  1. complete fracture
    a fractuure which both cortices of bone have been disrupted.
  2. incomplete fracture
    • a fracture that involves only one cortex of bone
    • commone in kids
  3. greenstick fracture
    • incomplete fracture of the long bones of extremities
    • seen only in kids
    • bone bows out so you know theres a fracture but you can't see it
  4. torus fracture
    • incomplete fracture of the long bones of extremitiesseen only in kids
    • bulge (looks like a roman pillar) it's typticaly only in one spot
    • because of that you have to look at all views
    • primary location is distal radius
  5. closed fracture
    • "simple"
    • factures is covered by intact skin
  6. emulsion fracture
    muscle rips off the bone
  7. open fracture
    • "compound"
    • is not covered by intact skin
    • there is communication between the fracture and the outside enviornment
    • it is suscepticble to infection (toes and fingers)
  8. comminute fracture
    fracture that has more than 2 fracture fragments
  9. transvers fracture
    • in long bones
    • suggestive of pathology
  10. oblique fractre
    common in long bones
  11. vertical fracture
    more common in small bones
  12. spiral
    • suggests a rotatiional mechanism of injury
    • if see clean fratures in multiple views
  13. displacement of fracutre fragments
    avulsed, impacted and distracted
  14. aculsed fracture
    • a ligamentous of tendinous insertion site
    • the frament is pulled away fromt he parent bone
  15. impacted
    • forces produce a compression of bone
    • impaction of trabeculae on each other
    • look for a white zone of condensation
  16. distracted
    fracture framents areheld apart by interposed soft tissues or muscle pull
  17. apposition
    how are the 2 fracture ends doing? do the need to be pinned or are they alligned?

    typically let kids be even if bad apposition bc the bones will still grow back together
  18. stress fracture
    • fatigue fracture
    • insufficiency fracture

    they creep up on you ie. from running
  19. fatigue fracture
    • a fracture produced by abnormal stress of NORMAL bone
    • athletes
  20. insufficiency fracture
    a fracture produced by normal stress on ABNORMAL bone ie. osteoporosis
  21. burst fracture
    comminuted fracure of a vertebral body produced by an axial load on a neutral spine

    fracture fragments displace anteriorly and posteriorly


    associated with injury to the spinal cord
  22. T1 vs T2 mri
    • T1- fat bright
    • T2 - H2O bright

    for fractures get a ster image b/c fracture will light up
  23. stability vs instability
    • assessed with spinal injuries
    • potential for injury to the spinal cord
    • many different differing opinions
    • if unstable you'll probably need to refer out
  24. three columns of the spine
    • anterior: ALL and ant 2/3 of vert body and disc
    • middle: PLL and post 1/3 body and disc
    • posterior: post arch and ligaments (pedicle, TPs, laminae, articular facets, SPs)
  25. rule with 3 columns and stability
    injuries involving one column are likely to be stable

    injuries involving 2 or 3 are likely to be unstable and will likely result in neurologic injury
