The hip joint is composed of two bones and the muscles, tendons and ligaments that connect them. The two bones are the femur and pelvis. The upper end, or head, of the femur is shaped like a ball. It fits inside the acetabulum, the portion of the pelvic bone that forms the hip socket. The hip, like the shoulder, is referred to as a ball and socket joint. In contrast to the shoulder, however, the hip socket is much deeper. Because the ball is set so far down into the socket, the hip is more stable than the shoulder, and less prone to dislocation. This increase in stability comes with a sacrifice in motion. Because the socket is deep, and the walls of the socket surround the femur, the femur will contact the walls during motion, limiting how far the hip joint is able to move.

Mechanism of Injury

The hip can be injured as a result of trauma, repetitive use, or degeneration that occurs with age. Trauma is a leading cause of injury in the young. Falls onto the outside of the hip, or falls that lead to a sudden twisting injury to the hip can lead to fractures or dislocations. Repetitive use is a common cause of hip injury. Runners and cyclist develop pain around the hip. Athletes who play sports that place stress across the hip, such as soccer, hockey, and track and field, can develop hip pain. Finally, normal wear and tear on the joint can accumulate over a lifetime, and lead to arthritis or tears of the tendons and ligaments without any specific injury.
