Okay, so during a repair of a bone fracture multiple steps occur.
00:05
So first step would be that the hematoma, so the hematoma it would basically fill the gap, fill gaps between the bone fragments, bone fragments.
00:21
Now this is which option? this is option number two.
00:25
So blood vessels are damaged, so blood vessels get damaged when there is any fracture and this will lead to bleeding at the site of fracture and it would result in a formation of this blood clot and it is known as the hematoma, hematoma.
00:47
Now this hematoma it would fill the gap, fill gap between these fragments.
00:54
Second would be the statement number fourth, so which says that the fibroblast, so fibroblast and the chondroblast, so fibroblast and the chondroblast these are two type of cell.
01:09
Now these would basically infiltrate, so these will infiltrate the hematoma, hematoma.
01:19
Now hematoma is relatively a soft callus form, so soft callus is formed and what happens is these cells they are specialized in the tissue repair.
01:35
So they would start with the tissue repair and they would basically migrate into the hematoma for the repair and prepare the soft callus and this would stabilize the, so it would stabilize the fracture site to provide a healing.
01:53
Next step would be the statement number three which is says that the osteoblast, so there is this osteoblast, they would build a new born callus...
