  2. list the order of carpal development
  3. recite in order both the proximal and distal rows of carpal bones
  4. describe ulnar variance
  5. list the bones that align longitudinally in a laterally neutral wrist image
  6. specify the amount of space between the scaphoid and lunate in a mature carpus
  7. explain where buckle fractures most commonly occur in the pediatric wrist
  8. list views that are helpful in identifying subtle wrist injuries
  9. state radiographic findings that indicate further evaluation of occult type 1 fractures
  10. list the Salter-Harris fracture classification types
  11. note the prevalence of Galeazzi fractures
  12. identify which imaging modality detects bone contusion
  13. specify the modalities that best demonstrate pediatric lunate injuries
  14. describe how capitate fractures occur
  15. verbalize the key finding on lateral wrist radiographs that helps diagnose carpal dislocation
