Reading Pediatric Ortho Films Flashcards
Where growth occurs. Caps the metaphysis and supports articular cartilage. Blood supply may be limited
Epiphysis
Portion of the bone converted from cartilage until remodeled to diaphysis. Active metabolic area with formation of blood elements. End-arterial loops susceptible to embolic phenomena
Metaphysis
Thick, central bone that serves a supporting function. Cortical and cancellous bone
Diaphysis
How many planes do you need for fracture films?
2 (at least AP and lateral)
How do you distinguish between fracture and accessory bone?
accessory bones have smoother surfaces and total mass greater than expected
Common fractures for peds because their bones are soft
greenstick, torus, curved
Why are fractures hard to see in kids?
have sturdy periosteum
Differences between treatment for adult and children fractures
Kids heal quickly, can remodel so they are usually treated conservatively
A transverse fracture through the growth plate according to salter-harris classification
type I
A fracture through the growth plate and the metaphysis, sparing the epiphysis. according to salter-harris classification
type II
A fracture through growth plate and epiphysis, sparing the metaphysis according to salter-harris classification
type III
A fracture through all three elements of the bone, the growth plate, metaphysis, and epiphysis according to Salter-harris classification
type IV
A compression fracture of the growth plate (crush injury) according to salter-harris
type V
Pattern seen with osteosarcoma
sunburst
Pattern seen with Ewing’s sarcoma
