Cervical Spine Fractures
MECHANISMS
- Hyperflexion
- Hyperflexion and rotation
- Hyperextension
- Hyperextension and rotation
- Vertical compression and burst injury
- Lateral flexion
- Direct shearing
- Penetrating
- Other
- burst # of atlas (C1)
- combined anterior and posterior arch fractures
- from axial compression of C1
- can result from hyperextension causing a posterior arch #
- typical history: diving head first into water, thrown against roof of car
- unstable
HANGMAN FRACTURE
- bilateral fracture of the posterior arch of C2 and disruption of the C2-3 junction
- neurological injury may result from damage to the posterior longitudinal ligament allowing significant anterior displacement of C2 on C3
- from hyperextension with vertical compression of the posterior column
- typical history: car accident with patient striking head on dashboard
- unstable
CLAY SHOVELLER FRACTURE
- fracture of one or more of the spinous processes of the C6-T3 vertebra
- avulsion fracture by the supraspinous ligament of the spinous process caused hyperflexion
- stable
