ALREADY GRADED A+. LATEST 2024
1. The shoulder girdle is comprised of which four joints?: Sternoclavicular (S/C)
Acromioclavicular (A/C)
Glenohumeral (G/H)
Scapulothoracic Articulation (S/T)
2. Sternoclavicular joint is what kind of joint: Complex saddle joint
3. Increases the congruity of the highly irregular joint surfaces: Sternoclavicular joint
articular disc
4. Ligaments of the sternoclavicular joint: SC ligament, interclavicular, Costoclavicular
5. Achieved by placing the arm down at the side of the body: Loose packed position of the
SC joint
6. Achieved through maximum shoulder elevation, when the GH joint exceeds greater
than 110° of flexion or abduction. The clavicle must upwardly rotate to achieve this.:
Closed packed position of the SC joint
7. Conditions of the SC joint: Osteoarthritis, sprain, dislocation, all are not that common,
clavicular fracture is most likely
8. With ankylosis of a SC joint shoulder elevation is severely limited to approximately 19°:
Osteoarthritis
9. Can be very serious injury may require open reduction surgery: Posterior dislocation of
SC joint
10. Most common dislocation, usually occurs due to direct trauma to the side of the
shoulder, such as an impact or a fall, typically benign: Anterior dislocation with superior
medial displacement of SC joint
11. Acromioclavicular joint is what kind of joint?: Planer joint with incongruent surfaces
12. High degree of variability between individuals and within individuals: Articular disc of
the AC joint
13. Ligaments of the AC joint: Coracoclavicular ligament comprised of coronoid and trapezoid
ligaments, and AC ligament
14. Achieved by bringing the GH joint into 90° of abduction: AC joint closed packed position
15. This position is debatable: Loose packed position of the AC joint
16. Conditions of the AC joint: Osteoarthritis, osteolysis, AC joint dislocation or shoulder
separation
17. Resorption of the subchondral bone of the distal clavicle, can be due to trauma or
repetitive stress: Osteolysis
18. Common mechanism of injury is direct impact to the lateral aspect of shoulder or a fall
on outstretched hand, graded on damage to ligaments and displacement of clavicle, six
1/8
, types of grades of separation, grades 4 to 6 are variations of grade 3: AC joint dislocation
or shoulder separation
19. One of the most mobile joints: Glenohumeral
20. The glenohumeral joint is what type of joint: Ball and socket joint
21. The head of the humerus articulates with what. To form the GH joint: Glenoid fossa
22. The GH joint at the glenoid fossa is supported by what: Glenoid labum, ligaments, joint
capsule, rotator cuff
23. What ligaments are in the GH joint?: The superior, middle, inferior, and posterior GH
ligaments
24. What are the rotator cuff muscles? (SITS): Supraspinatus, infraspinatus, teres minor,
subscapularis muscles
25. In the coronal plane line of the scapula with approximately 38-40° of abduction: Loose
packed position of the GH joint
26. Full abduction and full external rotation: Closed packed position of the GH joint
27. Prevents inferior displacement of the humerus along with the supraspinatus, taught
with adduction and inferior and posterior translation: Superior ligament at the GH joint
28. Prevents anterior translation of the head of the humerus and external rotation,
becomes taught at 90° abduction and stabilizes internal rotation, acts as a sling for the
humeral head: Inferior ligament at the GH joint
29. Prevents posterior translation of humeral head, important, in posterior capsule
tightness: Posterior ligament at the GH joint
30. Conditions of the GH joint: Sprain/strain, impingement syndrome, bursitis, rotator cuff
tear, SLAP tear, adhesive capsulitis, dislocation, fracture
31. Resists anterior translation, an external rotation of the GH joint, continuous with the
subscapularis tendon: Middle ligament at the GH joint
32. Creates functional joint articulation and closed kinematic chain between the shoulder
complex and the thorax: Scapulothoracic articulation
33. Motions of the ST articulation: Upward and downward rotation, elevation of depression,
protraction and retraction, internal and external rotation, anterior and posterior tipping
34. Conditions involving the ST articulation: SICK scapula, GIRD/glenohumeral internal
rotation deficiency, upper crossed syndrome, impingement syndrome
35. Scapular malposition, inferior medial border winging, coracoid tenderness, dyskinesis:
SICK scapula
36. Loss of internal rotation tested at the 90/90, posterior capsule tightness, common in
overhead athletes, especially throwers: GIRD
37 SICK, GIRD, and upper crossed can narrow the S/S: Impingement syndrome 38. Designed
to assess the firing pattern of muscles during a particular motion, and the quality of their
performance, involve a series of muscles acting as Agonists, synergists, and stabilizers that
combine to produce the movement: Movement patterns
39. In movement patterns what phase is more important to chiropractors: Early phases of
movement
