Hip Bursitis
Hip bursitis facts
- A bursa is a fluid-filled sac that functions as a gliding surface to reduce friction between moving tissues of the body.
- There are two major bursae of the hip.
- Bursitis, or inflammation of a bursa, is usually not infectious, but the bursa can become infected.
- Treatment of noninfectious bursitis includes rest, ice, and medications for inflammation and pain. Infectious bursitis (uncommon) is treated with antibiotics, aspiration, and surgery.
- Bursitis of the hip is the most common cause of hip pain.
- Trochanteric bursitis frequently causes tenderness of the outer hip.
- Ischial bursitis can cause dull pain in the upper buttock area.

What is bursitis?
A bursa is a closed fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. "Bursae" is the plural form of "bursa." The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees. When a bursa becomes inflamed, the condition is known as "bursitis."

What is hip bursitis?
There are two major bursae of the hip, the trochanteric bursa and the ischial bursa. These are located adjacent to the edges of the femur (thighbone) and pelvic bone, respectively. Inflammation of either can be associated with stiffness and pain around the hip joint. The trochanteric bursa is located on the side of the hip. It is separated significantly from the actual hip joint by tissue and bone. Bursitis is not arthritis and, therefore, is not a cause of true joint pain.

What causes hip bursitis?
Most commonly, bursitis is a noninfectious condition (aseptic bursitis) caused by inflammation that results from local soft-tissue trauma or strain injury. On rare occasions, the hip bursa can become infected with bacteria. This condition is called septic bursitis. Although uncommon, the hip bursa can become inflamed by crystals that deposit there from gout or pseudogout, or from calcinosis as a result of scleroderma.
What are risk factors for hip bursitis?
Risk factors for hip bursitis include activities that could strain the hip area, including going up and down stairs, repetitive activities such as stair-climber exercising, etc.

What are hip bursitis symptoms and signs?
Bursitis of the hip is the most common cause of hip pain.
Trochanteric bursitis
Trochanteric bursitis frequently causes pain and tenderness of the outer hip and thigh, making it difficult for those affected to lie on the involved side, frequently causing difficult sleep. Trochanteric bursitis also causes a dull, burning pain on the outer hip and thigh that is often made worse with excessive walking, exercise, or stair climbing. Iliotibial band syndrome can sometimes mimic or be associated with trochanteric bursitis.
Ischial bursitis
The ischial bursa is located in the upper buttock area. Ischial bursitis can cause dull pain in this area that is most noticeable when climbing uphill. The pain sometimes occurs after prolonged sitting on hard surfaces, hence the names "weaver's bottom" and "tailor's bottom."
