alignment of cervical spine – see below Bony changes:
vertebral body height
bone contour – trace around each vertebra individually – look for fractures, osteophytes.
decreased density (rheumatoid arthritis, osteoporosis, osteomalacia, metastatic osteolytic lesions) - weak points that are apt to succumb under stress.
increased density (acute compression fractures of vertebral bodies, metastatic osteoblastic lesions).
Cartilages – are intervertebral disc space margins parallel?; slight anterior or posterior widening of intervertebral space (or interspinous spaces) may be only clue to unstable dislocation.
Soft tissues (mainly in lateral cervical view – see below)
