Today, the ultrasound (US) represents an essential tool in the orthopaedical, rheumatological and rehabilitative setting to address the musculoskeletal causes of pain. Amongst the commonest causes of shoulder complains lay the frequent subacromial chronic bursitis (SACB). In this condition, the thickening of the bursal walls and subsequent fusion of the two synovial sheets leads to the reciprocal loss of bursal walls gliding under the subacromial space and consequently pain. This condition represents a common cause of shoulder pain and may be easily addressed by musculoskeletal sonographers.
