There are four stages in the healing of a bone fracture. Which of the following best illustrates the sequence of these stages: 1. bony callus
formation 2. bone remodeling 3. fibrocartilage callus formation 4.
hematoma formation
0 4,3,1,2
1,3,4,2
1,3,2,4
4,3,2,1
1,2,3,4

4,3,1,2

Explanation:

The first stage is the bodies reaction to injury. The hematoma formation stops internal bleeding from the broken blood vessels of the fractured/broken bone.  

The fibrocartilage callus formation helps maintain the bones original form, helping in the overall healing process.

The bony callus is the hardening of the cartilage callus, and the final form remodels the bone to be as closely recovered as its original form

the answer should be true
