 BONE(FRACTURE)HEALING PROCESS***

√It has 6 phases
1.Hematoma formation
2.Granulation Tissue formation.
3.Callus formation
4.Ossification
5.Consolidation
6.Remodelling.

1.HEMATOMA FORMATION**
√Following a fracture,,There is injury to the surrounding tissue by the broken bones.
√The blood accumulates and become solid and this is what is called a Hematoma.

2.GRANULATION TISSUE FORMATION**
√During this stage,The formed hematoma changes into a new tissue called granulation tissue
√Granulation tissue contains new blood vessels,fibroblasts,and Osteoblasts.
√ A new bone called Oesteoid is eventually formed.

3.CALLUS FORMATION**
√After the Osteoid is formed,minerals are deposited in it forming a bone called Callus.
√Callus rounds the fracture site.
√It contains cartilage,oesteoblasts,calcium and phosphorus.

4.OSSIFICATION**
√Ossification is bone formation or growth.
√After callus formation,bone formation continues until fracture has healed.
√The bone is sufficient to prevent any movements at fracture site.

5.CONSOLIDATION**
√ The callus continues to grow and covers all the space between the bone fragments.
6.REMODELLING**
√During this stage,Union is complete.
√The bone returns its pre injury or normal shape and size.
√Bone is able to withstand weight bearing.
