title: [The asterisk sign and adult ischemic femur head necrosis].
abstract: The asterisk sign is a stellate density, which is seen normally in the femoral head on computed tomography. It is due to the demonstration of the trabeculae in the femoral head. In adult ischaemic necrosis of the femoral head, there are characteristic changes in the asterisk sign at an early stage, even before there is collapse of the head. The changes are described and the indications for performing CT of the hip for diagnosing adult ischaemic necrosis are discussed.
