[Rheumatic shoulder joints in childhood].

Although the knee joint in children and adolescents is most frequently affected in cases of juvenile idiopathic arthritis (JIA), shoulder joint arthritis is only present in a small proportion of JIA patients at disease onset. Shoulder joint involvement is more frequently seen in polyarthritis or chronic JIA, which if not considered and left untreated can lead to substantial joint immobility and with a destructive course. In addition to the clinical examination, imaging methods help to verify an early involvement of the shoulder joint and imaging can also provide important information in a treat to target concept. The treatment of pediatric omarthritis is very often guided by the treatment algorithm for the appropriate JIA category. In this respect, in addition to local steroid injections, medications such as methotrexate, biologicals and also Janus kinase (JAK) inhibitors are used. In addition to the pharmacotherapy, physiotherapy also plays an important role.
