The material properties of immature bone.
The age-related material properties of developing immature canine bone were determined for the femora, tibiae, humeri, radii, and ulnae in animals from 1 wk of age to maturity. These properties included bone geometry changes, material tissue properties, and qualitative and quantitative morphological evaluations. All bones exhibited a two-phase growth cycle, an initial rapid phase (20 wk) followed by a substantially slower growth to maturation (48 wk). All properties showed age-related changes except bone tissue strain to failure.
