What is the Scapulothoracic interface?

Answer 3

the contiguous relationship of the anterior scapular surface with the ribs of the thorax.

very little

Question 8

Answer 8

thin and loose

Question 9

What does the shoulder capsule look like in anatomical position? Elevated?

Answer 9

-capsule is taut superiorly, hangs in a fold inferiorly; -as arm is elevated the situation is reversed

Question 12

Answer 12

Question 13

1. What is the purpose of the coracoclavicular ligament?
2. Which ligament makes it up?

Answer 13

1. Maintain the relationship between clavicle and scapula
2. Trapezoid ligament and conoid ligament

Question 14

What are the 3 glenohumeral ligaments and what do they do?

Answer 14

superior, middle and inferior

strengthen the capsule, attach to the labrum

Question 15

_________ joint motion is coupled with sternoclavicular joint movement.

Answer 15

Acromioclavicular (AC) joint

Question 16

Describe the 3 classifications of AC joint seperation.

Answer 16

• Type 1 (ligament stretch)
• Type 2 (Partial rupture AC ligaments)
• Type 3 (Complete rupture of AC and CC ligaments)

Question 17

The Scapulohumeral Rhythm

1. Which 2 joints?
2. What is the 180 degree ratio?

Answer 17

1. Shoulder joint and shoulder girdle
2. 120 degrees shoulder abduction/60 degrees shoulder girdle. 2-1 ratio.

Question 18

The Scapulohumeral Rhythm

What is the “setting phase”?

Answer 18

Essentially the first 70 degrees of movement take place at the shoulder. The first 30 degrees of abduction is termed the “setting phase”

Question 19

Purpose of scapulohumeral rhythm.

Answer 19

• less compromise of stability
• Maintaining the glenoid fossa in an optimal position
• maintain a good length-tension relationship

Question 20

Relationship between
Stability and Mobility

Answer 20

• Generally there is an inverse relationship between stability and mobility.

Question 21

Because of the extreme degree of movement available at the shoulder and the relatively poor bony articulation (the glenoid accepts only a little more than ___ of the humeral head) the shoulder relies on the ____ muscles, the ____, and the ____ to help maintain the stability of the joint.

Answer 21

• 1/3
• rotator cuff
• glenoid labrum
• deltoid

Question 22

The Elbow Joint

Answer 22

• The elbow (humeroulnar) joint is a hinge joint.
• The movements possible are flexion and extension

Question 23

Medial Ligaments of the Elbow Joint

Answer 23

Ulnar collateral: 3 bands

1. anterior from medial epicondyle to coronoid process
2. posterior from medial epicondyle to olecranon process
3. oblique: coronoid process to olecranon

Question 24

Identify the ulnar collateral ligaments

Answer 24

Question 25

Lateral Ligaments of the Elbow Joint

Answer 25

1. Radial collateral (complex): can consist of just one collateral ligament from the lateral epicondyle to the annular ligament deep into the common extensor tendon 2. or it can have several slips (including to the ulna)

The oblique cord (oblique ligament) 1. Where is it located? 2. Which way do the fibers run?

Answer 30

1. extending downward and lateralward, from the lateral side of the tubercle of the ulna at the base of the coronoid process to the radius a little below the radial tuberosity 2. in the opposite direction to those of the interosseous membrane.
