Q

reflex at c7

A

level of triceps reflex

17
Q

reflex at c8

A

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

18
Q

reflex at T1

A

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

19
Q

reflex at L4

A

level of patellar reflex

20
Q

reflex at L5

A

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

21
Q

reflex at S1

A

level of the achille’s reflex

22
Q

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

A

2cm with respect to the posterior spinal approach

23
Q

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

A

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

24
Q

this palsy is most common after posterior spinal surgery

A

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

25
Q

at what level do the great vessels bifurcate

A

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