Explanation: 

Detailed explanation-1: -Fractures heal by forming callus, which follows three overlapping phases: inflammatory, reparative and remodelling.

Detailed explanation-2: -Following the fracture, secondary healing begins, which consists of four steps: Hematoma formation. Fibrocartilaginous callus formation. Bony callus formation.

Detailed explanation-3: -First, inflammation occurs after the injury. Then the bone is induced to repair and is forming soft callus. At the third step the bone gets stronger and forms hard callus. At the last step, the new compact bone is formed and blood vessels regenerate.

Detailed explanation-4: -Inflammatory Phase An inflammatory response occurs immediately following bone fracture. The trauma leads to blood vessel rupture inside and surrounding the fracture site, resulting in a hematoma.

Detailed explanation-5: -Five Stages of Healing a Fracture. First stage: Hematoma formation. Second stage: Development of fibrocartilaginous callus. Third Stage: Development of bony calluses. Fourth Stage: Bone remodeling. Fifth Stage: Bone support and recovery. 21-Jan-2023
