Flashcards in Lecture 3.3 Deck (22):
1

there are three synovial joints of the shoulder

two physiological joints

(no ligaments, capsules etc...)

  • steroclavicular
  • acronioclavicular
  • glenohumeral

 

Physiological:

  • Sub deltoid
  • scapulothoracic

2

The sternoclavicular joint connects the _____ limb with ______

it is a _____ joint

There are _ ligaments

The sternoclavicular joint connects the upper limg ith thorax

it is a saddle joint

There are 3 ligaments

3

What is protraction/retraction?

4

Intrinsic ligaments - connect the two bones that make up the joint

An example of an extrinisic ligament in the Sc joint is the ____________ _________

Costoclavicular ligament

 

stops the upward projection of the clavicle

5

What suppies blood to the SC joint?

Internal thoracic and suprascapula artery

 

 

6

true or False

 

The subclavious nerve supplied inneravation to the SC joint

 

true

7

An impact to the front if the body can lead to

 

sternoclavicular sublaxation

8

True or False

In the AC joint, the coronoid ligament lies more vertically than the Trapezoid ligament

 

true

9

The trapezoid ligament stops ____ , _________and __________of the clavicle

The trapezoid ligament stops rotation, protraction and retraction of the clavicle

10

The glenohumeral joint is a ______ ball and socket articulation between the head of the humerus and the ______ cavity of the scapula

The glenohumeral joint is a synovial ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula

11

The fibrocartiagenous ring surround the GH joint?

Glenoid Labrum

 

extra stability, deepens socket

12

true or false

 

The tendon of the long head of the bicrps starts within the GH capsule?

 

true

13

what are the main sources of blood supply for the GH joint?

Circumflex humeral arteries

14

What is the nerve suply for GH joint?

suprascaupula, axillary and lateral pectoral

15

The intrinsic ligaments of the GH joint are

Caracoumeral

glenohumeral (superior, middle, inferior)

16

What is the definition of maximal stability of a joint?

The point where the articular sufaces make the most contact

17

terres major acts in _______ of shoulder

extension

18

The subarcomial bursae...

minimises friction

19

The glenohumeral rhythm is ..

Scapula and humerus 1:2 ratio as you abduct

20

Typically rotator cuff muscle injuries are universal - they effect each other

Which tendon can be inpinged to due lack of blood supply, and being deep in the coraco-acromial arch?

supraspinatus

21

Dislocation of the GH joint is mostly commonly...

anterior/inferior
