Spinal Fractures and Cord Injuries Flashcards
C- spine injuries investigations
X-ray
- AP, lateral, odontoid peg open mouth view
CT scan
C-spine injuries consequences
Can be fatal if above C3
C-spine injuries treatment
Stable C-spine injuries
- Firm cervical collar
Unstable. C-spine injuries
- Halovest
Insufficiency Wedge fractures epidemiology
Elderly
- With osteoporosis
Chance Fractures aetiology
High energy flexion-distraction injury occurring in the thoracic region
Involve failure. of the posterior ligaments in the spine
Chance fractures: indications for surgery in thoracolumbar spine
Neurological deficit
Unstable injury
Chance Fractures: Surgery Options
Pedicle screws and rods
Spinal fusion
Spinal decompression (if neurological deficit)
Secondary damage to spinal cord aetiology
Vascular disruption
Hypotension
Hypoxia
Inflammatory response
Spinal shock
Sensation, motor function and reflexes are lost below level of injury
Usually resolves after 24 hours
Bulbocavernous reflex is lost (contraction of anal sphincter)
Treatment of neurogenic shock
IV fluid therapy
Complete Spinal Cord Injury
No sensory or motor function remains below injury level
Incomplete Spinal Cord Injury
Some neurological function remains below the level of trauma
If there is loss of motor function from T1-T12 then ventilatory support may be needed for patient to survive
Central Cord Syndrome
Commonest injury pattern of the spine
Central Cord Syndrome Aetiology
Hyperextension injury in cervical spine
OA in spine
Central Cord Syndrome signs
Paralysed arms
- Corticospinal motor tracts of the upper limbs are more central in the cord
Central Cord syndrome results in loss of…
Loss of
- motor function
- Coarse touch
- temperature sensation
Central cord syndrome functions preserved
Proprioception
Vibration sense
Light touch
Posterior Cord Syndrome
Rare
Posterior cord syndrome results in loss of…
Loss of
- dorsal column function
- proprioception
- Vibration sense
- Light touch
Brown-Sequard Syndrome
Damage to one half of spinal cord
Brown-Sequard Syndrome Aetiology
hemisection of the spinal cord from a penetrating injury
Brown-Sequard Syndrome consequences
paralysis of ipsilateral side of spinal cord
Brown Sequared Syndrome results in loss of…
Dorsal column function
Contralateral sense of pain, coarse touch and temperature sensation
(nerve fibres of spinothalmic tracts cross to the contralateral side 1-2 levels above their entry to the cord.
