impingement syndrome
Pronunciation: im-PINJ-ment SIN-drohm
Compression and irritation of soft tissues, commonly in the shoulder, causing pain and limited range of motion.
Full Definition
A clinical condition where soft tissues become compressed between bone surfaces during normal joint motion, most commonly affecting the shoulder joint. Shoulder impingement occurs when the rotator cuff tendons and bursa become trapped between the humeral head and acromion during arm elevation. This leads to inflammation, pain, and potentially tendon tears if left untreated. The condition can be primary (due to anatomical factors) or secondary (due to instability or muscle imbalances).
Usage
Usage note: Specify anatomical location when relevant. Distinguish from rotator cuff tears and frozen shoulder.
