CERVICAL SPINE RTEC 124 WEEK 6 Rev 2010
Review the anatomy
Direction of cervical zygapophyseal joints seen in OBLIQUE seen in LATERAL position
INTERVERTEBRAL FOREAMEN AP = SIDE UP PA = SIDE DOWN
ROUTINE “5 views” (arthritis, etc) AP “ODONTOID” AP (axial) BOTH OBLIQUES, LATERAL (UPRIGHT) SWIMMERS – LATERAL (if needed) ROUTINE “2view” AP (axial) , AP “ODONTOID”, LATERAL (UPRIGHT) SWIMMERS – LATERAL (if needed) TRAUMA CROSS TABLE LATERAL (minimum) “ CLINICAL “ ROUTINE “LATERAL (UPRIGHT) pt is ↑ ┴ C/R PT is ↑ or ↓ AP “ODONTOID” ┴ < C/R (15 – 20 º) ↑ (AP ) AP (axial) BOTH OBLIQUES, SWIMMERS – LATERAL (if needed) pt is ↑ or ↓ POSITIONING FOR CERVICAL SPINE
Done supine or upright
May be more difficult to do upright - use a sponge on back of head to relax neck muscles May need to use a ┴ or C/R < 5º ↑ To move incisors off dens
LATERAL C.SP
With head in true lateral – Look at the mandible position
With head in oblique – Look at the mandible position
“SWIMMERS FOR C.SP TWINNING & PAWLOW METHODS
C/R @ C7- T1 PERP OR ANGLED 5 CAUD
Alternate Positioning FLEXION & EXTENSION Purpose? Flexion and extension views should be obtained in awake and cooperative patients to further evaluate for injury. Flexion views will exaggerate the radiographic abnormalities and extension views will reduce them. Anterior subluxation & check for ROM
Alternate Positioning Fuchs vs Judd Demonstrates? MML ┴ to IR MML // with CR
AP oblique atlanto-occipital joint.
SPINAL INJURY PTan overview :this will be covered in more detail in the TRAUMA lecture
“TRAUMA SERIES” • SHOULD CONSIST OF 2 “views” /projections • 90º TO EACH OTHER • MOVE C/R AND CASSETTE – • NOT THE PATIENT !!! “TAKE IT AS IT LIES” “DO NOT HARM”
When the patient is a true “trauma” care must be taken not to move the patient At a minimum the AP’s & laterals are done with the C.COLLAR in place Then after CLEARED by the MD – you may proceed (?w/o? collar????? ) May be required to repeat AP & Lat again without collar artifact
X-TABLE LATERALSAKA ‘DORSAL DECUBITUS”CERVICAL SPINE Can be done with or without a grid With Comp Rad probably need a grid
Peds pt with comp Dis loc C-2 C-3 Pt died on table
X-table lat –”Swimmers” Note: Mrs. Charman’s tip :Place forearm on forehead to prevent superimposition of humerus + c.sp

Passengers forewarned of an impending rear collision can potentially protect themselves by flexing the neck and tucking the chin against the chest. An extended head potentiates the risk of ligamentous rupture and articular dislocation. Areas of preexisting degenerative disease are most susceptible to injury. radiculopathy- segmental motor or sensory signs associated with a root disorder.
