A dislocation happens when extreme force is put on a joint. It can occur if your child falls or takes a hit to the body, such as while playing a contact sport.
When a dislocation occurs, ligaments are torn. Ligaments are flexible bands of fibrous tissue. They join various bones and cartilage. They also bind the bones in a joint together. The hip and shoulder joints, for example, are called ball and socket joints. Lots of force on the ligaments in these joints can cause the head of the bone (ball) to partly or fully come out of the socket. The most commonly dislocated joint is the shoulder.
