A 6-year-old boy presented with the recent development of a right sided limp. He had no known medical conditions. On examination, the patient had limited internal/external rotation and abduction of the right hip. He walked with a non-antalgic gait and was noted to have a positive Trendelenberg sign. Lower extremity radiographs (A) revealed flattening of the right proximal femoral epiphysis with...

Introduction Hip arthrography is considered of importance in tailoring treatment in children with LCPD [l-3]. Hip arthrography in children with LCPD is employed for dynamic imaging to determine congruency and containment of the femoral head by the acetabulum as well as to rule out “hinge abduction” [3]. Information obtained by hip arthrography may help in selecting candidates for operative trea...

PURPOSE Patients who have secondary hip osteoarthritis as sequelae of Legg-Calvé-Perthes disease (LCPD) are severe deformities of femoral head and acetabulum. A few studies have presented that the clinical results and risks associated with total hip arthroplasty (THA) for patients with a history of LCPD were not satisfactory. In this study, we reported the radiographic and clinical outcomes of ...
