avulsion fractures
How far apart are the joint spaced in the wrists in adults?
1-2 mm wide
What are narrow joint spaces in the wrist probably due to?
Probably artifacts from projection or degenerative changes
What is the worst classification of Salter Harris?

What is a type I Salter Harris injury?
An injury to the growth plate
What is a helpful modality for hip fractures?
MRI
What is a type III Salter Harris injury ?
Through epiphysis that goes through into the epiphyseal plate.

Fluid fat level
What movement causes a Weber A injury?
Inversion
What movement causes a Weber B injury?
Eversion
What is the fracture name for when there is an oblique fracture of the distal fibula (usually hear a snap)?
Weber B
What is the fracture name when you have an avulsion fragment straight across the fibula due to a tug?
Weber A
Describe the fracture: straight line, 90° to longitudinal axis
transverse fracture
due to rotational force - S-shape
Spiral fracture
along bone length
longitudinal fracture
rotational force - doesn’t circulate around bone
oblique fracture
> 1 fracture line, > 2 bone fragments
comminuted fracture
telescoping of fragment into another
impacted fracture
incomplete with intact cortical side flexed
greenstick fracture
failure of one cortical surface
stress fracture
separation at site of attachment of ligament or tendon
avulsion fracture
ends of fracture are separated
displaced fracture
fragments remain in alignment & position
non-displaced fracture
fragment displaced below level of surface of bone
depressed fracture
disrupts continuity through whole bone
complete fracture
cortex buckles/cracks - no loss of continuity
incomplete fracture
bone exposed outside integument
open fracture
bone contained inside integument
closed fracture
displacement of bone from normal - articulating surfaces lose contact
dislocation
displacement - articulating surfaces partially lose contact
subluxation
