Tracts and Clinical Syndromes | Vascular Supply and Innervation | MOI | Our Patients |
---|---|---|---|
DCML
Vibration and kinesthesia are part of the...
|
Centrifugal and centripetal
What are the two systems involved in the vascular supply to the spine?
|
Least = C spine
Lumbar Thoracic is most stable
List spinal segments from least to most stable
|
LMN - she has flaccid paralysis
Is Gaby with an L1 AIS A SCI UMN or LMN?
|
Anterior Cord Syndrome
Loss of motor, pain, temperature, and crude touch are signs of
|
Sucal = Central
Pial = peripheral
Which specific arteries supply the central and peripheral region of the SC?
|
Highest incidence of neuro injury
Compression anteriorly and distraction posteriorly which may result in a wedge fracture
Describe a C-spine flexion injury
|
UMN
Is Lu Chen UMN or LMN?
|
Central Cord Syndrome
This syndrome typically occurs from a cervical spine injury
|
Up and out
What is the typical spread of SCI?
|
True - because it requires more force to damage this very stable section of the SC
True or False
A traumatic t-spine injury is more likely to be complete? |
Loss of muscle pump
Why may Tom experience lightheadedness and dizziness with transfers from supine to sit and sit to stand?
|
CM involves the sacral cord and lumbar nerve roots where a CE involves the lumbar and sacral nerve roots only
What is the main anatomical difference between conus medullaris syndrome and cauda equina syndrome?
|
ALL hip flexors, partial quad, partial knee flexion
Describe muscle strength for an L3 injury
|
Comminuted fracture of the vertebral body
What is a burst fracture?
|
Hyperreflexive
Frank is T9 incomplete what do we expect his Achilles and quad reflex to be?
|
Diminished kinesthesia
UE strength less than LE strength Low resting HR Not independent with WC mobility
Tom has a C4 AIS D injury with central cord syndrome what do we expect him to look like? (Name 3)
|
C5 - biceps, brachialis
C6 - wrist extensors C7 - triceps C8 - some finger flexion
List C5-C8 muscle that are intact
|
Flexion + rotation + lateral flexion + shear
What is the typical MOI in terms of direction of forces for a flexion with rotation injury? (hint there can be 4 parts)
|
Tom, Frank, Gaby, Lu Chen
