A bursa, similar to an intervertebral disc, acts as a cushion/shock absorber between bony projections (joints) and nearby tendons and muscles. Bursae reduce friction between gliding muscles and the bone. Bursitis is a painful condition that affects small fluid-filled pads called bursae. Inflammation of the bursa, or bursitis can be acute or chronic. Bursitis often occurs near joints that perform frequent repetitive motion, most commonly in the shoulders, hips, elbows and knees.
At Virginia spine Institute we treat all types of bursitis but the one most commonly seen and diagnosed is hip bursitis. The bony point of the hip is on the femur, and is called the greater trochanter. It is a large attachment site for muscles that move the hip joint. The greater trochanter has a large bursa overlying it that if irritated can cause hip bursitis.
Chronic bursitis can be caused by overuse or trauma. Repetitive motion, such as throwing a baseball, repetitive kneeling, or running can lead to chronic bursitis. Chronic bursitis usually develops in patients with underlying conditions such as gout, osteoarthritis and rheumatoid arthritis. Oftentimes the cause cannot be determined.
Hip bursitis can affect anyone, but is more common in middle-aged or elderly women. It is less common in the younger population and men. However, acute or traumatic bursitis is more common in the younger population and typically is due to a sports-related injury. Repetitive motion of the hip, such a running, climbing stairs, bicycling or prolonged standing also may increase the rate of bursitis.
Most patients diagnosed with bursitis will describe a sense of pain/tenderness over the specific joint, especially when pressure is applied. Stiffness, aching, swelling and reduced range of motion can also occur over the area with bursitis. Specific to the hip, bursitis presents as pain over the hip and it usually extends to the outside thigh. Pain may be felt as sharp and intense or achy and diffuse. Symptoms are often worse at night, especially when lying on the affected side. It is also worse with hip movement, such as getting up from a chair after being seated, prolonged walking, squatting or stair climbing.
During your initial consultation, a detailed medical history will be obtained. Following that, a comprehensive physical exam will be conducted to identify areas that are tender or painful. The physical exam portion is usually the best way to diagnose bursitis. However, x-rays of the painful areas, ultrasounds, an MRI or CT may be ordered. Sometimes, if a joint or bursa is aspirated due to the inflammation, the fluid collected may be sent off to be tested in a lab to identify the cause of inflammation.
Treatment options vary for bursitis. Many people with bursitis improve with simple lifestyle changes. Temporary rest of the affected joint and avoidance of activities that worsen symptoms aid in recovery. Ice applied over the affected area as well as non-steroidal anti-inflammatory medications (NSAIDs) such as naproxen or ibuprofen help to reduce pain and inflammation. High level physical therapy is also very important in the treatment of bursitis. If the pain and inflammation does not respond to these conservative options often a bursa injection is considered.
The bursa is injected with a combination of corticosteroid along with local anesthetic to relieve symptoms of bursitis. Corticosteroids are an anti-inflammatory medication that reduces inflammation in the area injected. This is a simple and effective treatment that can be done in the office. Injections often provide long-lasting relief but if symptoms return a repeat injection may be warranted.
