Information for Patients


Hip Injuries and Disorders

Your hip is the joint where your thigh bone meets your pelvis bone. Hips are called ball-and-socket joints because the ball-like top of your thigh bone moves within a cup-like space in your pelvis. Your hips are very stable. When they are healthy, it takes great force to hurt them. However, playing sports, running, overuse or falling can all sometimes lead to hip injuries. These include

  • Strains
  • Bursitis
  • Dislocations
  • Fractures

Certain diseases also lead to hip injuries or problems. Osteoarthritis can cause pain and limited motion. Osteoporosis of the hip causes weak bones that break easily. Both of these are common in older people.

Treatment for hip disorders may include rest, medicines, physical therapy, or surgery, including hip replacement.

Legg-Calvé-Perthes disease Legg-Calvé-Perthes disease is a bone disorder that affects the hips. Usually, only one hip is involved, but in about 10 percent of cases, both hips are affected. Legg-Calvé-Perthes disease begins in childhood, typically between ages 4 and 8, and affects boys more frequently than girls.In this condition, the upper end of the thigh bone, known as the femoral head, breaks down. As a result, the femoral head is no longer round and does not move easily in the hip socket, which leads to hip pain, limping, and restricted leg movement. The bone eventually begins to heal itself through a normal process called bone remodeling, by which old bone is removed and new bone is created to replace it. This cycle of breakdown and healing can recur multiple times. Affected individuals are often shorter than their peers due to the bone abnormalities. Many people with Legg-Calvé-Perthes disease go on to develop a painful joint disorder called osteoarthritis in the hips at an early age.
