injuries
Neurological status
- N0: neurologically intact
- N1: transient deficit
- N2: radiculopathy
- N3: "incomplete spinal cord injury or cauda equina injury"[9]
- N4: "complete spinal cord injury"[9]
- NX: unknown neurological status
Modifiers
- M1: unknown tension band injury status
- M2: comorbidities
