Shoulder Flashcards
What are the four muscles that make up the rotator cuff? Name name anterior to posterior
Subscapularis
Supraspinatus
Infraspinatus
Teres minor
What is the largest bursa and the shoulder
Subacromial subdeltoid bursa
What do ligaments do
Connect bone to bone
How much does the glenoid cover the humerus head
25 to 30%
How much does the labrum cover over the humeral head
50%
What is the main stabilizer of the shoulder
Inferior glenohumeral ligament
What imaging the labrum how is your axial plane and coronal plane positioned
Axial is anterior to posterior
Coronal is superior to inferior
What is a good landmark position for the patient when lying on the table
Make sure the epicondyles are parallel to the table top. External rotation is best
Make sure AP elbow and thumbs up this elongate the rotator cuff muscles
If the shoulder has an impingement syndrome what tendon are we looking at
Supraspinatus tendon
T1 best demonstrates?
T2 best demonstrates?
PD best demonstrates
Bone marrow and anatomy
Pathology
Anatomy and bright fluid
If there’s a hill Sachs pathology of the shoulder what level is it at
Coracoid process
What do you use to line up an oblique sagittal and an oblique coronal
On the sagittal make sure you were line perpendicular to the glenoid
On the coronal make sure you are parallel with the scapular spine
What’s a low signal intensity on the bicipital groove
The biceps tendon
What is the best plane to view the supraspinatus tendon
Oblique Coronal
What is the best plane to view the gleno labrum
Axial
