Transcript of Acromioclavicular Joint Sprain

Joint Sprain
(Mild to Moderate)

By: Kate Howard and Emily Perkinson
The AC Joint
Where is it/ What is the function of the AC Joint?
Found it!
Where is it formed?
Distal end of the clavicle and the acromion
Gliding joint within the shoulder
Allows the ability to raise arm above the head
Pivot point that aids the movement of the scapula to increase ROM.
Between Clavicle and the Scapula
The Rockwood Classifications
Why does this injury occur?
Direct blow to the upper area of the shoulder
Direct lateral blow to the deltoid area of the shoulder
Falling onto an arm in adduction
Likelihood of sprain is often affected by previous injury to the shoulder, genetics, and problems with rotator cuff.
Return-to-activity considerations
Lift weights at an appropriate level
Warming Up and Stretching
Being in contact sports is a risk
As a AC joint sprain is an injury resulting from a direct blow the preventions are not as effective.
Type I:

Point tenderness
No visible shift in shoulder
no tear in CC ligament
partial tear of AC ligament
Type II:
prominent swelling
noticeable shift in shoulder
partial tear of CC ligament
complete tear of AC ligament
Type III:
complete tear in AC ligament
complete tear in CC ligament
superior displacement
have patient sit down
bare shoulder for accurate data
compare the unaffected side to the affective side
look at from anterior and superior views to note any subtle displacements of the joints
palpate areas surrounding the AC joint
locate for soft tissue defects
identify and record all observations
obtain x-ray
cross arm flexion test
Type I:
sling for 7-10 days
some PT is reccomended
NSAIDs often suggested
Type II:
NSAIDs are recommended
sling is worn for 2-4weeks
PT after symptoms have subsided

Type III:
Tape the Joint
Immobilize for 6-12 weeks
Cortisone injections
TENs electrotherapy
Light PT
Do sport specific activities to test shoulder in gamelike situations
Have patient dribble, shoot, jump
Slow progression in full contact games
Strengthening exercises to strengthen and prevent (outward rotation and scapular rotation)
