rotator cuff impingement
Pronunciation: ROH-tay-tor kuf im-PINJ-ment
Compression of rotator cuff tendons against the undersurface of the acromion during shoulder elevation.
Full Definition
Rotator cuff impingement syndrome occurs when the rotator cuff tendons, particularly the supraspinatus, become compressed between the humeral head and the undersurface of the acromion during overhead arm movements. This compression can lead to inflammation, pain, and eventually tendon degeneration or tears. Primary impingement results from anatomical factors such as acromial shape or bone spurs, while secondary impingement occurs due to shoulder instability or muscle imbalances. The condition is particularly common in overhead athletes and workers who perform repetitive overhead activities.
Usage
Usage note: Distinguish between primary and secondary impingement when documenting etiology.
