Bursae are small fluid-filled sacs that act as cushions between bones and tendons in the body. These sacs are located in areas where friction between tissues occurs, helping to reduce rubbing and pressure on the bones, muscles, and tendons. There are approximately 160 bursae in the human body, with each serving a specific function in reducing friction and pressure.
Synovial fluid, which is produced by the membranes lining the bursae, helps to lubricate the joints and reduce friction between bones and soft tissue. This fluid also contains cells that help to fight infection and keep the bursae healthy. When a bursa becomes inflamed or irritated, a condition known as bursitis can develop, causing pain, swelling, and limited range of motion in the affected joint.
Common locations of bursae
Some of the most common locations of bursae in the body include the shoulders, elbows, knees, and hips. In the shoulder, the subacromial bursa helps to reduce friction between the rotator cuff tendons and the acromion bone. In the knees, the prepatellar bursa and the infrapatellar bursa act as cushions between the patella and the skin, as well as between the patellar tendon and the tibia, respectively.
Causes of bursitis
Bursitis can be caused by repetitive movements, overuse of a joint, injury, or underlying medical conditions such as arthritis. People who engage in activities that put repetitive stress on specific joints, such as athletes, dancers, or gardeners, are at a higher risk of developing bursitis. Treatment for bursitis usually involves rest, ice, anti-inflammatory medications, physical therapy, or in severe cases, aspiration of the bursa fluid or surgical removal of the bursa.
Overall, bursae play a crucial role in maintaining joint health and function by reducing friction and pressure within the body. Taking care to avoid overuse or injury to the bursae can help prevent conditions like bursitis and ensure optimal joint function and mobility.
