Bone Fracture and Repair

Front

What is the name of the incomplete fracture usually seen in children?

Back

Greenstick fracture is a type of incomplete fracture where the bone bends and cracks on one side without breaking completely, commonly seen in children due to their softer bones.

Front

What cells are responsible for cleaning up pieces of bone following a bone fracture?

Back

Osteoclasts are specialized cells that break down and remove damaged bone tissue during the healing process after a fracture.

Front

At the end of which stage of bone healing does the final structure resemble the original unbroken bone?

Back

Remodeling is the final stage of bone healing where the bone is reshaped and strengthened to resemble its original structure.

Front

Bone forming cells are called...

Back

Osteoblasts are the cells responsible for bone formation, synthesizing new bone matrix and facilitating mineralization.

Front

If a fracture is comminuted, that means the bone is in _______ pieces.

Back

Multiple pieces; a comminuted fracture is one where the bone is shattered into several fragments.

Front

What is the first stage of bone healing?

Back

Hematoma formation is the initial stage of bone healing, where blood clots form at the fracture site, providing a temporary framework for healing.

Front

What is the role of osteocytes in bone tissue?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.

Front

What is a transverse fracture?

Back

A transverse fracture is a type of bone fracture that occurs straight across the bone shaft, typically caused by a direct force.

Front

What is the function of fibrocartilaginous callus in bone healing?

Back

The fibrocartilaginous callus forms during the second stage of healing, providing a temporary bridge between the broken bone ends and facilitating further healing.

Front

What is the difference between a simple and a compound fracture?

Back

A simple fracture (closed fracture) does not break the skin, while a compound fracture (open fracture) penetrates through the skin, increasing the risk of infection.
