title: [Aseptic necrosis of the femur head in congenital hip dysplasia. Radiological signs for a prediction or an early diagnosis (author's transl)].
abstract: Radiographs an patient histories of 36 children were examined in order to determine radiological signs that would allow a prediction or an early diagnosis of the aseptic necrosis of the femur head nucleus (Luxations-Perthes) during the treatment of hip dysplasia. Necrosis of the nucleus appeared in 17 joints (of 15 children). We had the following findings: a) Mikroepiphyses have a high risk (59%). b) In all cases of necrosis the angles of the femur neck near epiphysis were rounded, while this sign was never found in dysplastic joints without necrosis.
