Answer:
The sequence that best represents the order during repaid of a fracture as as
follows
3. hematoma formation
4. fibrocartilaginous callus formation
2. bony callus formation
1. cartilage ossification
5. remodeling of woven (spongy) bone into compact bone
Explanation:
When a bone is fractured, the first step following a bone fracture is hematoma formation.
Hematoma formation is formed when a little blood escapes from the blood vessels and remains in the skin's thickness, creating a blue spot. The hematoma is an effusion of blood that occurs deeper under the skin.
From there, the formation of tissues begins from end to end of the broken bones. It is a reorganization of the bone tissue (the bone itself), allowing the consolidation of a fractured bone. This bone formation welds the two parts of the broken bone together for a particular period depending on the patient's bone tissue condition. This bone callus will form in two episodes.
1) There first appears a fibrocartilaginous callus, also called connective callus, which allows the fracture to heal in a few weeks. It is an immature bone.
2) In a second step, this immature bone is gradually replaced by another bone (calcified/bony) resembling the bone which has been fractured.
From there, the ossification of the callus occurs where the bony callus is further replaced by woven spongy bones to form a stronger stabilizing collar.
Finally, the remodeling of woven (spongy) bone into compact bone takes place. Lamellar bones are replacing these woven spongy bones.
