Checklist

# Keep everything in one place

Position

(if possible, in side-by-side comparison!):

  • Axial?
  • Symmetrical?
  • Front and rear alignment (spine) correct?
Bones

(if possible, in side comparison!):

  • Size and shape (normal proportion)?
  • Structure (mineral content, cancellous bone)?
  • Contour (cortical smooth, contour interruption, step formation, sclerosis, erosions)?
  • Width of the compacta? - Periosteal appositions, periosteal detachment - epiphyseal joints (open, closed)?
  • Circumscribed lightening or densification? - Medullary canal width - Usures on the ribs?
Joints

(if possible, in lateral comparison!):

  • Shape (normal proportions, congruence of articular surfaces)?
  • Contour (cortical bone smooth and intact, spondylophytic - or osteophytic protrusions, (subchondral) sclerosis, (subchondral) erosions, (subcortical) cystic lightening)?
  •  Widening of the joint space?
  •  Ankylosis?
  •  Intraarticular bone fragments?
  •  Accessory bones?
  •  Periosteal appositions, periosteal detachment?
Soft tissues

(if possible, in side comparison!):

  • Swelling?
  • Foreign body?
  • Calcifications (intra- or periarticular calcifications, vascular calcifications, tendon attachment calcifications?
  • Fat pad sign (e.g. after elbow lesion)
  • Vacuum phenomenon (in the intervertebral space)?
