Bursitis is caused by inflammation of a bursa, a small jelly-like sac that usually contains a small amount of fluid. Bursae are located throughout the body, most importantly around the shoulder, elbow, hip, knee, and heel. They act as cushions between bones and the overlying soft tissues, and help reduce friction between the gliding muscles and the bone.
Another bursa located on the inside (groin side) of the hip is called the iliopsoas bursa. When this bursa becomes inflamed, the condition is also sometimes referred to as hip bursitis, but the pain is located in the groin area. This condition is not as common as trochanteric bursitis, but is treated in a similar manner.
The main symptom of hip bursitis is pain at the point of the hip. The pain usually extends to the outside of the thigh area. In the early stages, the pain is usually described as sharp and intense. Later, it may feel more achy and spread out.
Typically, the pain is worse at night, when lying on the affected hip, and when getting up from a chair after being seated for a while. It also may get worse with prolonged walking, stair climbing, or squatting.
Hip bursitis can affect anyone, but is more common in women and middle-aged or elderly people. It is less common in younger people and in men.
The following risk factors have been associated with the development of hip bursitis.
- Repetitive stress (overuse) injury. This can occur when running, stair climbing, bicycling, or standing for long periods of time.
- Hip injury. An injury to the point of your hip can occur when you fall onto your hip, bump your hip on the edge of a table, or lie on one side of your body for an extended period of time.
- Spine disease. This includes scoliosis, arthritis of the lumbar (lower) spine, and other spine problems.
- Leg-length inequality. When one leg is shorter than the other by more than an inch or so, it affects the way you walk and can lead to irritation of a hip bursa.
- Rheumatoid arthritis. This makes the bursae more likely to become inflamed.
- Previous surgery. Surgery around the hip or prosthetic implants in the hip can irritate bursae and cause bursitis.
- Bone spurs or calcium deposits. These can develop within the tendons that attach to the trochanter. They can irritate the bursa and cause inflammation.
The initial treatment for hip bursitis does not involve surgery. Many people with hip bursitis can experience relief with simple lifestyle changes, including:
- Modification of activities—avoiding the activities that worsen symptoms
- Use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, naproxen, piroxicam, celecoxib, and others, to control inflammation and pain
- Use of a walking cane or crutches for a week or more when needed
There is little evidence to support the use of physical therapy to treat hip bursitis, but many patients claim that it is helpful. The doctor may ask a physical therapist to teach you how to stretch your hip muscles and use other treatments such as ice, heat, or ultrasound.
Injection of a corticosteroid along with a local anesthetic may also be helpful in relieving symptoms of hip bursitis. This is a simple and effective treatment that can be done in the doctor's office. It involves a single injection into the bursa. The injection typically provides permanent relief. If pain and inflammation return, another injection or two, given a few months apart, may be needed.
Use NSAIDs cautiously and for limited periods. Talk with your doctor about the NSAIDs you use. NSAIDs may have adverse side effects if you have certain medical conditions or take certain medications.
Surgery is rarely needed for hip bursitis. If the bursa remains inflamed and painful after all nonsurgical treatments have been tried, your doctor may recommend surgical removal of the bursa. Removal of the bursa does not hurt the hip, and the hip can actually function normally without it.
A newer technique that is gaining popularity is arthroscopic removal of the bursa. In this technique, the bursa is removed through a small (1/4-inch) incision over the hip. A tiny camera, or arthroscope, is placed in a second incision so the doctor can guide the surgical instruments and cut out the bursa. This surgery is much less invasive, and recovery is quicker and less painful.
Both types of surgeries are done on an outpatient (day surgery) basis, so an overnight stay in the hospital is not usually necessary. Early studies show arthroscopic removal of the bursa to be quite effective, but this is still currently being studied.
Following surgery, a short rehabilitation period can be expected. Most patients find that using a cane or crutches for a couple of days is helpful. It is reasonable to be up and walking around the evening after surgery. The soreness from surgery usually goes away after a few days.
Prevention is aimed at avoiding behaviors and activities that make the inflammation of the bursa worse.
- Avoid repetitive activities that put stress on the hips.
- Lose weight if you need to.
- Get a properly fitting shoe insert for leg-length differences.
- Maintain strength and flexibility of the hip muscles.
