Why does a child's fracture heal more rapidly than the adults?
A child's bones are less porous than adult bone.
A child's bones are not affected by bone overgrowth.
A child's bones are covered by a thicker periosteum.
A child's bones have slower callus formation.
The Correct Answer is C
A. Children’s bones are actually more porous, not less, which contributes to their flexibility but not faster healing.
B. Bone overgrowth is a normal response in children and is not a limiting factor in healing.
C. Children’s bones have a thicker, more active periosteum, which is the outer membrane of bone involved in healing and bone formation. This enhanced periosteal activity helps in faster callus formation and bone repair.
D. Children have faster, not slower, callus formation, contributing to their quicker healing times.

Correct Answer is B
Explanation
A. Circulatory congestion of the skin does not directly cause the intense, deep pain associated with osteomyelitis.
B. Osteomyelitis is an infection of the bone, often involving the bone marrow. The buildup of purulent material increases pressure within the rigid bone structure, causing severe pain.
C. While casts can cause discomfort if improperly applied, the primary source of pain in osteomyelitis is the infection itself.
D. Inelastic bone structure may contribute to pressure buildup, but this is secondary to the infection in the bone marrow, which is the direct cause of pain.
Correct Answer is B
Explanation
A. A fracture that has not broken through the skin is called a closed or simple fracture, not a greenstick fracture.
B. A greenstick fracture occurs when the bone bends and cracks but does not break completely, commonly seen in children due to their softer bones.
C. A bone broken into two distinct pieces is a complete fracture.
D. Bone shattered into more than two pieces is called a comminuted fracture.
