CLAVICLE Flashcards
Anatomical description of clavicle
-long slender S shape bone the lies of the rooT of the neck
Anterior orientation of clavicle
Middle 2/3: convex
Middle 1/3: concave
Posterior orientation of clavicle
Middle 2/3: concave
Middle 1/3: convex
This is the most commonly fractured bone in the human body?
Clavicle
MOI for clavicular fx
FOOSH
FOS
This mm pulls the medial fragment of the clavicle superiorly if fx occurs
SCM
This mm pulls the lateral fragment of the clavicle medially if fx occurs
Pecs major
This pulls the lateral fragment of the clavicle inferiorly if fx occurs
gravity
What are the structures that passes through the costoclavicular space?
Subclavian artery
Brachial plexus
Seen in between clavicle and first rib
Costoclavicular space
What portion of the brachial plexus passes posteriorly through the costoclavicular space forward and downward
Inferior portion of the brachial plexus
What are the structures that may be affected in which may result with the complication of a clavicular fx
Subclavian artery
Brachial plexus
This is the immediate management done for complete clavicular fx
surgery
Why is there a need to perform surgery immediately in a pt with a complete clavicular fx
in order to prevent the jeopardizing the post structures seen in the clavicle (costoclavicular space: brachial plexus and subclavian artery)
This is the immediate management done for INcomplete clavicular fx
Bandaging technique
What bandaging technique is used in an incomplete clavicular fx?
FO8 to retract SH
This is the joint seen in the sternum and medial end of the clavicle
SC joint
What is the type of joints of the SC joint
saddle/sellar
What is the functional classification of sternoclavicular joint
diarthrodial (ball and socket)
If the clavicle depresses, what is the arthrokinematics happening in the sternoclavicular joint
concave moving
Roll: inferiorly
Glide: superiorly
If the clavicle elevates, what is the arthrokinematics happening in the sternoclavicular joint
concave moving
Roll: superiorly
Glide: inferiorly
If the clavicle protracts, what is the arthrokinematics happening in the sternoclavicular joint
convex moving
Roll: anteriorly
Glide: anteriorly
If the clavicle retract, what is the arthrokinematics happening in the sternoclavicular joint
Roll: posteriorly
Glide: posteriorly
The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH ABD is done?
Clavicular ELEVATION = sc disc @ STERNUM
The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH extension is done?
Clavicular RETRACTION = sc disc @ CLAVICLE
The SC DISC acts as a hinge or pivot during arm motion. What happens to the disc whenever the SH horizontal ADD is done?
Clavicular PROTRACTION = SC DISC @ CLAVICLE
The SC disc acts as a hinge or pivot during arm motion. What happens to the disc whenever the clavicular DEPRESSION is done
sc disc @ STERNUM
When the clavicle depresses, what ligament LIMITS too much DEPRESSION?
interclavicular lig
What ligament limits clavicular retraction?
sternoclavicular lig
What ligament limits clavicular elevation?
costoclavicular lig
When the clavicle protracts, what ligament limits too much protraction?
sternoclavicular lig
What ligament if weakened or lax, may result to compression of costoclavicular space?
interclavicular lig.
During circling motions of the arm and UE motions, what joint acts a hinge or pivot?
SC joint and SC disc
What happens to the clavicle when SH is elevated >90
clavicle rotates posteriorly
What happens to the clavicle when SH is elevated >110 deg
post rotation and elevation of the clavicle stops
Elevation of the clavicle happens @ what range of SH elevation
1-110 deg of SH elevation
