Which complication of fractures is a severe condition that results from increased pressure within a closed space?

In a greenstick fracture, the bone bends and partially breaks, usually occurring in children due to the flexibility of their bones.

a. Transverse fracture: A transverse fracture occurs when the bone breaks straight across its long axis, not bending.
b. Oblique fracture: An oblique fracture involves a diagonal break, not bending and partial breaking.
d. Avulsion fracture: An avulsion fracture occurs when a piece of bone is torn away by a ligament or tendon, not bending and partial breaking.

: 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.
