“…However, MRI has been previously used to determine the muscle quality of the rotator cuff [15,27,28]. In a prospective study on 38 patients, Gladstone et al assessed the fatty infiltration of the rotator cuff before and after surgical repair [29].…”

Purpose Muscle atrophy is a commonly encountered problem in osteoarthritis (OA). The aim of this study was to estimate the amount of muscle atrophy and fatty degeneration of the lower leg muscles related to ankle OA by magnetic resonance imaging (MRI). Methods Twenty-one patients with unilateral ankle OA were included in this cohort study. Calf circumference of the affected and healthy lower leg was documented. The degree of OA was classified in conventional radiographs. The cross-sectional areas and fatty degeneration of the muscles of the lower leg were measured in bilateral MRI.

“…Ultrasound (US) is a valuable imaging technique for displaying abnormalities of the ACJ with dynamic evaluation in the form of the cross-arm maneuvre being suitable for the detection of mild or moderate sprains in AC separation [12, 15]. Although the direct sonographic visualization of the ACJ is a very sensitive imaging modality considering vertical instability, a standardized dynamic examination of the horizontal instability using ultrasound has not been described [5–7, 12, 14].…”

Summary Background Horizontal instability influences the clinical outcome after acromioclavicular joint (ACJ) injuries and in joint degeneration. A standardized, dynamic examination of the horizontal instability has not been described before. This current study presents a sonographic method to analyze the dynamics between the clavicle and acromion in the horizontal plane. Methods The horizontal joint play, the ACJ space and the offset between clavicle and acromion were sonographically assessed by a 45° ventrally angulated longitudinal section. A total of four investigators with different experience in the field of musculoskeletal ultrasound examining 20 ACJs in 10 human cadavers. Measurements in the absence of any pressure and under standardized anterior and posterior pressure onto the clavicle were carried out in different ligament status intact acromioclavicular (AC) and coracoclavicular (CC) ligaments as well as in a Rockwood (RW) II and III model. A two-sided t‑test was used to examine the differences between joint positions and ligament status. Results The horizontal joint play was 1.3 ± 0.9 mm with intact ligaments, 1.4 ± 1.2 mm by transecting the AC ligaments and 1.9 ± 1.3 mm after additionally transecting the CC ligament. The joint space was 3.3 ± 1.1 mm with intact ligaments, 4.1 ± 1.8 mm in an iatrogenic RW 2 injury, and 5.3 ± 3.3 mm in an iatrogenic RW 3 injury. Manipulating the clavicle by applying anterior or posterior pressure did not change the difference within one injury pattern. Interobserver reliability was 83.9%. Conclusion Apart from evaluating the ligaments and the joint capsule, measurement of the dynamic horizontal instability is possible in a human cadaver model. The ultrasound-based measurement of horizontal instability dynamics avoids radiation exposure, is readily available and cost-efficient.

“…Die Sonographie des Schultergelenkes ist eine sichere Methode in der Primärdiagnostik einer RM-Läsion. Die Sensitivität und Spezifität der sonographischen Untersuchung ist insbesondere bei transmuralen Läsionen ähnlich hoch wie die der MRT-Untersuchung [32] -allerdings auch von der Erfahrung der Untersucher abhängig [23], und die objektive Verwertbarkeit für die Begutachtung ist von standardisierten Schnitteinstellungen und verwertbaren Bilddokumenten abhängig [22]. Neben der Sonographie ist v. a. die MRT-Bildgebung eine wichtige Methode, um eine RM-Läsion zu diagnostizieren und Pro-und Kontrakriterien für eine traumatische oder degenerative Genese der Läsion festzuhalten.…”
