Flashcards in Reading Pediatric Ortho Films Deck (17):
1

Where growth occurs. Caps the metaphysis and supports articular cartilage. Blood supply may be limited

Epiphysis

2

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

3

Thick, central bone that serves a supporting function. Cortical and cancellous bone

Diaphysis

4

How many planes do you need for fracture films?

2 (at least AP and lateral)

5

How do you distinguish between fracture and accessory bone?

accessory bones have smoother surfaces and total mass greater than expected

6

Common fractures for peds because their bones are soft

greenstick, torus, curved

7

Why are fractures hard to see in kids?

have sturdy periosteum

8

Differences between treatment for adult and children fractures

Kids heal quickly, can remodel so they are usually treated conservatively

9

A transverse fracture through the growth plate according to salter-harris classification

type I

10

A fracture through the growth plate and the metaphysis, sparing the epiphysis. according to salter-harris classification

type II

11

A fracture through growth plate and epiphysis, sparing the metaphysis according to salter-harris classification

type III

12

A fracture through all three elements of the bone, the growth plate, metaphysis, and epiphysis according to Salter-harris classification

type IV

13

A compression fracture of the growth plate (crush injury) according to salter-harris

type V

14

Pattern seen with osteosarcoma

sunburst

15

Pattern seen with Ewing's sarcoma

onion skinning

16

sign of trauma in the joint

fat pad sign (darkened area)

17

What are you worried about with a displaced salter I fracture?

premature closure of central growth plate--->growth arrest
