neurology case study KANIS Flashcards
which spinal level is most associated with herniated disk?
lumb disk disease spinal level association
L5
L4-L5, or L5-S1
What does S1 spinal nerve reflex goes to?
gastrocnemius/soleus- of the ANKLE
so damage to S1 can cause abnormality to ankle
what is the most common cause of chronic or recurrent low back or leg pain?
lumbar disk disease
what causes the Pain for Lumbar disk disease
nerve root injury due to compression, inflammation, or both
what are the 4 indications for intervertebral disk surgery?
Progressive motor weakness from nerve root injury
Bowel or bladder disturbance**huge red flag
Incapacitating nerve root pain despite conservative tx for at least 4 weeks
Recurrent incapacitating pain DESPITE conservative tx
these are 4 indications that indicates surgical tx
what causes the pain down the leg?
-lumbar disk rupturing causing compression on nerve: herniated disk or disk disease***
-lumbar spinal stenosis :narrowed spinal canal**
(top 2 are the two main ones)
- Herpes zoster
- Facet hypertrophy
Shingles
sensory neuritis due to infection with varicella zoster virus
what can statin induce?
myalgia; anyone at anytime could develop myopathy while taking statin
what is the disease with unilateral symptoms or signs due to to bony compression and may be indistinguishable from disk related radiculopathy
Facet hypertrophy
L5 nerve room reflex/sensory/motor/pain
Reflex: none
sensory: dorsal surface of foot and lateral calf
motor: foot eversion,dorsiflexion, hip adduction, toe dorsiflexion
Pain: lateral calf, dorsal foot, posterolateral thigh, butt
S1 nerve room reflex/sensory/motr/pain
reflex: gastroc/soleus-ANKLE
sensory: plantar and lateral surface of foot
Motor: plantarfexion, toe flexor, hip extenson
pain:plantar foot, posterior calf, posterior thigh and buttocks
what spinal levels are associated with peroneal nerve damage? what is the key presentation of damage?
L4-S1
Drop foot (loss of dorsiflexors)
