This is the recurrence rate of shoulder dislocations (10% range).
What is 80-90%?
This rotator cuff muscle is the most commonly injured.
What is the Supraspinatus?

What is the Scapulothoracic Joint?
This is the name of the deformity that you will observe after a biceps rupture.
What is a Popeye Deformity?

What is the Glenohumeral Joint?

What is the mid section of the clavicle?
Which direction of an SC joint dislocation is considered a medical emergency?
What is a posterior dislocation?
A patient with a rotator cuff tear will complain of this symptom, especially when trying to perform overhead activities.
What is shoulder instability/feeling like the shoulder will pop out of place?
These 4 muscles make up the rotator cuff.
What is the supraspinatus, infraspinatus, teres minor, and subscapularis?

What is the Glenoid?
The MOI for a biceps rupture.
What is a powerful ECCENTRIC contraction?
These two shoulder actions, when forced or occur at a high velocity, are responsible for causing dislocations of the shoulder joint.
What is abduction and external rotation?
The MOI for a biceps tendon rupture.
What is a powerful eccentric contraction?
This muscle is responsible for holding your scapula to your thoracic spine. If not function properly, it can lead to scapular winging.
What is the Serratus Anterior?
This scapular landmark is inferior to the acromion and clavicle.
What is the coracoid process?
These 3 structures are the common cause of shoulder impingement.
What is the supraspinatus tendon, biceps tendon, and bursa?
A patient with a clavicle fx will most likely be doing these 2 things in an attempt to decrease their pain.
What is supporting their arm and tilting their head to the injured side?
