SPINAL INJURIES Flashcards
(45 cards)
What vital structures are at risk in neck trauma?
Airway, jugular vein, arteries, thyroid gland, parathyroid gland, and nerves.
What is the most common cause of death in penetrating neck trauma?
Haemorrhage.
What is a major concern in blunt neck trauma?
Airway damage, especially to the larynx.
What is a common spinal consequence of hanging?
Cervical spine disruption.
What are signs of laryngeal or tracheal injury?
Voice alterations, stridor, drooling, dyspnoea, and haemoptysis.
What effect can airway burns have?
Swelling that closes off the airway.
How many vertebrae are in each spinal section?
7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 3–4 fused coccygeal.
What is lordosis and kyphosis?
Lordosis is an inward curvature; kyphosis is an outward curvature.
What does the atlanto-occipital joint allow?
Nodding movement of the skull.
Where is the spinal canal narrowest and most vulnerable?
Sub-axial cervical spine (C3–C7).
Why is the thoracic spine less commonly injured?
Limited range of motion and protected by the rib cage.
Why is the thoracolumbar junction vulnerable?
Due to spinal curvature and load transfer.
What are the three main spinal ligaments?
Anterior longitudinal, posterior longitudinal, and ligamentum flavum.
What is the function of facet capsules?
Prevent facet joints from separating.
What is the butterfly-shaped region in spinal cord cross-section?
Grey matter (cell bodies).
What is the function of dorsal and ventral roots?
Dorsal root: afferent (sensory); ventral root: efferent (motor).
What are the common mechanisms of spinal column injury?
Falls, collisions, transport accidents, water-related incidents.
What can spinal column injury involve?
Fracture, subluxation, or dislocation with or without damage to discs, ligaments, or facet joints.
What distinguishes spinal cord injury from spinal column injury?
SCI causes neurological damage; spinal column injury may not.
What defines a complete SCI?
Complete disruption of spinal tracts, causing tetraplegia or paraplegia.
What characterizes an incomplete SCI?
Partial motor or sensory function remains; may improve or worsen.
What are mechanisms of spinal injury?
Axial compression, flexion-compression, extension, distraction, rotation.
What is a Jefferson’s fracture?
C1 ring fracture due to axial compression; stable unless ligaments rupture.
What region is most vulnerable to flexion-compression injuries?
C4–C6.
