Which fracture type is commonly seen in osteoporotic bones, especially in older adults?
Compression fracture
Avulsion fracture
Greenstick fracture
Impacted fracture
The Correct Answer is A
A compression fracture is commonly seen in osteoporotic bones, especially in older adults, due to decreased bone density and strength. It occurs when the bone is compressed and collapses, often resulting from a fall or minor trauma.
b. Avulsion fracture: An avulsion fracture occurs when a small piece of bone is torn away from the main bone due to the pull of a ligament or tendon. It can happen in individuals of all ages.
c. 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.
d. Impacted fracture: An impacted fracture occurs when the broken ends of the bone are driven into each other, often seen in long bones like the femur or humerus. It can occur in individuals of all ages.

Explanation
X-ray (radiography) is the most common imaging modality used to diagnose fractures in the emergency department. X-rays can visualize the bone's structure and detect fractures, bone displacement, or other abnormalities.
a. Magnetic Resonance Imaging (MRI): MRI is useful for soft tissue evaluation but is not routinely used for initial fracture diagnosis in the emergency department.
b. Computed Tomography (CT): CT scans provide detailed cross-sectional images of bones and soft tissues, but they are not typically the first-line imaging for initial fracture assessment in the emergency department.
d. Ultrasound: Ultrasound is useful for certain soft tissue evaluations but is not commonly used for diagnosing fractures.
Correct Answer is C
Explanation
: Stress fractures are small, hairline cracks in the bone that occur due to repetitive stress or overuse. They typically present with a gradual onset of localized pain that worsens with activity.
a. Severe pain and deformity: Severe pain and deformity are more commonly seen in acute fractures resulting from trauma or high-impact injuries, not stress fractures.
b. Sudden onset of swelling and bruising: Sudden onset of swelling and bruising is more indicative of acute fractures, not stress fractures.
d. Inability to bear weight on the affected limb: Inability to bear weight may be present in some fractures, but it is not a specific characteristic of stress fractures.
