Answer 1

Glenohumeral
Scapulothoracic
Acromioclavicular
Sternoclavicular

Question 2

Answer 2

Depression and medial rotation

Question 3

Scapulothoracic medial glide improves

Answer 3

Retraction
Depression
Medial rotation

Question 4

Scapulothoracic lateral glide improves

Answer 4

Protraction
Elevation
Lateral rotation

Question 5

Classification of the Glenohumeral joint.

Answer 5

Structural: synarthrotic
Functional: diarthrotic
Subtype: ball & socket
Axis of rotation: multiaxial

Question 6

Range of Motion for Glenohumeral joint

Answer 6

Flexion. 180
Extension. 45
Abduction. 180
Adduction. 45
Medial rotation. 70
Lateral rotation. 90
Horizontal adduction:  45
Horizontal abduction:  100

Question 7

Articular surfaces of the GH joint

Answer 7

Scapula (glenoid fossa) CONCAVE

Humerus (humeral head) CONVEX

Question 8

Glenoid labrum

Answer 8

Narrow rim of fibrocartilage that improves the fit in the GH joint.

Question 9

GH capsule

Answer 9

Strength: weak

Thin and lax, allows wide range of movement. Pleated. When should adducted the folds can adhere to one another.

Question 10

Ligaments of the GH joint

Answer 10

GH ligaments

Coracohumeral ligaments

Transverse humeral ligament

Question 11

Glenohumeral ligaments

Answer 11

Three weak bands of fibrous tissue that strengthen front of the capsule.

Superior, middle and inferior

Question 12

Coracohumeral ligament

Answer 12

Accessory ligament. Strengthens capsule above GH joint

Coracoid process –> greater tuberosity of humerus.

Question 13

Transverse humeral ligament

Answer 13

Bridges gap between two tuberosities

Question 14

Bursae of the GH joint

Answer 14

Subscapular
Subdeltoid
Subacromial
Subcoracoid

Question 15

Innervation of the GH joint

Answer 15

Suprascapular
Axillary
Lateral pectoral

Question 16

Arteries of the GH joint

Answer 16

Branches of axillary and subclavian

Question 17

What is the most common dislocation of the GH joint?

Answer 17

Anterior

Question 18

GH joint: resting position

Answer 18

55-70 degrees abduction
30 degrees horizontal adduction
Neutral rotation

Question 19

GH joint: closed pack position

Answer 19

Max abduction and external rotation

Question 20

GH joint capsular pattern of restriction

Answer 20

External rotation
  more restricted than
Abduction
  which is more restricted than
Internal rotation

Question 21

Inferior glide of the GH joint improves?

Answer 21

Abduction

Question 22

Posterior glide of the GH joint improves

Answer 22

Flexion, internal rotation, horizontal adduction

Question 23

Anterior glide of the GH joint improves

Answer 23

External rotation, extension, horizontal abduction

Question 24

GH Flexion is helped by what mobilization?

Answer 24

Before 90°: posterior glide | After 90°: inferior glide
