An avulsion fracture occurs when fragments of bone are pulled away from their original position. It can occur due to a violent contraction of the muscle that causes a portion of bone attached to the muscle to detach. This fracture is common in the knee and shoulder joints. An impacted fracture is a condition in which one of the broken fragments of bone becomes wedged into another bone; this fracture usually occurs in an area of ​​spongy bone. A fissure fracture is the breaking of the bone that occurs parallel to the long axis of the bone and finally we have the greenstick fracture, it is a fracture in which the bones bend and break. It mostly occurs in children because their bones are softer and more flexible. (Schultz,
