MSK Flashcards
A Baker’s cyst is an example of:
communicating bursa
Which imaging artifacts bends the sound beam to an oblique path?
Refractile shadowing
(Refractile shadowing occurs when the sound beam bends as it passes through different tissues with varying acoustic impedances, causing the beam to follow an oblique path. This results in shadowing artifacts and can lead to misinterpretation of the image.)
What connects bone to bone?
Ligaments connect bone to bone.
Acute rotator cuff tear may be caused by
falls
shoulder dislocation
years of playing sports (eg, tennis)
Tendinitis is seen more often in the shoulder, wrist, and _____________.
Elbow
Where is the Achilles tendon located?
the back of your ankle
What kind of muscle patter are your deltoids?
Pennate muscle
What type of muscle are your biceps?
Fusiform muscle
Clinical findings of tendonitis include:
-Pain
-Edema
-The area is warm to touch
___________ test can be performed to determine a torn Achilles tendon?
Thompson
A cystic mass located within the popliteal fossa is most likely a:
Baker cyst
The Achilles tendon connects the:
Heel to the calf muscle
In what position should the patient placed to better evaluate the Achilles tendon?
Prone
How do you perform the Thompson test?
The patient lies prone while the symptomatic calf is squeezed.
What are the keys to identifying foreign bodies with sonography?
- Use a linear array transducer
- Most foreign bodies are better visualized using a standoff pad
- Comet-tail artifact may be see posterior to metallic objects
_________ would be best described as a benign tumor comprised of fat?
Lipoma
The accumulation of synovial fluid from a weakening in the joint capsule of the knee, as seen in conditions like rheumatoid arthritis can result in a
Baker cyst
A complicated Baker cyst may contain a thin flap of tissue referred to as
Pannus
Inflammation of the tendon and synovial tendon sheath is referred to as
Tendosynovitis
Acoustic shadowing caused by bending of a sound beam at the edge of a curved reflector is referred to as
Refractive
Fluid within the synovial sheath is indicative of
Tendosynovitis
A partial tear of a tendon typically appears as
Focal hypoechoic areas within the tendon
Tendons sonographically appear as
Fibrous structures connecting muscles to bone show echogenic
When do we use standoff pad during scanning?
When we scan the superficial strucutres
Bullets, shrapnel, and other metallic objects may cause
Comet-tail artifact
