title: [The early radiological findings of idiopathic necrosis of the femoral head in adults (author's transl)].
abstract: Idiopathic necrosis of the femoral head in adults occurs in about 2 to 3% of all cases of degenerative hip disease. Advanced necrosis with collapse of the head offers a difficult therapeutic problem in younger patients. Early radiological diagnosis is therefore important. The typical, early radiological findings were studied in a hundred patients with idiopathic necrosis of the femoral head. They consist of an area of sclerosis at the junction of the head and neck, with a periosteal response on the inferior margin of the neck. The relationship of these changes with mechanical stress and defective blood supply is discussed. Signs of more advanced necrosis are band-like sclerosis at the point of demarkation and sub-chondral decalcification of the femoral head. Recognition of the early radiological features improves the chances of successful treatment, particularly in the lower age group.
