Legg-Calve-Perthes disease is one of the most severe and common diseases of the hip joint in children aged 2 to 14 years, which can lead to juvenile coxarthrosis. Etiology is considered to be multifactorial and caused by a combi-nation of genetics factors with internal and environmental. Regardless of the cau-ses of LCPD, the interruption of blood supply at its level represents the main pathogenetic moment that triggers pathological changes. There is still no definite diagnostic algorithm for the detection of LCPD at an early stage - the fact that leads to the late diagnosis of idiopathic avascular necrosis. And the development of an optimal complex for the multilateral treatment of Legg-Calve-Perthes disease is a current task of modern studies.
