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 remodeling phase.

Front

What is a greenstick fracture?

Back

A greenstick fracture is an incomplete fracture usually seen in children, where the bone bends and cracks on one side without breaking completely.

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 replaces the fibrocartilage callus during fracture repair?

Back

The fibrocartilage callus is replaced with spongy bone during the fracture repair process.

Front

What are osteoclasts?

Back

Osteoclasts are cells responsible for cleaning up pieces of bone following a bone fracture.

Front

What is the first step in the bone healing process?

Back

The first step in the bone healing process is the formation of a fracture hematoma.

Front

What type of fracture is characterized by a break that goes completely through the bone?

Back

A complete fracture is characterized by a break that goes completely through the bone.

Front

What is the function of osteoblasts in bone repair?

Back

Osteoblasts are responsible for forming new bone tissue during the repair process.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bone, while spongy bone is lighter, less dense, and found inside bones.

Front

What is the role of collagen in bone healing?

Back

Collagen provides a scaffold for new bone formation and helps in the healing process.
