Abstract

This work aims to explain the behavior of cracks in bones because the bone repairing mechanism is still somehow unknown. In this matter, different issues exist, such as the biological parameters (e.g., osteoblasts and osteoclasts), and the physical parameters (e.g., microcracks and defects). Traditionally, the bones respond to any load or defect within their microstructures. The defects and microcracks are increasing in the aged bone. Therefore, the damage increases unless the remodeling is completed. Remolded bones have increased fracture toughness. Hence, it is a basic mechanism for repair based on Wolff’s law. The smaller crack lengths (e.g., less than 1 µm) are subjected faster to the repair process due to their intrinsic conditions like remodeling, plasticity, and bridging. The extension of the crack around the osteon and fiber bridging will increase the bone’s toughness. In this work, the schematic conclusions have been presented.
