Question 4

this measurement in the c-spine is a relative contraindication to elective ortho surgery

Answer 4

an ADI more than 7-10 mm or a posterior space less than 13mm

Question 5

in the cervical spine the numbered root exits

Answer 5

in this region of the spine the nerve root exits above it’s numbered pedicle

Question 6

in the lumbar spine the numbered root exits

Answer 6

in this region of the spine the nerve root exits below it’s numbered pedicle

Question 7

this spinal cord injury carries the worst prognosis

Answer 7

what is significant about anterior cord syndrome

Question 8

this spinal cord injury is the most common

Answer 8

what is significant about central cord syndrome

Question 9

this spinal cord injury carries the best prognosis

Answer 9

what is significant about Brown-Sequard syndrome

Question 10

a far lateral disc in the lumbar affects this nerve root

Answer 10

in the lumbar spine the exiting nerve root is hit by a

Question 11

a central disc in the lumbar spine affects this nerve root

Answer 11

in the lumbar spine the traversing nerve root is hit by a

Question 12

in the cervical spine the exiting nerve root is hit by a

Answer 12

in this portion of the spine the nerve roots are more horizontal and any disc hits the exiting root

Question 13

reflex at c5

Answer 13

level of biceps reflex

Question 14

reflex at c6

Answer 14

level of brachioradialis reflex

Question 15

reflex at c7

Answer 15

level of triceps reflex

Question 16

reflex at c8

Answer 16

ha! got ‘eem! no reflexes here! but this does finger flexion

Question 17

reflex at T1

Answer 17

ha! got ‘eem! no reflexes here! but this does the interossei

Question 18

reflex at L4

Answer 18

level of patellar reflex

Question 19

reflex at L5

Answer 19

ha! got ‘eem! no reflexes here! but this does the toe extensors

Question 20

reflex at S1

Answer 20

level of the achille’s reflex

Question 21

the safe interval between the spinous process and the vertebral artery typically is

Answer 21

2cm with respect to the posterior spinal approach

Question 22

injury to the stellate ganglion and therefore Horner’s syndrome can be avoided by this technique when doing anterior cervical spinal surgery

Answer 22

this is avoided by dissecting the longus colli subperiosteally in anterior cervical surgery

Question 23

this palsy is most common after posterior spinal surgery

Answer 23

why your postop spine pt has deltoid weakness and decreased biceps reflex, i.e. C5 palsy

Question 24

at what level do the great vessels bifurcate

Answer 24

why a larger dissection is needed at the L4-5 level in comparison to the L5-S1 level when performing retroperitoneal lumbar spine approach
