What is a joint?

A joint is where two or more bones meet.

Bones are much too rigid to bend. In order that we can move, our skeleton is held together by a number of different types of joints. All movements that change the position of our skeleton take place at joints.

Special case

Although bones are much too rigid to bend, children may experience what is called a ‘greenstick’ fracture where one side breaks but the other side bends. The injury occurs because the young skeleton is still growing. It is called a ‘greenstick’ fracture as it behaves exactly like a young branch of a tree. This type of fracture is rare in adults due to the brittleness of the bone.
