Healing of Bones in Fractures

Healing of Bones in fracture :
It involves three phases, viz.,
1. Inflammatory phase 2. Reparative phase and 3. Remodelling phase
1. Inflammatory Phase : - When a fracture occurs, at the site of fracture
the blood vessels get broken and the blood fills up the gap of the bone.
This blood clots to form a haematoma. This process takes place in one to
two days. The soft tissue of this region undergoes inflammation.
2. Repairative Phase : - A stage of callus is formed. It bridges the gap and
establishes contact between the ends of fractured bone. The callus is
nothing but granulation of tissues around the site of fracture. This phase
takes place about eight to twelve weeks.
3. Remodelling phase : - Once the fracture is bridged by the callus tissue,
the site of fracture undergoes remodelling by muscular and weight bearing
stresses and slight deformity gets corrected by moulding. This remodelling
takes up to one year.
