Term: A mechanical impingement of the subacromial structure, esp. the rotator cuff tendons, beneath the atnerior-inferior poriotn of the acromion

Impingement syndrome

27

Defn: Shoulder impingement syndrome

Term: A mechanical impingement of the subacromial structure, esp. the rotator cuff tendons, beneath the atnerior-inferior portion of the acromion

28

Q: What are the symptoms of shoulder impingement syndrome? (2)

1. Pain in the anterosuperior part of the shoulder

2. weakness and stiffness

29

Q: What is outlet impingement syndrome?

Occurs when the coracoarcomial arch encroaches on the supraspinatus outlet

30

Q: What is non-outlet impingement syndrome?

Occurs secondary to thickening or hypertrophy of the bursa or the rotator cuff tendons
