<h3>What is a fracture?</h3>

A fracture is a complete or partial break in a bone. The causes of bone fractures include trauma, overuse, and diseases that weaken bones.

In this case, Kyndall was lucky because the fracture occurred about 3 inches below the epiphyseal plate as this means the fracture does not break through the bone at the growth plate.
