impingement syndrome Flashcards
What is impingement syndrome?
Impingement syndrome is one of the most common injuries of the shoulder.
What often causes impingement syndrome?
It is often caused by repetitive microtrauma from upper extremity activity performed above the horizontal plane.
Who is particularly susceptible to impingement syndrome?
Individuals participating in throwing activities, swimming, and racquet sports are particularly susceptible.
What causes impingement syndrome at a physiological level?
It is caused by the humeral head and the associated rotator cuff attachments migrating proximally and becoming impinged on the undersurface of the acromion and the coracoacromial ligament.
What are the signs and symptoms of impingement syndrome?
Signs and symptoms include discomfort or mild pain deep within the shoulder, pain with overhead activities, a painful arc of motion (70-120 degrees abduction), positive impingement sign, and tenderness over the greater tuberosity and the bicipital groove.
What is the initial treatment for impingement syndrome?
Initially, treatment includes RICE, NSAIDs, and activity modification.
What does treatment include once impingement syndrome is tolerated?
Once tolerated, treatment includes rotator cuff strengthening and scapular stability exercises.
What is included in long-term prevention of impingement syndrome?
Long-term prevention includes continued strengthening of the rotator cuff and scapula stabilizers, along with improved biomechanics related to sport-specific or relevant work activities.
