Trochanteric bursitis is inflammation 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.
The superficial trochanteric bursa is located over the greater trochanter. This is the most commonly inflamed bursa. A deep trochanteric bursa lies deeper and can become inflamed in more severe cases.
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.
Because most cases of bursitis are caused by overuse, the best treatment is prevention. It is important to avoid or modify the activities that cause the problem. Underlying conditions such as leg length differences, improper posture, or poor technique in sports or work must be corrected.
