Bone Fracture Flashcard

Front

What type of fracture resembles a young green twig that bends and breaks?

Back

Greenstick fracture is a type of fracture that occurs in children, where the bone bends and partially breaks, resembling a green twig.

Front

What type of fracture occurs when the body twists while the limb is stationary, often seen in skiing accidents?

Back

Spiral fracture is common in sports injuries where the bone is twisted, causing a spiral-shaped break.

Front

Which cells are responsible for producing collagen during the formation of a soft callus in bone healing?

Back

Chondroblasts are the cells that produce collagen and are involved in the formation of the soft callus during bone healing.

Front

What is the name of the cavity in long bones that contains yellow bone marrow?

Back

The medullary canal is the central cavity of long bones that contains yellow bone marrow, which is primarily made up of fat cells.

Front

Which cells are responsible for creating new bone during the formation of a hard callus?

Back

Osteoblasts are the cells that create new bone tissue during the healing process, particularly when the hard callus forms.

Front

What is a transverse fracture?

Back

A transverse fracture is a type of bone fracture that occurs straight across the bone, typically due to a direct force.

Front

Define an oblique fracture.

Back

An oblique fracture is a type of fracture that occurs at an angle across the bone, often resulting from a slanted force.

Front

What is the role of osteoclasts in bone health?

Back

Osteoclasts are cells that break down bone tissue, playing a crucial role in bone remodeling and calcium homeostasis.

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue that envelops the bones except at the surfaces of the joints.

Front

Explain the term 'Salter-Harris fracture'.

Back

A Salter-Harris fracture is a classification of fractures that involve the growth plate in children, affecting bone growth.
