In children, the association of traumatic luxation of the hip with homo- and heterolateral fracture of the upper extremity of both femurs, is extremely rare. In the case reported here, that association is present. Hip luxation can easily pass unrecognized. Orthopedic reduction is always recommended. Regarding the fracture of the upper portion of the femur in children under 10 years, when alignment of the fragments is not well achieved, surgical treatment should be considered. In this case, valgus osteotomy had to be performed in order to correct a post-traumatic coxa vara. After 4 1/2 years of follow up, the only sequel was a 1 cm leg-length discrepancy.
