Spine Study Guide Flashcards
Canadian C-Spine Rules
high risk factors (> 65, dangerous mech, paresthesia)
- yes, radiography
NO –> low risk factors that allow for safe assessment for ROM (can sit, ambulatory, absence of midline tender, delayed onset of pain)
- no, radiography
YES –> B rot > 45
- no, radiography
YES - no radiography
C-Spine Fxs
Jefferson/Burst - C1
Odontoid - C2
Hangman’s - C2 (post aspect, usually w/ lysthesis)
Clay Shoveler’s - spinous process of C6-T2 (hyperflex)
C-Spine Dislocation
more frequent than fx
C - violent flex/rot
E - neck tilted toward side of dislocation
Cervical Myelopathy
Hoffman’s, hyperreflex of brachiorad, gait disturbance, Babinski, > 45
Cervical Radic Test Cluster
Positive - cervical distraction test - spurling's - ULTT median < 60 rot to affected side

C-Spine X-rays
Lateral (initial) - alignment, spacing soft tissues/vertebrae
A/P - alignment, oblique fx
Odontoid - C1-C2 relationship
Swimmer’s - C7-T1
ADI
3-5 instability
> 7 disruptions of transverse ligament
> 9-10 risk of neurologic injury (often needs surgery)
important with trauma, Down syndrome, RA
Stinger/Transient Quadriplegia (CET)
Associated with cervical stenosis, kyphosis, congenital fusion, cervical instability, herniation, vascular/metabolic abnormalities
C - stretch/traction of brachial plexus; ext w/ root compression, direct blow to plexus
