How can a transverse fracture happen?

How can a comminuted fracture happen?
How can a greenstick fracture happen?
How can a spiral fracture happen?
How can a avulsion fracture happen?
Answer all five of these please!!

1. Transverse Fracture: A transverse fracture can happen when a strong force is applied perpendicular to the bone, causing it to break horizontally across the bone.

2. Comminuted Fracture: A comminuted fracture can happen when a significant amount of force is applied to the bone, causing it to break into multiple pieces.

3. Greenstick Fracture: A greenstick fracture can happen in children whose bones are not fully developed and more flexible. It occurs when the bone partially breaks, causing it to bend on one side while breaking on the other.

4. Spiral Fracture: A spiral fracture can happen when a twisting force is applied to a bone, causing it to break in a spiral pattern along the length of the bone.

5. Avulsion Fracture: An avulsion fracture can happen when a strong muscle contraction or sudden impact pulls a tendon or ligament away from the bone, causing a small fragment of bone to break off.
