What is trochanteric bursitis?
Trochanteric bursitis is inflammation (swelling) of the bursa (fluid-filled sac near a joint) at the outside (lateral) point of the hip known as the greater trochanter. When this bursa becomes irritated or inflamed, it causes pain in the hip. This is a common cause of hip pain.
What causes trochanteric bursitis?
Trochanteric bursitis can result from one or more of the following events:
- Injury to the point of the hip. This can include falling onto the hip, bumping the hip into an object, or lying on one side of the body for an extended period.
- Play or work activities that cause overuse or injury to the joint areas. Such activities might include running up stairs, climbing, or standing for long periods of time.
- Incorrect posture. This condition can be caused by scoliosis, arthritis of the lumbar (lower) spine, and other spine problems.
- Stress on the soft tissues as a result of an abnormal or poorly positioned joint or bone (such as leg length differences or arthritis in a joint).
- Other diseases or conditions. These may include rheumatoid arthritis, gout, psoriasis, thyroid disease or an unusual drug reaction. In rare cases, bursitis can result from infection.
- Previous surgery around the hip or prosthetic implants in the hip.
- Hip bone spurs or calcium deposits in the tendons that attach to the trochanter.
Bursitis is more common in women and in middle-aged or elderly people. Beyond the situations mentioned above, in many cases, the cause of trochanteric bursitis is unknown.
What are the symptoms of trochanteric bursitis?
Trochanteric bursitis typically causes the following symptoms:
- Pain on the outside of the hip and thigh or in the buttock.
- Pain when lying on the affected side.
- Pain when you press in or on the outside of the hip.
- Pain that gets worse during activities such as getting up from a deep chair or getting out of a car.
- Pain with walking up stairs.
