Flashcards in Spinal cord compression Deck (22)
What can cause acute spinal cord compression?
Tumours; hemorrhage or collapse
What can cause chronic spinal cord compression?
Degenerative disease - spondylosis
What is a complete cord transection?
All motor and sensory modalities affected; sensory and motor level
Will patients show an UMN lesion as soon as the cord is transected?
No; initially a flaccid areflexic paralysis
UMN appears later
What is brown-sequard syndrome show?
Ipsilateral motor level
Ipsilateral dorsal column sensory level
Contralateral spinothalamic sensory level
What mechanism can result in central cord syndrome?
Hyper Flexion or extension injury to already stenotic neck
What will be the distribution of central cord syndrome?
Distal upper limb weakness
Cape-like spinothalamic sensory loss
Lower limb power preserved
Dorsal columns preserved
What is the presentation of chronic spinal cord compression?
UMN signs predominate
What can cause spinal cord compression?
High energy trauma
What are the types of extradural tumours of the spinal cord?
Mets; lung, breast, kidney, prostate
What are the types of intradural tumours of the spinal cord?
Extramedullary; meningioma, schwannoma
Intramedullary; astrocytome, ependymoma
What will tumours do to the spinal cord?
Can also cause acute compression by collapse or haemorrhage
What is spinal canal stenosis?
Bulging of IV discs
Facet joint hypertrophy
What infections can affect the spinal cord?
Epidural; bloodborne, staph, TB
Surgery or trauma
What types of haemorrhage can cause spinal cord compression?
What are risk factors for haemorrhage in the spinal cord?
What are the treatment options for traumatic spinal compression?
Decompress and stabilise; surgery, traction, external fixation
What is the treatment for metastatic tumours causing spinal compression?
IV dexamethasone THEN investigate; radiotherapy, chemotherapy
Surgical decompression and stabilisation - ONLY if appropriate
What is the treatment for primary spinal cord tumours?
Tx for infection of the spinal canal?
Stabilisation if osteomyelitis occured
Tx for hemorrhage
