What is the most appropriate initial diagnostic study for suspected fractures?
X-ray
MRI
CT scan
Ultrasound
The Correct Answer is A
X-ray is the most appropriate initial diagnostic study for suspected fractures. It provides clear images of bones and can help identify the presence, location, and extent of the fracture.
b. MRI: MRI is useful for soft tissue imaging, but it may not be the first choice for initial evaluation of fractures. X-rays are more commonly used for immediate assessment.
c. CT scan: CT scan can provide detailed images of bones and soft tissues, but it is not typically the first-line imaging study for fractures. X-rays are more commonly performed first.
d. Ultrasound: Ultrasound is primarily used for imaging soft tissues and may not provide sufficient detail for evaluating fractures. X-rays are more appropriate for initial assessment.

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.
Correct Answer is D
Explanation
Severe pain, pallor (pale skin color), and loss of pulses distal to the fracture are concerning signs of compartment syndrome, a serious complication that requires immediate medical intervention.
a. Bruising and discoloration at the fracture site: Bruising and discoloration are common signs of inflammation and injury at the fracture site but are not specific to compartment syndrome.
b. Mild pain and swelling in the affected limb: Mild pain and swelling are expected with a fracture but do not raise immediate concerns for compartment syndrome.
c. Prolonged capillary refill distal to the fracture: Prolonged capillary refill time may indicate reduced blood flow but is not as concerning as the combination of severe pain, pallor, and loss of pulses seen in compartment syndrome.
