Which fracture type involves a break in the bone that is at an angle to the long axis of the bone?
Oblique fracture
Spiral fracture
Transverse fracture
Greenstick fracture
The Correct Answer is A
An oblique fracture involves a break in the bone that is at an angle to the long axis of the bone. It is often the result of a diagonal force applied to the bone.
b. Spiral fracture: A spiral fracture occurs when the bone is twisted, causing a spiral-shaped fracture line. It often results from a twisting force applied to the bone and is not specifically at an angle to the long axis of the bone.
c. Transverse fracture: A transverse fracture is a type of fracture where the fracture line is perpendicular to the long axis of the bone and is not at an angle.
d. Greenstick fracture: A greenstick fracture is an incomplete fracture seen in children, where the bone bends and partially breaks on one side but remains intact on the other side. It is not specifically at an angle to the long axis of the bone.

Correct Answer is A
Explanation
A greenstick fracture is an incomplete fracture where the bone breaks incompletely, with one side bending and the other side breaking. It is commonly seen in children due to their more flexible bones.
b. Comminuted fracture: A comminuted fracture occurs when the bone is crushed and shattered into multiple fragments, but it does not involve one side bending and the other side breaking.
c. Spiral fracture: A spiral fracture occurs when the bone is twisted, resulting in a spiral-shaped fracture line. It does not involve one side bending and the other side breaking.
d. Oblique fracture: An oblique fracture occurs when the bone breaks at an angle, but it does not involve one side bending and the other side breaking.
Correct Answer is D
Explanation
Hypertrophic nonunion occurs when there is excessive callus formation at the fracture site, but the bone ends fail to unite. This can lead to persistent pain and limited function.
a. Nonunion: Nonunion occurs when the fractured bone fails to heal and fuse together, but it does not involve excessive callus formation.
b. Malunion: Malunion refers to a fracture that heals in an incorrect position or alignment, and it is not directly related to excessive callus formation.
c. Delayed union: Delayed union refers to a fracture that takes longer than usual to heal, and it is not specifically characterized by excessive callus formation.
