QuestionChoice
This describes the formation of granulation tissue which occurs days to weeks after the initial injury

c
Mesenchymal cells and inflammatory cells are recruited to the fracture site and form fibrin-rich granulation tissue which provides provisional stability
QuestionChoice
Hard callus formation describes the calcification of the soft callus. This occurs weeks after the initial injury

a
Endochondral ossification results in the calcification of a cartilaginous callus
QuestionChoice
This describes soft callous formation which occurs before hard callus formation

d
Mesenchymal cells differentiate resulting in chondrogenesis and a fibrocartilaginous network connecting the fracture ends
QuestionChoice
This describes bone remodelling of the hard callus and occurs weeks to months after the initial injury
10026872
b
Osteoclast and osteoblast activity leads to the formation of compact bone at the callus centre and lamellar bone at the callus edges
QuestionChoice
This occurs immediately after the initial injury due to disruption of blood vessels surrounding the fracture
