The broken bone fragments resulting from the fracture are able to absorb themselves. Throughout the fracture process, the eventual tendency of all bone scabs is to encircle the fracture break and cause the fracture line to gradually blur and disappear through the deposition of bone. During this process, the bone scab can encircle the fragmented bone fragments together, even though a small portion, due to the relatively distant drift of the fragmented bone fragments, can still be gradually absorbed through a period of sculptural remodeling. This process lasts for a relatively long time, up to about 2 years after the fracture has healed. After the fracture is put under weight, the fractured end will be strengthened due to the stimulation of gravity, and the unimportant part of the bone scab that is not normally used will be gradually absorbed, including the fragmented bone pieces and fragmented bone fragments.
