Cervical Spine DDx 1 Flashcards
Possible causes for cervical instability
- trauma
- RA
- corticosteroid use
- OP
- congenital
- developmental
- postural changes
cervical instability: type of trauma most likely to cause
hyper-flexion injuries
cervical instability: What does prolonged exposure to corticosteroids cause?
- softening of the dens and transverse ligament
- promotes osteoporosis
cervical instability: congenital
Down’s syndrome
cervical instability: developmental
C1-2 of young children naturally unstable
cervical instability: posture
Cadaver studies have indicated that people with marked FHP in life have had anatomic changes in these
dens
transverse ligament

% of cervical fractures that concern the odontoid
15%
odontoid fractures: MOI
- hyperextension
- forceful hyperflexion
- blunt trauma
odontoid fractures: typical presentation
- neck pain
- rarely have neuro symptoms
Most common type
Type II
Type II odontoid fractures are the most common and are (stable/unstable)
unstable
Burst fx of C1 is called
Jefferson fracture
Jefferson fx: typical MOI
axial load
