Question

little jimmy is a toddler. his mother brought him in with an injured arm. an x - ray confirms jimmy has a fractured humerous that appears to have been twisted apart. this type of fracture is highly suspicious for abuse since it is typically the result of forceful twisting or jerking of an extremity, especially in a child of this age. the nurse immediately calls child protective services.
a greenstick
b colles
c spiral
d stress

Explanation:

• A greenstick fracture is an incomplete fracture where the bone bends and cracks, not twisted apart.
• A Colles' fracture is a fracture of the distal radius (wrist area), not related to twisting.
• A spiral fracture is caused by a twisting force, which matches the description of the fracture being twisted apart.
• A stress fracture is due to repetitive stress, not a one - time forceful twisting.

Answer:

C. spiral
