After prolonged heavy metal exposure (e.g., lead) "lead bands" develop at the metaphyseal ends of growing bones. These "lead bands," while a constant finding, are used as additional laboratory evidence to diagnose plumbism. In this study, the role of the proximal fibula in distinguishing physiologic sclerosis from pathologic thickening of the zone of provisional calcification is assessed. In addition, laboratory values are compared to radiographic findings in a controlled fashion to establish levels at which "lead bands" appear. The former is a useful adjunct in the radiographic diagnosis of plumbism, while the minimum blood levels at which "lead bands" are seen is much lower than previously described.
长期暴露于重金属（如铅）后，在正在生长的骨骼的干骺端会形成“铅带”。这些“铅带”虽然是一个常见的发现，但可作为诊断铅中毒的额外实验室证据。在本研究中，评估了近端腓骨在区分生理性硬化与临时钙化区病理性增厚方面的作用。此外，以可控方式将实验室值与影像学结果进行比较，以确定“铅带”出现时的水平。前者是铅中毒影像学诊断的有用辅助手段，而出现“铅带”时的最低血铅水平比之前描述的要低得多。
