Spinal Cord Injury Flashcards
Where does the spinal cord begin and end?
1 - medulla oblongata to L1
2 - medulla oblongata to L4
3 - pons to L1
4 - pons to L4
1 - medulla oblongata to L1
What is the name given to the end of the spinal cord at L1?
1 - cauda equine
2 - caudate
3 - conus medullaris
4 - internal capsule
3 - conus medullaris
- terminal end of the spinal cord
What is the most common site of the spine that has a major spinal injury?
1 - cervical
2 - thoracic
3 - lumbar
4 - sacral
1 - cervical
A spinal cord injury is defined as an injury that causes temporary or permanent changes in the spinal cords function. What % of spinal cord injuries are cervical?
1 - 5%
2 - 25%
3 - 50%
4 - >75%
3 - 50%
A spinal cord injury is defined as an injury that causes temporary or permanent changes in the spinal cords function. Spinal cord injuries have a bimodal distribution. Why is this?
1 - young and older patients have brittle bones
2 - diseases are more likely in older and younger patients
3 - young more likely for major trauma, and old more likely for minor and degenerative trauma
3 - young more likely for major trauma, and old more likely for minor and degenerative trauma
A traumatic spinal cord injury is a lesion of neural elements of the spinal cord that can result in any degree of sensory and motor deficit, and autonomic or bowel dysfunction. What does tetraplegia mean?
1 - loss of movement and sensation on one side of the body
2 - loss of movement and sensation in all limbs
3 - loss of movement and sensation in lower limbs
4 - loss of movement and sensation in upper limbs
2 - loss of movement and sensation in all limbs
- tetraplegia =
- tetra is greek for four
- plegia = both halves
A traumatic spinal cord injury is a lesion of neural elements of the spinal cord that can result in any degree of sensory and motor deficit, and autonomic or bowel dysfunction. What does paraplegia mean?
1 - loss of movement and sensation on one side of the body
2 - loss of movement and sensation in all limbs
3 - loss of movement and sensation in lower limbs
4 - loss of movement and sensation in upper limbs
3 - loss of movement and sensation in lower limbs
- paraplegia =
- para - is greek for paralysed
A traumatic spinal cord injury is a lesion of neural elements of the spinal cord that can result in any degree of sensory and motor deficit, and autonomic or bowel dysfunction. What does hemiplegia mean?
1 - loss of movement and sensation of limbs on one side of the body
2 - loss of movement and sensation in all limbs
3 - loss of movement and sensation in lower limbs
4 - loss of movement and sensation in upper limbs
1 - loss of movement and sensation of limbs on one side of the body
When assessing a patient with a suspected spinal cord injury, which of the ABCDE is most important?
- A for airway
- if cervical spine is damaged airway can be compromised
if damaged which vertebrae can be life threatening?
1 - C3, 4 and 5
2 - C1 and C2
3 - C3, 4 and T1
4 - C7, 8 and T1
1 - C3, 4 and 5
- the rhythm is C3, 4, 5 keeps the diaphragm alive
- above C5 requires intubation
In the event of a trauma, should we always presume a spinal cord injury?
- yes
- until proven otherwise
- use a rigid cervical collar
- use firm spinal board with lateral support
In a spinal cord injury we need to be careful not to cause decubitus. What is this?
1 - new fractures due to transport
2 - blood born infection
3 - pressure ulcers
3 - pressure ulcers
In a spinal cord injury we need to be careful not to cause decubitus, which are pressure ulcers from remaining on the hard spinal support immobilised. How long before decubitus form?
1 - 1-6 minutes
2 - 15-20 minutes
3 - 30-60 minutes
4 - >2 hours
3 - 30-60 minutes
Patients with a spinal fracture often have a second one elsewhere. What % of patients does this occur in?
1 - 1-5%
2 - 10-15%
3 - 30-40%
5 - >50%
2 - 10-15%
When we assess a patient for risk of a cervical spine injury, we need to use which system?
1 - CURB score
2 - Wells score
3 - Canadian C-spine
4 - Modified Glasgow Score
3 - Canadian C-spine
- Age - >65 high risk
- Mechanism (e.g. wearing seatbelt v ejection from vehicle)
- Abnormal neurological symptoms (paraesthesia or weakness or numbness)
- Ambulation
- Neck Pain
- Neck range of movement (in low risk group – don’t move neck in high risk group!)
