Cortical and Trabecular Bone

  • Jenifer Jowsey
Part of the Topics in Bone and Mineral Disorders book series (TBMD)


Eighty percent of the skeleton consists of cortical bone, while twenty percent is trabecular; the percentages are of the wet or dry weight of the bone and do not include the soft-tissue or marrow spaces that make up part of the bone, particularly the trabecular or spongy bone. Evaluation of skeletal status, therefore, should be made on samples of bone in which the two types are present in approximately these two proportions. The majority of bone biopsy procedures include only trabecular bone and for this reason the quantitative results must be expected to be different from analyses which include both cortical and trabecular bone.
