  1. Why is it important to know skeletal trauma and surgical radiography terms?
    • Allows technologist to understand:
    •   which type of injury or fracture is suspected
    •   which projection to make
    •   how to avoid positioning that could cause pain or injury
  2. Dislocation / luxation
    • Bone is displaced from a joint
    • Movement of these parts could be painful and must be avoided
    • Get two projections, 90 degrees apart to show degree of separation
  3. If dislocated joint has relocated, are x-rays still necessary?
    • Yes.
    • Damage could have still occurred
    • Get two projections, 90 degrees apart
  4. Subluxation
    Partial dislocation
  5. Nursemaid's Elbow / Jerked Elbow
    • Partial dislocation of radial head of child's elbow, due to hand / wrist being sharply jerked by an adult.
    • Frequently reduced when forearm is supinated for AP elbow projection.
  6. Sprain
    Forced wrenching or twisting of a joint that results in a partial rupture or tearing of supporting ligaments, without dislocation.
  7. Possible damage caused by sprain
    • May result in severe damage to associated:
    •   blood vessels
    •   tendons
    •   ligaments
    •   nerves
  8. Contusion
    Bruise type of injury with possible avulsion fracture.
  9. Fracture
    A break in the bone.
  10. Positioning of possible fractures
    • Use caution when moving possible fractures parts
    • Never force a potentially fractured limb or body part into position
    • Adapt positioning as needed
  11. Apposition
    Describes the manner in which the fragmented ends of the bone make contact with each other.
  12. Anatomic apposition
    Ends of the broken fragments make end-to-end contact.
  13. Lack of apposition
    Ends of fragments are aligned but pulled apart and are not making contact with each other.
  14. Bayonet apposition
    • Fragments overlap and the shafts make contact, but not at the fracture ends.
    • (Bont. 573)
  15. Angulation
    • Loss of alignment of the fracture.
    • Long bone fragments at angles to each other.
  16. Apex Angulation
    Kind of like, if a straight bone is broken into a kind of sideways V shape.  If the point of the V points toward the midline of the body or away from midline of body.
  17. Varus deformity
    Break opens away from midline of the body, apex of the now broken bone points away from midline of the body.
  18. Valgus deformity
    Break opens toward midline of body, apex of now broken bone points towards midline of body.
  19. Simple / closed fracture
    Bone does not break through the skin.
