Which type of fracture occurs due to twisting or rotational forces on the bone?
Greenstick fracture
Transverse fracture
Spiral fracture
Comminuted fracture
The Correct Answer is C
A spiral fracture occurs due to twisting or rotational forces on the bone, resulting in a twisting break along the bone's length.
a. Greenstick fracture: A greenstick fracture involves the bone bending and partially breaking, usually seen in children. It is not caused by twisting forces.
b. Transverse fracture: A transverse fracture occurs when the bone breaks straight across its long axis, not due to twisting.
d. Comminuted fracture: In a comminuted fracture, the bone breaks into multiple pieces, which is not associated with twisting forces.

Correct Answer is A
Explanation
An open fracture, also known as a compound fracture, occurs when the bone penetrates the skin and is exposed to the external environment. It carries a higher risk of infection due to the exposure of the bone to external contaminants.
b. Closed fracture: A closed fracture, also known as a simple fracture, does not break the skin, and the bone remains enclosed within the body.
c. Impacted fracture: An impacted fracture occurs when the bone ends are forced into each other, commonly seen in long bones such as the femur. It does not involve the bone penetrating the skin.
d. Stress fracture: A stress fracture is a tiny crack in the bone caused by repetitive stress and overuse. It does not involve the bone penetrating the skin.
Correct Answer is A
Explanation
A greenstick fracture involves the bone bending and partially breaking, with one side of the bone being broken and the other side bent.
b. Transverse fracture: A transverse fracture occurs when the bone breaks straight across its long axis, not involving bending.
c. Oblique fracture: An oblique fracture involves a diagonal break, not breaking on one side and bending on the other.
d. Stress fracture: A stress fracture occurs due to repetitive stress on the bone, not involving one side breaking and the other side bending.
