Shoulder Dx/Tx

Question 1

3 bones of shoulder joint

Answer 1

clavicle, humerus, scapula (coracoid, acromion)

Question 2

3 true synovial joints of the shoulder

Answer 2

GH, SC, AC

Question 3

2 functional joints of the shoulder

Answer 3

Suprahumeral

Scapulothoracic

Question 4

2 Accessory joints of the shoulder

Answer 4

Costosternal

Costovertebral

Question 5

Early shoulder aBduction

Answer 5

GH (true) + Suprahumeral (functional

Question 6

Mid-Late shoulder aBduction

Answer 6

scuplothoracic (functional) + SC (true) + AC (true)

Question 7

Humerus motion

Answer 7

F, E, 
aBd, aDd
Horiz aBd/aDd
IR, ER - 90
Circumduction

Question 8

AC evaluation

Answer 8

TART

• GH to 60 degrees horiz aBd and 60 degrees coronal aBd to max AC motion.
• GH joint into IR (=AC joint IR&raquo_space; vice versa for ER)

Question 9

Scapular Motion

Answer 9

• Elevation (up/parallel to spine)
• Depression (return from elevation)
• aBduction (protraction) - away from spine with lateral tilt around thorax
• aDd (retraction) - moving closer to spine
• Upward (forward tilt) - turning on horizontal axis so taht posterior surface faces upward and inferior angle protudes. Accompanied y longitudinal axis rotation of clavicle.
• Up/down rotation - frontal plane rotation in relation to glenoid fossa’s elevation or depression.

Question 10

SC Motion

Answer 10

Pt supine:
aBd = pt SHRUGS - should feel clavicular head/sternum = INFERIOR mvmt
aDd = flex shoulder to 90 and forcefully reach to ceiling - should feel POSTERIOR mvmt
