Spinal symposium Flashcards
State whether the cervical, thoracic and lumbar spine have kyphosis or lordosis
c and L = lordosis
T = kyphosis
|n what plane is the spine straight?
coronal
If the spine is not straight in coronal what does this mean?
scoliosis
3 erector spinae muscles
illiocostalis
longissimus
spinalis
Epidemiology of spinal cord injuries
1000/year in UK with most being male
20-29 years
50 000 in UK with paralysis
Causes of spinal cord injuries
falls - RTA - tumour - infection - sport
Complete SCI
no motor or sensory function distal to lesion
no anal squeeze, sacral sensation or chance of recovery
What ASIA grade is complete SCI?
A
Incomplete SCI
some function present below site of injury
more favourable prognosis
Why may you not be able to determine acutely if it is incomplete or complete SCI?
spinal shock
ASIA grade and description
A- complete, no sensory or motor in S4-5
B- incomplete, no motor in S4-5
C- incomplete, motor below level - muscles <3 power
D - incomplete, motor below level - muscles >3
E- normal sensory and motor
Quadriplegia/tetraplegia
partial or total loss of use of all 4 limbs and trunk
loss of motor/sensory function in cervical region
What happens in tetraplegia
cervical fracture - phrenic nerve (diaphragm)
resp failure and spasticity
spasticity in tetraplegia
increased muscle tone
UMN lesion - spinal cord and above
lesions above L1
Paraplegia
partial or total loss of use of lower limbs
Symptoms of paraplegia
impairment or loss of sensory/motor in T/L/S arm function spared possible impairment in trunk bladder/bowel function spasticity in spinal cord injured
aetiology of paraplegia
thoracic or lumbar fractures
associated chest or abdominal injuries
Central cord syndrome - briefly describe
older patients eg arthritic neck, hyperextension injury
arm>leg weakness, perianal sensation and lower extremity power preserved
low velocity fall
anterior cord syndrome - briefly describe
hyperflexion injury, anterior compression fracture
injured anterior spinal artery
anterior cord syndrome symptoms
profound weakness
fine touch and proprioception preserved
Causes of Brown-Sequard syndrome
penetrating injuries eg gunshot/stab wound
What is Brown-Sequard syndrome?
hemi-section of cord
symptoms in Brown-Sequard syndrome and tracts affected
paralysis on affected side - corticospinal
loss of proprioception and local fine discrimination - dorsal
pain and temp loss on opposite side below lesion - spinothalamic
Managing SCI - broad
prevent 2 insult
ABCD
ATLS
ABCD - explain
A - c spine control
B - ventilation, O2, associated chest injury
C - IV fluids, neurogenic shock? low BP and HR, vasopressors
D - neurological function, PR and perianal, log roll
Spinal shock
transient depression of cord function below injury level
flaccid paralysis and areflexia
several hours –> days
