Ultrasound imaging of the shoulder joint has become an increasingly valuable diagnostic tool in evaluating shoulder joint pathology due to its accessibility, cost-effectiveness, and the ability to provide real-time, dynamic assessment. The shoulder, being a highly mobile and complex joint, is prone to a variety of musculoskeletal disorders, including rotator cuff tears, impingement syndrome, tendinopathy, bursitis, etc. which can be effectively diagnosed with ultrasound. Ultrasound offers several advantages including the ability to perform dynamic imaging, as well as the potential for guiding therapeutic interventions like injections or aspirations. This chapter elucidates the US technique for shoulder ultrasound examination and appearances of normal structures and pathological changes.
