The hip is a ball-and-socket joint. The “ball” is the top of the thigh bone (femur), and the “socket” is part of the pelvis. A hip dislocation occurs when the ball is forced out of the socket, causing the joint to come apart. In most cases, the ball moves up and forward out of the socket, but it can sometimes move downward instead.
This type of injury is most commonly caused by trauma, such as being hit by a car or experiencing a significant fall. However, it can happen with less obvious injury. When the hip becomes dislocated, the tissues that normally hold the joint in place are damaged. This makes the joint unstable and prevents it from working normally.
