©2013 UpToDate ® Print Email Age-related loss of trabecular bone Sequential trabecular loss as shown by histologic examination of bone specimens; the vertical trabeculae are shown in yellow, the horizontal in blue-green. First panel: Normal 50-year-old man with an almost perfect continuous trabecular network. Second panel: 58-year-old man with thinning of the horizontal trabeculae and some loss of continuity. Third panel: 76-year-old man with continued thinning of the horizontal trabeculae and wider separation of the vertical structures. Fourth panel: 87-year-old woman with advanced breakdown of the entire network showing unsupported vertical trabeculae. The third and fourth panels represent the degree of loss of bone mass and microarchitectural deterioration that is generally defined as osteoporosis. From Mosekilde, LI, Bone 1988; 9:247.
