a fractuure which both cortices of bone have been disrupted.

• a fracture that involves only one cortex of bone
• commone in kids

• 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

• 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

• "simple"
• factures is covered by intact skin

muscle rips off the bone

• "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)

fracture that has more than 2 fracture fragments

• in long bones
• suggestive of pathology

common in long bones

more common in small bones

• suggests a rotatiional mechanism of injury
• if see clean fratures in multiple views

avulsed, impacted and distracted

• a ligamentous of tendinous insertion site
• the frament is pulled away fromt he parent bone

• forces produce a compression of bone
• impaction of trabeculae on each other
• look for a white zone of condensation

fracture framents areheld apart by interposed soft tissues or muscle pull

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

• fatigue fracture
• insufficiency fracture

they creep up on you ie. from running

• a fracture produced by abnormal stress of NORMAL bone
• athletes

a fracture produced by normal stress on ABNORMAL bone ie. osteoporosis

comminuted fracure of a vertebral body produced by an axial load on a neutral spine

fracture fragments displace anteriorly and posteriorly

UNSTABLE

associated with injury to the spinal cord

• T1- fat bright
• T2 - H2O bright

for fractures get a ster image b/c fracture will light up

• assessed with spinal injuries
• potential for injury to the spinal cord
• many different differing opinions
• if unstable you'll probably need to refer out

• 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)

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
