Spine Flashcards
(30 cards)
Which parts of the spine are lordotic and kyphotic
Lordotic is cervical and lumbar
Kyphotic is thoracic and sacrum
Which ligament runs from c1 -sacrum?
C2-sacrum?
C7-sacrum?
Anterior
Posterior
Supraspinous
Which ligament is in the odontoid?
Which ligament is in cruciform?
Alar
Transverse
Which ligament is in the C-spine?
Which ligament is yellow
Ligamentum nuchae is in the cspine
Flava
What level is the conus medularis
L1/2
Cauda equina
End of conus to sacral/coccyx
Tethered cord
L1/2-S2
What’s purpose of nerve plexuses
Serve motor and sensory needs of the muscles, skin and extremities. Via the dorsal and central rami
What are the four main spinal nerve plexus in what regions?
Cervical C1-c4 muscles of shoulder and neck
Brachial C5 to T1 upper extremity
Lumbar T 12 to L4 lower abdominopelvic region buttox and anterior thighs
Sacral L4- S4 lower trunk posterior thighs and feet
Four main vasculature of the spine
Vertebral arteries/anterior posterior spine
Segmental arteries/spinal rami
Internal venous plexus/cord
External Venus plexus vertebral column
Which ventricle should be include in doing a C-spine
Fourth ventricle
C-spine indications
Myelopathy Cord compression or trauma Spinal infection or tumor Chiari malformation and cervical syrinx MS plaques with in the cord
What’s a common artifact you can have in the spine and what is the name for it in the brain
Gibbs artifact in the spine and truncation in the brain
Why do we do an axial T-2 when looking at MS
To demonstrate the bone marrow
What are the four types of Arnold Chiari malformation
- Tonsils below foramen magnum
- Elongated pons, medulla overlaps the cranial spinal cord m, fourth ventricle downward displaced
- Occipital/ high cervical cerebellar encephalocele
- Cerebellum is hypoplastic
What type of scan should be added when trauma is involved?
GRE to show blood
Do cyst enhance in post contrast
No
Where should you center when setting up Tspine
Use large FOV localizer-sag
Center over xiphoid
Tspine indications
Disc disease Cord compression Ms plaques Cord tumor Inferior extent of cervical syrinx
Positioning for l spine
T11-s2
Make sure the cord is midline
Do you do a T1 or T2 first on Lspine
T2 bc planar Axial look at pathology first
When doing Lspine and see scoliosis or kyphotic what do you do with SS
Stack it
L Spine indications
Diskitis Evaluation of conus Failed back syndrome Hnp/ annular tear Spinal stenosis Tumor/ mass/ trauma Cord termination Disk prolapse Schmorls nodules
Lower back pain syndrome
Sprain, strain, degenerative
Bulging disk
Herniated
