“…In addition, although US is not primarily used in the setting of trauma, it is more sensitive than radiography for the identification of grade I AC joint injuries, which appear as softtissue swelling and capsular distension on US images. The US findings of more severe traumatic AC joint injuries are similar to the radiographic findings (Fig 9) (27,29,30).…”

“…On US images, only the superficial aspect of the joint is seen well, and it has an overlying hypoechoic joint capsule flanked by the hyperechoic bone acoustic landmarks of the distal clavicle and acromion. The fibrocartilaginous disk may be seen as a thin linear hyperechoic structure in the center of the joint (27).…”

1Shoulder pain is one of the most common musculoskeletal conditions encountered in primary care and specialty orthopedic clinic settings. Although magnetic resonance (MR) imaging is typically the modality of choice for evaluating the soft-tissue structures of the shoulder, ultrasonography (US) is becoming an important complementary imaging tool in the evaluation of superficial softtissue structures such as the rotator cuff, subacromial-subdeltoid bursa, and biceps tendon. The advantages of US driving its recent increased use include low cost, accessibility, and capability for realtime high-resolution imaging that enables dynamic assessment and needle guidance. As more radiologists are considering incorporating shoulder US into their practices, the development of a standardized approach to performing shoulder US should be a priority to facilitate the delivery of high-quality patient care. Familiarity with and comfort in performing a standardized shoulder US examination, as well as knowledge of the types of anomalies that can be evaluated well with US, will enhance the expertise of those working in musculoskeletal radiology practices and add value in the form of increased patient and health care provider satisfaction. This review describes the utility and benefits of shoulder US as a tool that complements MR imaging in the assessment of shoulder pain. A standardized approach to the shoulder US examination is also described, with a review of the basic technique of this examination, normal anatomy of the shoulder, common indications for shoulder US, and characteristic US findings of common shoulder diseases-with select MR imaging and arthroscopic correlation. Abbreviations: AC = acromioclavicular, IST = infraspinatus tendon, LHBT = long head of the biceps tendon, RC = rotator cuff, SASD = subacromial-subdeltoid, SST = supraspinatus tendon, SubST = subscapularis tendon

“…In the clinical setting, ultrasound examination has been widely used for patients with shoulder symptoms because of a number of advantages, including easy accessibility to both the symptomatic and asymptomatic sides, low cost and patient comfort [5,8]. The present study suggests that a superior capsular bulging is one of the specific findings for painful AC joints in adolescent baseball players, which could also be a helpful diagnostic tool for this condition.…”

“…It is also more comfortable for patients and provides dynamic, real-time assessments (Ferri et al, 2005;Khoury et al, 2007). Dynamic assessments are especially useful during superior acromioclavicular ligament; cla, clavicle; lat, lateral; med, medial; sk, skin layer; SupraS, supraspinatus; 1-3, the deep joint space distance; 2-4, the capsule displacement.…”

The acromioclavicular joint (ACJ) is a common source of pain and disability. Several provocative tests are used to diagnose ACJ lesions. The aim of this study was to evaluate anatomic changes of the ACJ using dynamic ultrasonography during provocative tests. Eighty ACJs of 40 healthy volunteers were subjected to dynamic ultrasonographic examinations. Examinations were performed in a resting position and during passive external rotation, cross body adduction, and active compression testing. Deep joint space distance and capsule displacement were measured ultrasonographically. Mean deep joint space distances during cross body adduction (6.4 +/- 1.6 mm) and active compression (6.6 +/- 1.8 mm) testing were significantly smaller than during passive external rotation testing (7.7 +/- 1.7 mm, P < 0.01) or rest (8.1 +/- 1.8 mm, P < 0.01). Mean capsule displacements during active compression (3.5 +/- 0.8 mm) and cross body adduction (3.4 +/- 0.7 mm) testing were significantly greater than those during passive external rotation testing (2.9 +/- 0.7 mm, P < 0.01) or rest (2.5 +/- 0.7 mm, P < 0.01). Dynamic ultrasonography revealed that the cross body adduction and active compression tests applied more stress to the ACJ than the passive external rotation test, which suggests that these two tests are likely to be more useful provocative tests for the diagnosis of ACJ lesions. Furthermore, the dynamic properties of ultrasonography could be used to estimate the suitability and validity of provocative tests in other musculoskeletal diseases.
