Fractures Spine

Jefferson fx

Unstable, Ring fx of C1, lateral masses displacement > 2 mm, transverse ligament rupture, compression (diving); halo x 3 months


Dens fx

  • Type 1: high, Unstable
  • Type 2: base (may look like a Mach line), nonunion
  • Type 3: Unstable, below base
Anterior tilt on lateral view; prevertebral ST swelling, os odontoideum; predental space 3 mm (kids 4-5 mm)


Burst fx

C3-C7, fx fragments into canal - retropulsion, stable unless > 25% of compression


Atlanto-Occipital Dislocation

Unstable, Down Syndrome, prevertebral ST swelling, distance from basion (tip of clivus) to the posterior ring of C1, and distance from opisthion to the anterior ring of C1


Hangman's fx

Unstable, Bilateral pedicle or pars interarticularis fx of C2, hyperextension (hanging, chin on dashboard w/o seatbelt), best seen on lateral view, anterior dislocation of C2, prevertebral ST swelling


Flexion Teardrop fx

Unstable, most severe C-spine injury, C6, C7 levels, ligamentous injury, acute anterior cord syndrome - permanent quadruplegia, teardrop fragment, posterior subluxation of vertebral body, bilateral dislocated facets, spinal process fx, severe compromise of spinal canal, vertebral artery injury


Wedge Compression fx

MRI T2 fat-sat, anterior wedging > 3mm, posterior cortex intact


Bilateral Facet Locks/Dislocation

Unstable, anterior dislocation>50%, all ligaments injured (anterior, posterior, flavum, interspinous); locked --> perched --> subluxated


Unilateral Facet Locks

Stable, < 50% anterior dislocation from simultaneous flexion and rotation, perched, bow-ties, bat-wing appearance


Anterior subluxation

Posterior ligament disruption, widened interspinous distance (fanning)


Extension Teardrop fx

Stable, teardrop fragment from hyperextension


Clay-shoveler's fx

Avulsion fx of C7 spinous process from powerful hyperflexion; if C6, C7 not seen, obtain swimmers view


Chance fx

Lap seatbelt fx, L2, L3, horizontal split of vertebrae, spinous process and intervertebral disk, rupture of ligaments
