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.
成人特发性股骨头坏死约占所有退行性髋关节疾病病例的2%至3%。股骨头塌陷的晚期坏死给年轻患者带来了棘手的治疗难题。因此，早期影像学诊断至关重要。对100例特发性股骨头坏死患者的典型早期影像学表现进行了研究。这些表现包括股骨头与颈部交界处的硬化区域，以及颈部下缘的骨膜反应。讨论了这些变化与机械应力和血液供应不足的关系。更晚期坏死的征象是分界点处的带状硬化和股骨头软骨下脱钙。识别早期影像学特征可提高成功治疗的几率，尤其是在低年龄组。
