Greenstick fracture

Verified step by step guidance

Step 1: Begin by understanding the definition of a bone fracture. A fracture is a break in the continuity of a bone, often caused by trauma or stress.

Step 2: Review the types of fractures listed in the problem. Each type has distinct characteristics: - Spiral fracture: Occurs when a twisting force is applied to the bone, causing a spiral-shaped break. - Comminuted fracture: The bone is shattered into multiple pieces. - Greenstick fracture: A partial fracture where one side of the bone bends and the other side breaks. - Impacted fracture: Occurs when the broken ends of the bone are driven into each other.

Step 3: Focus on the description provided in the problem: 'broken bone ends are forced into each other.' This matches the definition of an impacted fracture.

Step 4: Eliminate the other options based on their definitions. Spiral fractures involve twisting, comminuted fractures involve shattering, and greenstick fractures are partial breaks, none of which describe the ends of the bone being forced into each other.

Step 5: Conclude that the correct type of fracture described in the problem is an impacted fracture, as it aligns with the given description.
