    Notes: Abstract. Ossicles located in the acetabular fossa may confuse diagnostic and therapeutic work-up. An accessory ossification centre may persist unfused as an os acetabuli centrale which is surrounded by intact hyaline cartilage representing an anatomic variant. Bone islands located in the pillars of the acetabulum can project into the acetabular fossa simulating acetabular ossicles. Osteochondrosis dissecans, posttraumatic articular bodies, degenerative disease and other rare lesions may be responsible for clinical symptoms and are of similar appearance than anatomic variants. Plain film radiography, X-ray tomography, CT and MRI are used to categorize these lesions. MRI is very valuable to assess cartilage integrity in a noninvasive way, but arthro-CT or arthro-MRI have to be used in unclear cases. Therefore the purpose of this presentation is to discuss the appearance, the possible etiology and the differential diagnosis of acetabular ossicles and how they can be evaluated to avoid an unnecessary arthrotomy.

    Description / Table of Contents: Summary Sonography of the shoulder joint is a well-established technique in the hands of the experienced examiner, when using a standardized protocol. It has proved invaluable in assessing pathological soft tissue changes, especially after trauma. The static evaluation of anatomy and dynamic assessment of function are especially helpful in both preoperative staging and postoperative follow-up. The normal anatomy, examination techniques, including our own variations, and pathological conditions are discussed. The findings and various classifications of impingement syndrome, rotator cuff injuries, biceps tendon lesions and inflammatory changes are examined. Review of the major articles in the literature shows excellent correlation with our results, the overall sensitivity in the case of rotator cuff lesions being over 90 %. A well-performed ultrasound examination in most cases obviates the need for the more invasive arthroscopy and the more cumbersome and expensive MRI examinations.
    Notes: Zusammenfassung Der Stellenwert der Schultersonographie unter standardisierten Untersuchungsbedingungen und entsprechender Erfahrung des Untersuchers ist unbestritten. Insbesondere im Bereich der Traumatologie ist die Wertigkeit bei Rotatorenmanschettenläsionen mit entsprechendem operativem Korrelat statistisch gut abgesichert. Die Overall-Sensitivität bei Rotatorenläsion liegt heute bei ca. 95 %. Partielle und Totalrupturen der Rotatorenmanschette sowie das Impingementsyndrom fallen unter den Sammelbegriff Subakromialsyndrome und sind sonographisch sowohl in statistischer als auch dynamischer Untersuchungstechnik gut beurteilbar. Eine wesentliche Bedeutung hat die sonographische Normalwertbestimmung von Schulterweichteilen als metrisches Fundament zur Bewertung pathologischer Veränderungen. Ein definiertes Staging (prä- wie postoperativ) ermöglicht eine exakte Operationsplanung sowie eine genaue Therapiekontrolle. Die Beurteilung der Gleitlager als indirekter Hinweis auf Traumen bzw. bei entsprechender Klinik als Anhaltspunkt entzündlicher Veränderungen mit exsudativ proliferativen Gelenkergüssen oder im Rahmen der Tendinitis calcarea ist heute sonographischer Untersuchungsstandard. Die Indikation für andere Untersuchungsverfahren wie Arthroskopie, Kontrast-CT oder MRT ist dadurch zurückgedrängt.
