Children with femoral head radiographic changes suggestive of bilateral avascular necrosis require a careful differential diagnosis. Although the child may be found to have an epiphyseal dysplasia, the course may not be benign. At adolescence, in certain of the multiple epiphyseal dysplasia tarda forms, rapid destruction of the femoral head occurs with clinical and radiographic features indistinguishable from avascular necrosis. A possible interrelationship between epiphyseal dysplasia and avascular necrosis is considered.
股骨头X线片有双侧缺血性坏死改变的儿童需要进行仔细的鉴别诊断。虽然患儿可能被诊断为骨骺发育异常，但其病程可能并非良性。在青春期，某些迟发性多发性骨骺发育异常类型中，股骨头会迅速遭到破坏，其临床和X线特征与缺血性坏死难以区分。骨骺发育异常与缺血性坏死之间可能存在某种相互关系。
