The bone mineral content of 109 lumbar vertebrae from 36 different subjects was determined by dual photon absorptiometry. The mean age of the subjects was 58.5 years (range, 31 to 79 years). The ultimate strength of the vertebral bodies was determined during axial compression. Bone mineral content and ultimate compressive strength were correlated (r = 0.86) and the strength was found to increase linearly with increasing amounts of bone mineral content. No differences in this correlation were found in the four vertebral levels (L-4) included in the study, but a difference in this correlation was found between specimens taken from male and female subjects. The results make it possible to estimate the strength of a vertebral body from the knowledge of its bone mineral content as determined by dual photon absorptiometry and provide a basis of estimations of normal and abnormal amounts of bone mineral content in the vertebrae of the lumbar spine.
通过双能光子吸收法测定了36名不同受试者的109块腰椎椎体的骨矿物质含量。受试者的平均年龄为58.5岁（范围为31至79岁）。在轴向压缩过程中测定椎体的极限强度。骨矿物质含量与极限抗压强度相关（r = 0.86），并且发现强度随骨矿物质含量的增加而呈线性增加。在该研究纳入的四个椎体水平（L-4）中未发现这种相关性存在差异，但在取自男性和女性受试者的标本之间发现了这种相关性的差异。这些结果使得根据双能光子吸收法测定的骨矿物质含量来估计椎体强度成为可能，并为估计腰椎椎体正常和异常骨矿物质含量提供了依据。
