Q

Why is there a need to perform surgery immediately in a pt with a complete clavicular fx

A

in order to prevent the jeopardizing the post structures seen in the clavicle (costoclavicular space: brachial plexus and subclavian artery)

16
Q

This is the joint seen in the sternum and medial end of the clavicle

A

SC joint

17
Q

What is the type of joints of the SC joint

A

saddle/sellar

18
Q

What is the functional classification of sternoclavicular joint

A

diarthrodial (ball and socket)

19
Q

If the clavicle depresses, what is the arthrokinematics happening in the sternoclavicular joint

concave moving

A

Roll: inferiorly
Glide: superiorly

19
Q

If the clavicle elevates, what is the arthrokinematics happening in the sternoclavicular joint

concave moving

A

Roll: superiorly
Glide: inferiorly

20
Q

If the clavicle protracts, what is the arthrokinematics happening in the sternoclavicular joint

convex moving

A

Roll: anteriorly
Glide: anteriorly

21

If the clavicle retract, what is the arthrokinematics happening in the sternoclavicular joint

A

Roll: posteriorly
Glide: posteriorly

22
Q

The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH ABD is done?

A

Clavicular ELEVATION = sc disc @ STERNUM

23
Q

The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH extension is done?

A

Clavicular RETRACTION = sc disc @ CLAVICLE

24
Q

The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH horizontal ADD is done?

A

Clavicular PROTRACTION = SC DISC @ CLAVICLE

25
Q

The SC disc acts as a hinge or pivot during arm motion. What happens to the disc whenever the clavicular DEPRESSION is done

A

sc disc @ STERNUM

26
Q

When the clavicle depresses, what ligament LIMITS too much DEPRESSION?

A

interclavicular lig

27
Q

What ligament limits clavicular retraction?

A

sternoclavicular lig

28
Q

What ligament limits clavicular elevation?

A

costoclavicular lig

29
Q

When the clavicle protracts, what ligament limits too much protraction?

A

sternoclavicular lig

30
Q

What ligament if weakened or lax, may result to compression of costoclavicular space?

A

interclavicular lig.

31
Q

During circling motions of the arm and UE motions, what joint acts a hinge or pivot?

A

SC joint and SC disc

32
Q

What happens to the clavicle when SH is elevated >90

A

clavicle rotates posteriorly

33
Q

What happens to the clavicle when SH is elevated >110 deg

A

post rotation and elevation of the clavicle stops

34
Q
