Costoclavicular ligament

A

Limits elevation

13
Q

Articular disc of sternoclavicular ligament

Divides joint cavity and increases mobility

14
Q

Stability of sternoclavicular joint

A

Very stable

Clavicle fracture more common

15
Q

Which part of clavicle elevated during fracture?

A

Medial portion because of sternocleidomastoid pulling up on it

20
Q

Glenohumeral ligaments

A

Thickenings of the joint capsule located on superior and anterior sides

21
Q

Biceps brachii tendon

A

Passes through GH joint and stabilizes

Prevents superior displacement

22
Q

Rotator cuff muscles

A

Surround the GH joint all but inferior

23
Q

Coracoacromial ligament

A

Prevents superior displacement of head of humerous

24
Q

Glenoid labrum

A

Cartilaginous ring surrounding the glenoid fossa that deepns it

25

GH dislocation

A

Normally inferior
Protruding acromion
Closed reduction and immobilization…surgery
