Module 6 Flashcards
(23 cards)
What is a fracture of the clavicle?
Break of the clavicle bone
What is an ACJ separation?
Separation of the acromion from the clavicle
What type of shoulder dislocation is most common?
Anterior (humerus sits anterior and medial)
What is a fibrous bankart injury?
Labral detachment
What is a bony bankart injury?
Fracture of glenoid
What is a hill-Sachs injury?
Deformity of humeral head
Can you gain information about a potential RTC tear from an X ray?
Yes because there is a superior migration of humeral head due to muscle imbalance
Go back and know how to visualize all these shoulder radiographs
AP in ER and IR
AP of the ACJ
AP of the scapula
Lateral scapula
Know how to visualize all the planes of the shoulder on an MRI
Axial and coronal
Know how to visualize labral tear on a MRA
SLAP and bankart lesions
What is the differences between ultrasound and MRI for visualizing RTC tears?
MRI- well visualized for complete and partial tears
Ultrasound- less expensive and can see complete tears well (limitations in detecting partial tears)
Who is the elbow extension test used for?
Patients 14 years or older who have had an injury less than 24 hours ago
What is the elbow extension test?
Having patient fully extend and lock elbow (inability is a positive test for bone injury)
What is always the 1st test for elbow pain acute or chronic?
Radiographs
What is a nightstick fracture?
Fracture of the mid portion of ulna
What is a monteggia fracture?
Proximal ulna fracture with radial head dislocation
What is a galeazzi fracture?
Distal radius fracture with ulnar head dislocation
What is a green stick fracture?
Incomplete fracture due to flexibility of young bones (common in forearms)
What is a torus (buckle) fracture?
Fall on outstretched hand leading to distal radius irregularity
What are the standard views of the wrist?
PA (carpals and ulnar variance)
Oblique (1st and 2nd metacarpals, hamate, triquetrum, and trapezium)
Lateral (dorsal/volar displaced fragments and scapholunate angle)
What view allows us to see hook of hamate clearly?
Carpal tunnel view
What is Kienbochs disease and how is it detected on images?
Osteonecrosis of the lunate (seen on radiographs)
What are the standard views of the hand?
PA (sesamoid bones)
Oblique (phalanges and metacarpals)
Lateral (dorsal/volar displaced fragments)
