Ultrasonography of the painful hip in childhood

Abstract

There are many diseases in childhood that affect the hip joint. Some diseases are systemic in origin and initially may present themselves as hip disorders, such as rheumatoid arthritis. other diseases are localized specifically in the hip joint, such as transient synovitis and Perthes' disease, mostly unilateral. Neoplastic or infectious diseases around the hip joint may also manifest themselves as a painful hip. If both hips are affected the differential diagnosis should include skeletal dysplasias (multiple epiphyseal dysplasia) and metabolic diseases (hypothyroidism, Gaucher's disease, mucopolysaccharidoses and mucolipidoses)
