[Coxalgia in adolescents: apropos of three different cases: chondrolysis, transient osteoporosis and epiphyseolysis].

We report 3 adolescents presenting with hip pain. Idiopathic chondrolysis, transient osteoporosis and slipped epiphisis were the final diagnosis. Initial diagnosis may be difficult despite adequate investigation. In such cases long-term follow-up is essential. This paper includes a differential diagnosis of hip problems in childhood.
