Imaging Diagnosis of Rotator Cuff Pathology and Impingement Syndromes

Chapter

Abstract

Rotator cuff disease is common and the diagnosis of impingement syndromes requires all available information, including history, physical examination, and imaging. A commonly used classification scheme of the various shoulder impingement syndromes is to divide them based on those where the pathogenesis resides outside the glenohumeral joint capsule (termed external impingement) and those residing inside the glenohumeral joint capsule (termed internal impingement). External impingement syndromes include subacromial impingement and subcoracoid impingement. Internal impingement syndromes include posterosuperior impingement, which belongs in the spectrum of abnormalities leading to the disabled throwing shoulder, and anterosuperior impingement. Each impingement syndrome is a distinct entity, often affecting different demographics of patients, but more than one type of impingement syndrome may be seen in an individual. This chapter (1) summarizes our current knowledge of the anatomy of the structures related to impingement, including the rotator cuff and biceps pulley; (2) reviews the multi-modality imaging manifestations of rotator cuff disease and the various impingement syndromes; and (3) reviews the expected and abnormal appearances of the rotator cuff after surgical therapy.
