WEEK 8 SCI Flashcards
(23 cards)
What is the global prevalence of spinal cord injury (SCI)?
Over 15 million people are living with SCI globally
WHO, 2024
How many people with SCI are living in the UK?
Approximately 105,000 people
SIA 2024
What are the yearly new cases of SCI in the UK?
Approx. 4,400 individuals
SIA 2024
What demographic was previously predominant in SCI cases?
Young, male individuals with a 1.5: 1 male to female ratio
What are the three mechanisms of traumatic SCI?
- Destruction from direct trauma
- Compression by bone fragment, hematoma, or disc material
- Ischemia from damage or impingement on the spinal arteries
What is the leading cause of SCI in the UK?
Falls (40%) followed by road traffic accidents (RTA) at 37%
Define complete SCI.
Complete loss of function below the injury including motor, sensory, and autonomic dysfunction
What is incomplete SCI?
Some sparing of neural activity below the level of the lesion
What are the four main types of incomplete SCI?
- Central cord syndrome
- Anterior cord syndrome
- Brown-Sequard syndrome
- Posterior cord syndrome
What is tetraplegia?
Impairment at cervical segments affecting all four limbs
What is paraplegia?
Impairment at thoracic, lumbar, or sacral segments involving lower limbs
What are the vulnerable areas of the vertebral column for SCI?
- Cervical spine, typically C5-7
- Thoracolumbar, typically T12
What characterizes central cord syndrome?
Motor dysfunction in upper limbs and bladder dysfunction
What is the effect of Brown-Sequard syndrome?
Motor deficit and numbness to touch and vibration on the same side, loss of pain and temperature sensation on the opposite side
What is posterior cord syndrome?
Sensory disturbance with less motor loss due to compression of the posterior/sensory section of the spinal cord
What is cauda equina syndrome?
Lower motor neuron lesion with motor and sensory loss in lower limbs and saddle anaesthesia
What is the immediate medical management following trauma in SCI?
Stabilisation, ensuring normal oxygenation, perfusion, and acid/base balance
What complications must be managed post-acute SCI?
- Urinary and bowel management
- Skin integrity (pressure sores)
- DVT
- Autonomic dysreflexia
- Orthostatic hypotension
What is the ASIA classification used for?
To define the level of injury based on the first spinal segmental level showing abnormal neurological loss
What differentiates anterior cord syndrome?
Motor paralysis below the lesion, loss of pain and temperature sense, retained proprioception and vibration
What are some examples of other pathologies leading to sensorimotor loss?
- Stroke
- Multiple sclerosis
- Guillain-Barré syndrome
- Transverse myelitis
- Myasthenia gravis
- Botulism
- Hypoglycemia
- Diabetic neuropathy
What is the role of a thorough clinical assessment in SCI diagnosis?
Essential for differentiating SCI from other pathologies with similar presentations
Fill in the blank: The ASIA Impairment Scale is used for ______.
[classifying the severity of spinal cord injuries]
