Test 4

Question 1

What is the term given to the proximal end of the clavicle?

Answer 1

Sternal extremity

Question 2

Which of the following structures is considered most posterior?

Coracoid process

Glenoid process

Scapular spine

AC joint

Answer 2

Scapular spine

Question 3

Which of the following structures is considered to be most inferior?

Deltoid tuberosity

Lesser tubercle

Acromion

Surgical neck

Answer 3

Deltoid tuberosity

Question 4

What structure is located on the lateral aspect of the scapular spine?

Answer 4

Acromion

Question 5

List the three borders of the scapula?

Answer 5

Medial, lateral and superior

Question 6

Which scapular border would you find the scapular notch?

Answer 6

Superior border

Question 7

What is the joint classification and type of movement of the SC joint?

Answer 7

Diarthrodial; plane

Question 8

What is the joint classification and type of movement of the AC joint?

Answer 8

Diarthrodial; plane

Question 9

Where is the CR centered for a AP projection, external rotation of the shoulder?

Answer 9

1” inferior to coracoid process

Question 10

How much CR angle is required for the AP oblique-Grashey method?

Answer 10

None. Perpendicular to IR

Question 11

Which of the following positions provides an inferosuperior axial projection of the glenohumeral joint?

Answer 11

Clements modification

Question 12

What are the primary technical differences between a Scapular Y projection and Tangential-Neer method?

Answer 12

Neer method required a 10-15 degree caudad angle. No CR angle with Scapular Y projection utilizes a perpendicular CR . The Scapular Y is performed for dislocation and proximal humeral fractures. The Neer method demonstrates the supraspinatus outlet.

Question 13

List three lateral projections can be performed safely for a possible proximal humeral fracture fracture?

Answer 13

Scapular Y , Transthoracic lateral projections and Garth Method

Question 14

Situation: A patient comes to radiology with a history of chronic shoulder dislocation. The orthopedist suspects a Hill-Sachs defect created by the frequent dislocations. Part one: Define a Hill-Sachs defect Part 2: Which specific position will best demonstrate it? Be specific. Part three: Describe briefly how the position/projection is performed

Answer 14

Part one: A defect (fracture) of the posterolateral aspect of the humeral head due to dislocation. Part two: The inferosuperior axial projection with exaggerated external rotation of 45 degrees. Part three: Patient is supine. The affected arm is abducted 90 degrees with the palm facing upward. Rotated the affect arm 45 degree externally to profile a possible Hill-Sachs defect. The CR is angled 25 - 30 degrees lateromedial from a horizontal alignment and enters the axilla.

Question 15

Which of the following CR angulations is recommended for an asthenic patient for the AP axial of the clavicle projection?

Answer 15

30 degrees cephalad

Question 16

Situation: A patient comes in with a possible shoulder separation. Part one: Which projections or method would you perform to determine shoulder separation? Part two: What must you rule-out first prior to performing any special projections?

Answer 16

Part one: Pearson method with non-weight and weight-bearing projections. Part two: You must rule-out clavicle fracture first before attempting a weight-bearing study.

Question 17

Situation: A patient comes to radiology with a possible impingement of the shoulder girdle. List two projections that would best demonstrate a possible impingement within the supraspinatus fossa

Answer 17

Tangential projection-Neer method, Apical Axial AP projection

Question 18

Defect or fracture of posterolateral aspect of humeral head

Answer 18

hill-sachs defect

Question 19

Caused by chronic anterior dislocation of humeral head

Answer 19

hill-sachs defect

Question 20

Fracture of anteroinferior rim of glenoid labrum

Answer 20

Bankart lesion

Question 21

Chronic anterior dislocation of humeral head

Answer 21

Bankart lesion

Question 22

Small avulsions of glenoid fossa can result

Answer 22

Bankart lesion

Question 23

what major muscle is most commonly involved with rotator issues

Answer 23

supraspinatus

Question 24

where is the supraspinatus muscle located

Answer 24

on the posterior side of the scapula

Question 25

Which is the most inferior muscle of the 4 major muscle of the rotator cuff

Answer 25

infrspinatus

Question 26

about 65% of shoulder dislocation are _____ dislocations

Answer 26

anterior

Question 27

what are the 4 major rotator cuff muscles

Answer 27

suprspinatus, infraspinatus, subcpaularus, teres minor

Question 28

what position compliments the neer method

Answer 28

apical ap axial
