Muscloskeletal Radiology Slides Flashcards
Side (sagittal) + Frontal (coronal) view of:
Normal Right Shoulder
& Rotator cuff
Sagittal + Coronal (front) view of:
Right shoulder with rotator cuff tear
(in supraspinatus tendon)
- white area above humeral head = fluid resulting from rotator cuff tear*
- black structure next to humeral head (@2 o’clock) = retracted end of torn supraspinatus tendon*
What is injured in this MRI?
SLAP tear: Superior Labrum Anterior & Posterior
- Labrum: a ring of fibrocartilage (fibrous cartilage) around the edge of the articular (joint) surface of a bone
What type of tumor is this?
What is the defining feature?
osteosarcoma of proximal humerous
feature: :moth-eaten” edges
What type of dislocation is shown?
Is this common?
anterior dislocation
of humerous (resides in front of glenoid)
- common
What type of dislocation is shown?
Is this common?
Posterior dislocation, humerus
(head resides behind glenoid fossa)
- rare
What injury is shown?
humeral fracture
(neck of humerous)
What type of fracture is this?
What nerve could be damaged?
Midshaft humeral fracture
- radial nerve
What type of fracture is this?
What 2 types of this fracture can occur?
distal humeral fracture (condylar)
- can be supracondylar or condylar
What type of elbow dislocation is this?
What are all the possible types?
posterior elbow dislocation
- posterior
- anterior
- lateral
- medial
- divergent
What is this injury know as?
What does it consist of?
Terrible Triad
- elbow dislocation
- radial head fracture
- coronoid fracture
What 2 types of MRI imaging are seen here?
left: T1
right: T2
What type of fracture is this?
metaphyseal fracture
(does NOT effect growth plate)
What type of fracture is this?
Torus or “buckle” fracture
- topmost layer of bone on one side of the bone is compressed, causing the other side to bend away from the growth plate
What type of fracture is this?
Greenstick
- one bone fractures causing the other to bend
This type of fracture is common in the arms of children:
(fracture in ulna; radius is dislocated)
Monteggia fracture
This type of fracture is common in the arms of children:
(fracture in radius; ulna is dislocated)
Galeazzi fracture
This fracture occurs across or at the growth plate:
Salter fractures or Physeal fracture
In these 2 wrist fractures the wrist bone slides over or under the ulna + radius. Identify the fractures in the top and bottom images.
top: Colles (wrist = over)
bottom: Smith (wrist = under)
Name this fracture fo the 5th metacarpal bone:
Boxer Fracture
This fracture causes Pain in the snuffbox:
Scaphoid fracture
This is a stable type of pelvis fracture:
acetablar fracture
This is a penis…I mean..uh.. unstable type of pelvic fracture:
Open book
What is wrong in this image?
Posterior hip dislocation
MRI: Throcanteric Bursitis
Avascular Necrosis
Congenital hip dislocation
Developmental Hip Dysplasia (DDH)
CT image of a sarcoma originating from the muscles of the inner thigh
What are the red arrows indicating?
Exostosis
(formation of new bone on top of existing bone)
What does this ultrasound show?
Deep Vein Thrombosis
of the common femoral vein
Where is this anyerism located?
popliteal artery
(in lower limb)
•Risk of complications:
–Thrombosis ===high
–Emboli ===high
–Rupture===low
