Radiology Lecture Flashcards
To evaluate the area where the humerus and glenoid make contact, an x-ray is taken with the patient ______________.
abducting their arm; this allows for evaluation of fractures of the glenoid
Images are often taken with the hand deviated in the ulnar direction to assess ______________.
scaphoid fracture
True or false: the metaphysis is the growth plate.
False.
The physis is the growth plate. The metaphysis is between the diaphysis and the physis.
Describe the naming system for fractures.
When describing a fracture, describe where the distal fragment is in relation to the proximal fragment. Imagine the patient in the anatomical position when doing so.
CT evaluations of bone are good at assessing _______________.
abnormalities of bony geometry
Ultrasound is great at _______________.
analyzing soft tissue near the surface of the skin (such as injury to the Achilles tendon)
Nuclear medicine specifically refers to ___________.
PET scans
_____________-type injuries can lead to fractures of the scaphoid.
FOOSH
What is the “classic” shoulder injury that occurs in seizures and electrocutions?
Posterior dislocation
Differentiate the terms displacement and angulation?
Displacement refers to a movement of bone that moves two pieces apart in space. Angulation refers to pieces that may be in contact but are angled out of their anatomic plane.
A boxer’s fracture is _______________.
a fracture of the distal tip of the fifth metacarpal
In response to supraphysiologic stress, the cortex of the bone ________________.
becomes more sclerotic; if the excess stress continues, then a stress fracture may develop (which can present as a transverse lucency in the cortex)
Describe the term osteoarthrosis.
Some specialists want to move away from the term osteoarthritis because that disorder is not an inflammatory disorder (like rheumatoid arthritis). As such, osteoarthrosis is their preferred term.
Psoriatic arthritis commonly affects which joint in the hand?
DIPs (like OA)
Osteophytes that connect two bones are called ____________.
syndesmophytes
