flashcards 3 shoulder different csv
Long Head: biceps tendon: origin?
within the shoulder joint capsule of the glenoid labrum, and it is wrapped in a synovial sheath. Action Flex, supination
Origin of the short head of the bicep brachii
Coracoid processo f the scapula
What is the combined interface that seperates the bicep tendon and deltoid
Tendon Sheath and Deltoid fascia (pic)
External rotation will do what to the bicep tendon
medial subluxation of the tendon
What it the Popeye sign?
Rupture of the long head of the bicep, short head still intact.
What ar the 3 visual criteria for tendinosis
- Hyperechoic “inhomogenours”..not uniform..2. Thickened Neovascularity.. Blodd supply for abnormal tissue 3. Non-fibrous echotexture no uniform fibrous echotexture
If I am having probles picking up Power doppler or neovascularization or angio-fibro-blastic infiltration (new blood vessel formation within abnormal tissue, a perculating blood flow with power doppler. What can I do with Doppler frequency, 2. Sample Area and Pulse repetittion frequecy (PRF)
- Doppler Frequency: Lower frequecny more penetration Higher freq. for superficial 2. Sample Area: Make the box as small as possible and apply “steering” (trapezoidal shape of sample area) to enhance “doppler shift”, more sensitivity 3. PRF-use a low value for the highest sensitivity
High or Low color Priority for dopler guidelines
High: Color priority has to do with both the grayscale and color dopper going on at the same time. So, which one will dominate when looking at the image. May need to adjust the color prioity.
Doppler guidelines for best image of power doppler
- Turn up gain until random noise is encountered and then lower it until noise dissaperars 2. Persistence (smooth image by frame averaging), use low value
What is the doppler guideline short list?
- Freq appropriate to depth, 2. Sample area: small and steered, 3. PRF low, 4. Color priority is high, Persistence is low, 6. Patient is relaxed and 7. Proble pressue is light
Long head of bicep tendon travels under what muscule/tendon?
Pec Major, inter-tubercular attachment
What does the subscapularis tendon do?
Medially rotate and helps center the humeral head in the glenoid fossa
How do you get a subscapularis tear?
Not common: forcful hyperextension or external rotation of the abducted arm
What does the suprspinatues do? A progression
It initiates abduction and becomes secondary to deltoid action
What are the three types of supraspinatues tendon tears
Type I-cuff degeneration/tendinosis without visible tears on bursal or articular surface. Type II-Cuff degnereration/tendinosis with partial tears on bursal or articular surfaces Type III-complete thickness rotator cuff tears of varying size, complexity and functional comprimise
What is a Rim Rent tear?
an edge/border opening caused by ripping of SS
What is the most common partial tear of the supraspinatues?
PASTA tear: partial articular supraspinatus tendon avulsion-a partial thickness articular surface tear at the insertion of the SS
What is a articular surface tear?
- not over full thickness of the tendon 2. has a connection/commnuication with the articular cartilage 3. Has no connection with the bursa 4. Can have a connection with the greater tuberosity (LAX, recall normal enthesis), 5. Usually no or little volume loss
What is a intra-substance/intra-tendinous tear?
- Not over the full thickness of the tendon 2. no connection/communication with the articular cartilege 3. No connection with the bursa 4. can have a connection with the greater tuberositiy 4. usually no volume loss
What is a complex tear?
Intra-tendinous tear that may communicate with articular or bursal surfaces
Do tears display a doppler signal?
No; but tendinosis does/abnormal tissue
