assessment of spinal cord 3 = 10 spinal cord syndromes Flashcards
spinal shock
complete transection
tracts affected?
deficits?
acute?
3-4 months?
all tracts
deficits = sensory and motor levels below lesion and root signs at site
acute = LMN signs + absent autonomic (bladder sweat)
3-4 moths = UMN + babinski
deficits = sensory and motor levels below lesion and root signs at site
acute = LMN signs + absent autonomic (bladder sweat)
3-4 moths = UMN + babinski
spinal shock
central lesions
causes?
syringomyelia
ependymoma
cord contusion
central lesions
tracts affected?
deficits?
anterolateral (pain/temp)
deficit = pain temp loss at level of lesion, sparing position
cape like distribution if in C-spine
deficit = pain temp loss at level of lesion, sparing position
cape like distribution if in C-spine
central lesions
posterior column syndrome
causes?
tabes dorsalis = neurosyphilis
posterior column syndrome
tracts
deficits
PCML
b/l loss of pain and vibration sense
b/l loss of pain and vibration sense
posterior column syndrome
combined anterior horn cell-pyramidal tract syndrome
causes
als
combined anterior horn cell-pyramidal tract syndrome
tracts
deficits
corticospinal tract
LMN cells in cord (motor)
loss of bilateral strength
loss of bilateral strength
combined anterior horn cell-pyramidal tract syndrome
brown-sequard
causes
compression by herniated discs, tumor, extramedullary absces
brown-sequard
tracts
deficits
crossed spinothalamic tract
Uncrossed PCML
crossed corticospinal tract
below lesion = loss of contralat pain/temp, ipsil touch/prop, ipsil strength
below lesion = loss of contralat pain/temp, ipsil touch/prop, ipsil strength
brown-sequard
posterolateral cord syndrome
cause
b12 deficiency = subacute combined degeneration
posterolateral cord syndrome
tracts
deficits
tracts = PCML and corticospinal
deficits =
b/l loss of position, vibration, strength
b/l loss of position, vibration, strength
posterolateral cord syndrome
anterior horn cell syndrome
causes
spinal muscular atrophy
poliovirus
anterior horn cell syndrome
tracts
deficits
no tracts
just LMNs
b/l loss of strength
b/l loss of strength
anterior horn cell syndrome
anterior spinal artery occlusion
tracts
deficits
spinothalamic and corticospinal
b/l loss of strength, pain, temp
sparing of position sense
b/l loss of strength, pain, temp
sparing of position sense
anterior spinal artery occlusion
pyramidal tract syndrome
causes
primary lateral sclerosis
pyramidal tract syndrome
tracts
deficits
corticospinal tracts
b/l UMN weakness with spastic gait
incr DTR
complete sparing of all sensory tracts and bladder function
b/l UMN weakness with spastic gait
incr DTR
complete sparing of all sensory tracts and bladder function
pyramidal tract syndrome
myelopathy with radiculopathy
causes
cervical spinal stenosis (congential or degenrative)
myelopathy with radiculopathy
tracts
deficits
any of all 3 tracts esp corticospinal
b/l UMN syndrome with spastic gait, incr DTR
ipsil or contralat root signs
possible bladder dysfunction
b/l UMN syndrome with spastic gait, incr DTR
ipsil or contralat root signs
possible bladder dysfunction
myelopathy with radiculopathy
