Q

What distinguishes spinal cord injury from spinal column injury?

A

SCI causes neurological damage; spinal column injury may not.

20
Q

What defines a complete SCI?

A

Complete disruption of spinal tracts, causing tetraplegia or paraplegia.

21
Q

What characterizes an incomplete SCI?

A

Partial motor or sensory function remains; may improve or worsen.

22
Q

What are mechanisms of spinal injury?

A

Axial compression, flexion-compression, extension, distraction, rotation.

23
Q

What is a Jefferson’s fracture?

A

C1 ring fracture due to axial compression; stable unless ligaments rupture.

24
Q

What region is most vulnerable to flexion-compression injuries?

25
What is a teardrop fracture and how is it caused?
Extension injury causing anterior ligament tension and vertebral fracture.
26
What is a hangman’s fracture?
Traumatic spondylolisthesis of C2; unstable with low SCI risk.
27
What is atlanto-occipital dislocation?
Detachment of the skull from the spine; high mortality.
28
What is SCIWORA?
Spinal Cord Injury Without Radiological Abnormality; common in children.
29
Why are children more prone to SCIWORA?
Softer vertebrae, flatter facet joints, larger head-to-body ratio.
30
What spine issues are more common in elderly patients?
Disk degeneration, osteoporosis, instability, face-first falls.
31
What signs suggest spinal cord injury?
Paralysis, paraesthesia, low HR/BP, flushed skin, paradoxical breathing.
32
What is priapism and what does it indicate in spinal injury?
Prolonged erection without stimulation; can indicate SCI.
33
How do you clear a patient from spinal immobilisation in the field?
GCS 15, no altered behaviour, no neck/head/shoulder pain, no neurological symptoms, no distracting injuries.
34
What devices are used for spinal immobilisation?
C-collar, vacuum mattress, spinal board (for transport), manual in-line immobilisation, spinal extrication splint.
35
When should spinal immobilisation be used?
With trauma history, unconscious patients, or signs of neurological injury.
36
What is the purpose of a cervical collar?
Physically limits neck movement in trauma patients.
37
What is the purpose of a log roll?
To assess the back with synchronised movements.
38
When is a spinal extrication splint appropriate?
In non-time-critical patients with suspected spinal column injury.
39
What are benefits of a vacuum mattress?
Comfortable, reduces pressure sore risk, good spinal support.
40
When is manual in-line immobilisation used?
In time-critical patients to stabilise the neck.
41
How is a helmet removed safely in spinal injury?
Two-person technique with manual stabilisation and gentle removal.
42
What factors may contraindicate spinal immobilisation?
Significant kyphosis, time criticality, lack of neurological symptoms, and clear conscious state.
43
What must be reported in spinal injury cases?
Mechanism of injury, force vector, extraction and immobilisation methods, neurological deficits.
44
What is the controversy around spinal boards and clearance?
USA uses time-consuming tie-down methods; Europe prefers vacuum mattress and questions spinal boards' benefits.
45
Describe the functional anatomy of the spinal cord and the significance of dorsal and ventral roots.
The spinal cord contains grey matter (central, H-shaped) for cell bodies and white matter for nerve tracts. ## Footnote Dorsal root: Afferent (sensory) input. Ventral root: Efferent (motor) output. Damage to these roots impairs sensory or motor function, depending on location and severity.
