Questions and Answers
What is hematoma formation?
What is hematoma formation?
- Blood vessels are ruptured when the bone breaks (correct)
- Formation of blood vessels
- Reformation of bone cells
- Formation of a strong permanent patch
What happens during fibrocartilage callus formation?
What happens during fibrocartilage callus formation?
The break is splinted by fibrocartilage callus, new capillaries grow, and dead tissues are disposed of by phagocytes.
What characterizes bony callus formation?
What characterizes bony callus formation?
Osteoblasts and osteoclasts migrate into the area, and fibrocartilage is replaced by spongy bone.
What is the process of bone remodeling?
What is the process of bone remodeling?
Study Notes
Fracture Healing Steps
-
Hematoma Formation: Blood vessels rupture during a bone fracture, leading to blood-filled swelling; this swelling denies nutrients to bone cells, resulting in cell death.
-
Fibrocartilage Callus Formation: The fracture is stabilized by a fibrocartilage callus; new capillaries grow and phagocytes clear away dead tissue, forming a connective tissue repair scaffold.
-
Bony Callus Formation: Osteoblasts and osteoclasts move into the fracture area where they proliferate; the fibrocartilage is replaced by a spongy bone callus known as the bony callus.
-
Bone Remodeling: The bony callus undergoes remodeling in response to mechanical stress, leading to the formation of a strong, permanent repair at the fracture site.

Description
Explore the intricate process of fracture healing through its four essential stages: hematoma formation, fibrocartilage callus formation, bony callus formation, and bone remodeling. This quiz will test your understanding of how bones repair themselves after a fracture and the cellular processes involved.
