Other causes of hip pain
Certain other factors can cause hip pain.
Osteonecrosis occurs when part of the bone does not get enough blood supply and dies. After a while the bone will become weak and collapse. If this condition is not treated, bone damage gets worse. Eventually, the damaged part of the bone may collapse and cause arthritis.
Osteonecrosis can be caused by disease, drinking, steroid use, or by severe trauma such as a break or dislocation, that affects the blood supply to the bone. In many cases, no trauma or disease was present.
One of the most common places for osteonecrosis to occur is in the hip joint. There are no symptoms in the early stages. As bone damage gets worse, you may have the following symptoms:
- Pain in the joint that may increase over time and will become very severe if the bone collapses
- Pain that occurs even at rest
- Limited range of motion
- Groin pain, if damage is in the hip joint
- Limping, if the condition occurs in or below the hips
Hip fractures, or a broken hip bone, are common causes of hip pain after falls. Hip fractures often occur in older people. Osteoporosis, or weakening of your bones, increases your risk for hip fractures. Stress fractures can also cause hip pain. Various risk factors increase your risk for developing a stress fracture in the hip joint.
