There are three steps in fracture healing:

1.Inflammation

2.Repair

3.Remodeling

1.Inflammation: Hematones appear at the site and forms hemotocytes. Granula tissue formation.

2. Repair:  a).soft callus: At the site of fracture a cartilage forms which serves as a bridging bone.

                 b).hard callus: the callus is replaced by the immature bone.

3. Remodeling: The osteoblats forms the site and replaces the immature with the hard bone.
