Hip bursitis is a painful condition caused by inflammation of a bursa in the hip. Bursae are fluid filled sacs present in joints between bone and soft tissue to reduce friction and provide cushioning during movement.
The bony prominence of the hip is called greater trochanter and is present on the outer side of the upper thigh bone or femur. The bursa overlying it is called trochanteric bursa. Another bursa is located towards the groin region and is called iliopsoas bursa. Bursitis of the trochanteric bursa is more common than that of iliopsoas bursa.
Trochanteric bursitis is often seen in people involved in sports such as football and soccer which involve a lot of running. This can lead to overuse and irritation of the bursa causing inflammation. Bursitis may sometimes result from an injury or fall to the hip or after a surgical procedure of the hip. Spine disease, rheumatoid arthritis and leg length inequality increases the risk for developing hip bursitis.
Trochanteric bursitis results in pain on the outer side of the hip which usually increases with prolonged walking or climbing stairs. The pain is felt more while getting up from a chair and in the night when lying on the affected side. Inflammation of the iliopsoas bursa however results in pain in the groin region.
Tenderness and swelling in the area of pain over the bursa during the physical examination of the hip confirms the diagnosis of Hip Bursitis. To check for any bone spurs that could be causing irritation of the bursa your doctor may order an X-ray. If the reason for the pain is not very clear the doctor may order an MRI to view the soft tissues and structures not visible on X-ray.
