Which complication of fractures is associated with persistent pain and limited function despite appropriate treatment?
Nonunion
Malunion
Delayed union
Osteomyelitis
The Correct Answer is A
Nonunion occurs when the fractured bone fails to heal and fuse together despite appropriate treatment. It is associated with persistent pain and limited function.
b. Malunion: Malunion refers to a fracture that heals in an incorrect position or alignment, but it may or may not cause persistent pain and limited function.
c. Delayed union: Delayed union refers to a fracture that takes longer than usual to heal but eventually heals properly. It is not specifically associated with persistent pain and limited function.
d. Osteomyelitis: Osteomyelitis is a bone infection that can develop as a complication of fractures, but it may or may not cause persistent pain and limited function, depending on its severity and treatment response.

Correct Answer is C
Explanation
In a closed fracture, where the skin remains intact over the fractured bone, intense localized pain and tenderness at the fracture site are common symptoms. The skin acts as a barrier, preventing bone fragments from protruding through the skin.
a. Bone fragments protruding through the skin: This symptom is associated with an open or compound fracture, where the bone pierces through the skin.
b. Visible deformity at the fracture site: Visible deformity may occur in both closed and open fractures, but it is not specific to closed fractures.
d. Open wound with bleeding at the fracture site: An open wound with bleeding is characteristic of an open or compound fracture, not a closed fracture.
Correct Answer is B
Explanation
A greenstick fracture is an incomplete fracture that commonly occurs in children due to their bones being more pliable and flexible than adult bones. In a greenstick fracture, one side of the bone bends and partially breaks, while the other side remains intact.
a. 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 can occur in both children and adults.
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 can occur in both children and adults.
d. Oblique fracture: An oblique fracture is a type of fracture where the fracture line is diagonal to the long axis of the bone and can occur in both children and adults.
