Top Ten principles of setting fx

A

  2. xrays in two planes
  3. look for an injury in another bone
  4. correct a both angular and rotational misalignment
  5. take stress xrays
  6. Do not be satisfied with one dx (always look for another injury.
  7. Reduce the fx ASAP
  8. evaluate for joint instability and tendon function
  9. usefulness of extremity (not just xray)
  10. Irreducibility may signify soft tissue interposition

68
Q

Principles of treatment, fracture in children

A
  1. Mild angular deformities in the plane of motion frequently correct themselves with growth
  2. rational misalignment does not currect itself
  3. apposition and mild shortening are of less importance in young children
  4. remodeling is greater when fractures closer to the physis.
  5. physical therapy after the fracture has headled is usually unnecessary and may even be unwise.
  6. A tender growth plate after an inury usually means that a fracture is present, even though a fracture may not be apparent on x-ray.
  7. nonunion is almost impossible in children
  8. malposition may not be correctable after 7-10 days.
