Bone Fracture and Repair

Front

What is the role of mechanical stress in bone remodeling?

Back

Mechanical stress helps replace spongy bone with compact bone during the bone remodeling phase.

Front

What stage of bone healing resembles the original unbroken bone?

Back

The remodeling stage of bone healing resembles the original unbroken bone.

Front

What are bone-forming cells called?

Back

Bone-forming cells are called osteoblasts.

Front

What is a fracture hematoma?

Back

A fracture hematoma is a blood clot that forms within 6-8 hours after a bone breaks, due to broken blood vessels.

Front

What acts as the body’s natural splint during bone healing?

Back

The fibrocartilaginous callus formation acts as the body’s natural splint.

Front

What is the first stage of bone healing?

Back

The first stage of bone healing is hematoma formation.

Front

What is the function of osteoclasts?

Back

Osteoclasts are cells that break down bone tissue.

Front

What is the significance of the bony callus formation stage?

Back

The bony callus formation stage is significant as it replaces the fibrocartilaginous callus with a hard bony callus.

Front

How long does the remodeling phase of bone healing last?

Back

The remodeling phase can last for several months to years, depending on the severity of the fracture.

Front

What is the difference between osteoblasts and osteocytes?

Back

Osteoblasts are bone-forming cells, while osteocytes are mature bone cells that maintain bone tissue.
