Measurements (Normal)
- Post vert > ant vert + 3mm
- Predental space < 3mm
- < 5mm in children
- Spinal canal narrowest point should be >13mm (lateral)
- Anterior Soft tissue
- at C1-C4 < 7mm
- at C5-T1 < 22mm
PEDS
- Children <8yo
- ~50% SCI have no x-ray changes
- most higher than C3
- Pseudosubluxation (peds) = C2 on C3 posterior cervical line (nl = <2mm)
Lateral
Alignment: Anterior, posterior, middle arcs
Bones: Vertebrae and spinous processes uniformity and height
Cartilage:intervertebral disc space height and length
Soft tissue: prevertebral soft tissue width
