1

at what level do the majority of spinal injuries occur

C6/7

2

at what level do the majority of spinal injuries occur in children

C1/2

3

what are some possible causes of complete cord transections

trauma, infection, abscess, tumour

4

what is the presentation of a complete cord transection

loss of all modalities/sensation below the lesion
loss of motor function below the lesion

5

why do patients experience hypotension in a complete cord transection

loss of sympathetic input therefore vasodilation occurs via the parasympathetics

6

what are some causes of brown-sequard syndrome

penetrating trauma, fractured vertebrae, tumour, abscess, MS

7

what is the presentation in brown-sequard syndrome

ipsilateral loss of motor function and dorsal column modalities
contralateral loss of spinothalamic modalities

8

what are some causes of anterior cord syndrome

hyeprflexion injures leading to fractured vertebrae, anterior spinal artery injury

9

what is the presentation of anterior cord syndrome

loss of motor function below the lesion
loss of spinothalamic modalities below the lesion
preserve dorsal column modalities

10

what are the causes of central cord syndrome

hyperextension in the elderly
hyeprflexion in younger patients
syringomyelia
tumours
cervical spine stenosis

11

what is syringomyelia

development of a cyst in the central cord

12

what is the presentation of central cord syndrome

loss of motor and sensory in cape like distribution
upper extremities are affected more than lower extremities

13

what are some causes of posterior cord syndrome

spondylosis, infections, vit B12 deficiency

14

what is the presentation of posterior cord syndrome

loss of dorsal column modalities
preservation of corticospinal and spinothalamic tracts
