Background
- Stable cervical spine fracture
- Anterior arch and transverse ligament are unaffected
- Also called a Landells Atlas Type I fracture
- Rule out burst fracture
Mechanism
- Due to forced neck extension
Differential Diagnosis
Vertebral fractures and dislocations types
- Cervical fractures and dislocations
- Thoracic and lumbar fractures and dislocations
Imaging
- Vertical fracture line through posterior arch seen on lateral xray
- CT test of choice to eval for associated fx's
- MRI can evaluate ligamentous injury (transverse ligament is primary AA jxn stabilizer)
Management
- Hard collar for 6-12 weeks
- Neurosurgery may prefer Halo immobilization
- Prehospital Immobilization see NAEMSP National Guidelines for Spinal Immobilization
Disposition
- Usually discharge (if truly isolated) in consultation with neurosurgery
