Bone Growth and Fracture Healing Flashcards
1
Q
What are some of the traits of cortical bone?
A
Found in the Diaphysis.
Resists bending and torsion.
Laid down circumferentially.
Less biologically active
2
Q
What are some of the traits of cancellous bone?
A
Found in the metaphysis.
Resists/absorbs compression.
Site of longitudinal growth.
Very biologically active.
3
Q
What occurs in the first stage of fracture healing?
A
Mainly inflammation.
Haematoma and fibrin clot.
Angiogenesis.
4
Q
What occurs in the 2nd stage of fracture healing?
A
Begins when inflamation has subsided.
Lays down a soft callus
Angiogenesis still continues.
5
Q
What occurs during the 3rd stage of fracture healing?
A
Conversion of cartilage to woven bone.
Hard callus is laid down.
