Hip bursitis is a painful condition caused by inflammation of a bursa in the hip. Bursae are fluid-filled sacs that reduce friction in the joint and act as cushions during movement.
The two main hip bursae are called the trochanteric bursa (on the outside of the hip) and the iliopsoas bursa (in the groin region). Trochanteric bursitis is more common than iliopsoas bursitis.
Hip bursitis is typically caused by overusing the joint, injuring the hip, poor posture when sitting or standing, bone spurs, calcium deposits, or stress on the soft tissues. Trochanteric bursitis is common in older individuals and in athletes who are involved in running sports, such as soccer and football, that cause inflammation of the bursa.
Individuals with trochanteric bursitis often experience pain on the outside of the hip that increases with stair climbing or prolonged walking. People who have iliopsoas bursitis experience pain in the groin region.
To determine the cause of your hip pain, a hip specialist will examine the hip for swelling and tenderness. An X-ray may be recommended if bone spurs are suspected to be causing the bursa inflammation. If the reason for the pain is unclear, an MRI may be required to view the soft tissues and structures in the hip.
Conservative treatments for hip bursitis include resting and minimizing the activities that cause pain. An injection of corticosteroids may relieve inflammation and pain, and physical therapy may help to stretch and strengthen muscles and tendons. If the bursitis is severe, your physician may recommend surgery to remove the inflamed bursa.
