Age dependent ultrasound B-mode findings of the elbow joint in healthy children and adolescents.

Due to maturation of joints, various changes take place, not only in the field of paediatric rheumatology but also in paediatric orthopaedics musculoskeletal ultrasound plays an important role in both the diagnosis and the follow-up of diseases in this field. To differentiate between physiological and pathological findings, the knowledge of reference values of joint structures is indispensable. The objective was to define B-mode ultrasound age- and sex-related reference values for the elbow joint in healthy children and adolescents during maturation.

Arthrosonographic Reference Values of the Shoulder Joint in Healthy Children and Adolescents: A Cross-Sectional Multicentre Ultrasound Study.

Unlabelled: Defining of gray scale ultrasound standard reference values of the shoulder joint in childhood and adolescence during maturation.

Patients: We examined 445 healthy girls and boys between 1 year and 18 years of age. A cross-sectional multicentre grey-scale ultrasound study was performed to examine the shoulder joint on both sides.

Pediatric musculoskeletal ultrasound: age- and sex-related normal B-mode findings of the knee.

Musculoskeletal ultrasound (MSUS) is an important tool for evaluating disease activity, therapeutic progress, and remission status of rheumatic diseases in children. Knowledge of age-related normal findings is essential when interpreting pathological findings such as those seen in juvenile idiopathic arthritis. To evaluate normal findings of the knee joint, we recorded age-related stages of musculoskeletal development in the knee of 435 healthy children between 1 and 18 years of age using high-resolution B-mode MSUS.
