Accumulation of Microdamage With Increasing Strain in Bovine Trabecular Bone


 Microcracks are present in normal human bone, and microcracks are thought to be a stimulus for bone remodeling. When there is an imbalance between microcrack creation and repair, microdamage can accumulate and result in bone fracture.
 Seventeen specimens were tested in monotonic compression to one of six total strain levels. Chelating fluorochromes were used to label cracks and distinguish between microdamage created before and during testing. Histology specimens were observed under epifluorescence for microdamage in the form of microcracks. The number of cracks, sum of the crack lengths, and frequency distribution were recorded for each specimen. Microdamage accumulated non-linearly with increasing total strain on the specimen, but the mean crack length remained the same with increasing damage.
