A comminuted fracture of the heel bone will basically return to the level required for normal life after one year. The main function of the heel bone is the function of standing and walking, and if a comminuted fracture of the heel bone will seriously affect the ability to walk. Generally, the healing of the fracture will go through the hematoma inflammation mechanization period (about 2 weeks), the original bone scab formation period (3~6 months), and the bone scab remodeling and shaping period (about 1~2 years). Therefore, one year after the comminuted fracture of the heel bone, the fracture is in the period of scab remodeling and shaping. At this time, the generated bone scab is constantly remodeling and reinforcing under the action of stress. At this time, the fracture is basically recovered to fulfill the function required for daily life. However, it takes 1~2 years for the fracture to fully recover, and when it passes through the scab remodeling and shaping period completely, the fracture will leave no traces on histology and imaging.
