1. MCQ + 3D Model
Topic: Cervical Spine (Lateral Projection)
Stem:
"Which structure must align with the anterior margin of the mandibular ramus for
a true lateral C-spine?"
a) C1 anterior arch
b) Odontoid process
c) C7 spinous process
d) Hyoid bone
Correct Answer: a) C1 anterior arch
Explanation:
The anterior arch of C1 must align with the mandibular ramus to ensure
proper positioning. This prevents superimposition of the mandible over the
upper cervical vertebrae. Misalignment can obscure critical structures like the
odontoid process.
Added Value:
• 3D Model Link: Rotate a cervical spine model to visualize C1 alignment.
• Reference: Bontrager p. 450.

2. Trauma Case Study + AR Demo
Topic: Jefferson Fracture
Stem:
"A patient post-MVA has prevertebral swelling on lateral C-spine. Which
projection confirms a Jefferson fracture?"
a) Open-mouth odontoid
b) AP axial (Towne)
c) Oblique cervical
d) Swimmer’s view
Correct Answer: a) Open-mouth odontoid
Explanation:
Jefferson fractures involve burst fractures of the C1 ring. The open-mouth
odontoid view shows lateral displacement of the C1 lateral masses relative to
the dens. Prevertebral swelling on lateral view is a red flag for underlying
fracture.
Added Value:
• AR Simulation: Adjust CR angles to profile C1-C2 in AR.
• Clinical Tip: "Bilateral C1 lateral mass displacement >7 mm indicates
instability (Bontrager p. 465)."

3. Pathology-Based MCQ
Topic: Lumbar Disc Herniation
Stem:
*"Which MRI finding correlates with L4-L5 disc herniation compressing the L5
nerve root?"*
a) Posterolateral disc extrusion
b) Central protrusion
c) Facet hypertrophy
d) Ligamentum flavum thickening
Correct Answer: a) Posterolateral disc extrusion
Explanation:
The L5 nerve root exits below the L4-L5 disc. A posterolateral herniation at this
level compresses the traversing L5 root, causing radiculopathy (e.g., sciatica).
Central protrusions compress the cauda equina.
Added Value:
• Image Slider: Compare MRI axial views of herniation vs. normal.
• Key Insight: "L5 compression = pain radiating to the dorsum of the foot
(p. 480)."
