Shoulder Girdle

Question 1

Where does the greater tubercle lie on the humerus

Answer 1

Superior aspect

Question 2

IF the arm is internally rotated, where is the lesser tubercle moved?

Answer 2

Laterally to the proximal border

Question 3

Amount of patient rotation for a Grashey view

Answer 3

35 degree

Answer 4

60 degree,

Question 5

Collimation for AP shoulder: internal, neutral and external

Answer 5

collimate to 24x30 IR.

Question 6

Which shoulder rotation projections the lesser tubercle in profile and which doesnt project either tubercle in profile

Answer 6

Internal = lesser

Neutral = neither.

Question 7

Answer 7

Ribs SI.

Image used when patient cant move at all?

Answer 8

Transthoracic Humerus.

Question 9

Angulation for AP axial clavicle

Answer 9

15 cephalad. (ensure to mark the image as angulated)

Question 10

What breathing should be used on a AP of AC joint?

Answer 10

Expiration

Question 11

Arm postiong for lateral humerus

Answer 11

INTERNAL rotation. need to SI condyles.

Question 12

Why may a lateral humerus need 2 projections?

Answer 12

Prox and Distal humerus can have a differnt window width.

Question 13

Which type of AC joint dislocation isnt radiographically present?

Answer 13

Type 1

Question 14

What is anotehr name for the scapula outlet projection?

Answer 14

Neers

Question 15

Angulation for Neers

Answer 15

LAteral scapula with 15 caudad angulation

Question 16

Why is more angulation less preferable for a lawerence projection?

Answer 16

Means the IR has to be pushed further into patients neck

Answer 17

Lawerence

Answer 20

Anteriorly

Question 21

THe two types of consent

Answer 21

explicit and implied

Question 22

WHy does FFD have to be increased for projections for patients with broader shoulders?

to decrease magnification

Question 23

Best projection to visualise the greater tubercle?

Answer 23

Grache.

Question 24

Common sites for insufficency and pathological #

Answer 24

Inter trochanter of femur
Humeral head
VErtebral body

Question 25

Hill-Sachs defect

Answer 25

Greater tubercle (posterolateral aspect of humerus) collides with anterior glenoid cavity causing a decompression

Question 26

Bankart lesion

Answer 26

Avulsion # to anteroiferior glenoid rim.

Labrum tears, Perthes lesion of labrum.

Predisposes to further dislocations

frozen shoulder

Ultra sound or MRI.
