Procedures Spine Review Flashcards
Why do we utilize a 72” SID for lateral projection
Compensate for oid reduce mag
What is preferred SID for XTable lateral projection
10ft
What are 2 ways to move shoulders down for erect lat CSpine
Holding weights
Expiration
Why do we tip chin up for AP CSpine
To superimpose mandible and base of skull to visualize C3-T1
What landmarks are utilized for George projection
Thyroid Cartilage
Gonion
????????
When do you perform a Fuch’s?
When your patient is perfectly positioned, but the tip of the teeth will not clear the dens to visualize the whole thing
What is the main structural difference of C1 compared to all other vertebra
C1 does not have a body. Instead it is replaced by an arch of bone is located where the body is usually found
What region of spine is demonstrated in Swimmers
C3-T3, Cervicothoracic region
PP
Swimmers
pt recumbent true lateral with no rotation of head/shoulders entire spine // to table dependent arm up, under head independent arm down at side
On which projection is breathing technique used
Lateral TSpine
What additional structure is foundon TSpine that is not found on any other vertebrae
Facets and Demi facets for rib articulation
Why do we flex knees for AP LSS
Minimize lordotic curve
Why do we place a lead strip behind the pt for the lateral projection
Minimize scatter
Can-Shaped vertebra is caused by what positioning error on a lateral projection
Spine is not true lateral/parallel to table
What are 2 parts of intervertebral discs
annulus fibrosis
nucleus pulposus
intervertebral foramen are formed by what 2 specific parts
superior and inferior vertebral notches
2 main parts of a typical vertebra
vertebral body
vertebral arch
What is the difference in appearance of spinous processes of C,T,L spine
C-Bifid tips
T-pointy and more vertical
L-more blunt and larger
Scoliosis
Abnormal lateral curvature of the spine
Lordosis
Abnormal lordotic curvature of the lumbar spine
Increased concavity
Kyphosis
abnormal thoracic curvature of thoracic spine
increased covexity
Spondylolysis
breakdown of pars interarticularis
demoed on oblique LSS
spondylolisthesis
Forward slippage of 1 vertebra on another
Usually occurs at L5-S1
Spina Bifida
Failure of 2 lamina to unite causing an opening where the spinous process is usually found
Jefferson’s fx
Comminuted fx
occurs as a result of axial loading
anterior and posterior arches of C1 are fractured as skull slams into ring
Hangman’s fx
fx through pedicles of C2 with or without subluxation of C2-3
occurs when neck is extremely hyperextended
dens is pressing posteriorly into brain stem
Clay shoveler’s fx
caused by hyperflexion of neck
avulsion of spinous processes of C6,7, or T1
Best demoed on a lateral CSpine projection
