Diagnosis of hip joint pathology remains a serious problem in childhood and adolescence. A wide range of pathologiesincluding dysplastic, dystrophic, inflammatory, oncological and post-traumatic diseases of the musculoskeletal system-leads to the advancement of imaging methods and techniques. Legg-Calve-Perthes disease (LCPD) is a common cause of hip pain in children that may be initially clinically and radiographically difficult to diagnose Radiography of the pelvis in two views (anteroposterior and Lauenstein) is the main method of diagnosing aseptic necrosis. Destructive changes of the femoral head and neck of the femur are clearly determined. However, the presence of X-ray negative patterns at the first stage of the disease and the impossibility of visualizing all the anatomical structures induce us to improve the diagnostic algorithm of this difficult pathological process.
