|
this fracture results from hyperflexion of the neck and results in avulsion fractures on spinous process, best demo. on a lateral c-spine

Compression fracture
|
|
occurs when the neck is subjected to extreme hyperextension, best demo. by a lateral c-spine
|
Hangmans's fracture
|
|
this comminuted fracture (splintered or crushed at site of impact) occurs b/c of axial loading, best demo. on an AP open mouth & lateral projections.
