A study of the thickness and spacing of bony structures in the cancellous bone of the iliac crest. Ground sections of methacrylate-embedded material from 67 normal subjects, from 20 to 90 years of age, were examined. Increasing age is accompanied by an increase in the spacing between the bony structures, but not by any significant reduction in their thickness. The thinnest bony structures appear to be undergoing the most remodelling, as judged by the extent of formation and resorption surfaces.
