Posterosuperior impingement (PSI) is an underdiagnosed cause of posterior
shoulder pain and should be differentiated from classic and external impingement.
PSI involves the internal impingement of soft tissues, including the undersurface
of the rotator cuff against the posterosuperior labrum when the arm is brought
into abduction and external rotation (ABER). Ultrasonography (US) can be useful
in the assessment of PSI because of its high resolution and ability to perform
during dynamic maneuvers in ABER. This series of 3 cases illustrates the
feasibility of US in the evaluation of PSI when the history and physical
examination implicate this condition.
