Abstract

Introduction and synopsis Superficially, bones look fairly solid. But looks are deceptive. Most bones are an elaborate construction, made up of an outer shell of dense compact bone, enclosing a core of porous cellular, cancellous, or trabecular bone (trabecula means ‘little beam’ in Latin). Examples are shown in Fig. II.I: cross-sections of a femur, a tibia, and a vertebra. In some instances (as at joints between vertebrae or at the ends of the long bones) this configuration minimizes the weight of bone while still providing a large bearing area, a design which reduces the bearing stresses at the joint. In others (as in the vault of the skull or the iliac crest) it forms a low weight sandwich shell like those analysed in Chapter 9. In either case the presence of the cancellous bone reduces the weight while still meeting its primary mechanical function. An understanding of the mechanical behaviour of cancellous bone has relevance for several biomedical applications. In elderly patients with osteoporosis the mass of bone in the body decreases over time to such an extent that fractures can occur under loads that, in healthy people, would be considered normal. Such fractures are common in the vertebrae, hip and wrist, and are due in part to a reduction in the amount of cancellous bone in these areas. The degree of bone loss in a patient can be measured using non-invasive techniques, so an understanding of the relationship between bone density and strength helps in predicting when the risk of a fracture has become high.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
