Shoulder impingement is a common musculoskeletal (MSK) condition where the rotator cuff tendons or bursa become compressed as they pass through the subacromial space. This compression often occurs during arm elevation, leading to pain, weakness, and reduced range of motion. It is frequently caused by repetitive overhead activities, bony spurs, or inflammatory changes, impacting daily activities and athletic performance.
Ultrasound is a valuable diagnostic tool for shoulder impingement, allowing real-time visualization of the rotator cuff tendons for signs of tendinopathy, tears, or bursitis. It can assess the dynamic movement of structures during arm elevation, aiding in the identification of impingement. Medical professionals leverage ultrasound to guide injections and monitor treatment progress, making it essential for accurate diagnosis and effective management of shoulder pain.
