Hangman's fracture
Background
- Also known as traumatic spondylolisthesis
- Is an unstable spine injury
- Bilateral C2 pedicle fracture (leads to C2 displacing anteriorly on C3)
Vertebral fractures and dislocations types
- Cervical fractures and dislocations
- Thoracic and lumbar fractures and dislocations
Clinical Features
- Seen in MVA, diving accidents, but uncommonly judicial hangings (not in suicidal hangings)[1]
- Forced extension of an already extended neck
- Spinal cord damage is often minimal (diameter of neural canal is greatest at C2)
Differential Diagnosis
Neck Trauma
- Penetrating neck trauma
- Blunt neck trauma
- Cervical injury
- Neurogenic shock
- Spinal cord injury
Evaluation
- Xray or CT cervical spine
Management
Prehospital Immobilization
Hospital
- C-collar
- Consult ortho or neurosurgery
- External fixation via rigid cervical orthosis or halo-vest orthosis 8-14 weeks (~90% healing with immobilization alone) [2]
- Surgical fixation, especially if there is:[3]
- Severe angulation of C2 on C3
- Disruption of C2 to C3 disc space
- Inability to establish or maintain alignment with external immobilization
- Nonunion after use of external immobilization
Disposition
- Admit
