The change of bone density in five patients with solitary bone cysts (SBC) was directly measured by microdensitometry (MD). Standard plain radiographs could not always predict the strength of the bone, but with MD, smaller changes in bone density could be found quantitatively. The density of the lesion temporarily decreased just after steroid injection and began to increase to maximum level in approximately 4 or 5 months. However, in two patients, the density decreased gradually to the first MD levels and refractured. In this article we stress the usefulness of direct MD in detecting the strength of the lesion.
通过显微密度测定法（MD）直接测量了5例孤立性骨囊肿（SBC）患者的骨密度变化。标准平片并不总能预测骨强度，但采用MD可以定量发现骨密度的较小变化。类固醇注射后病变密度暂时降低，约4或5个月后开始增加至最高水平。然而，有2例患者，密度逐渐降至最初的MD水平并再次骨折。在本文中，我们强调直接MD在检测病变强度方面的实用性。
