Bones break in a variety of ways, from hairline fractures to complete breaks. The most common types of fractures include oblique, comminuted, spiral, compound, greenstick, transverse, and simple fractures. Compound fractures are open fractures where the bone pierces the skin, posing a risk of infection. Greenstick fractures occur more often in children due to their flexible bones. Proper nutrition including calcium, vitamin D, and other vitamins supports healing of broken bones.
