What is Bursa?

Bursa is an important part of the anatomy of the joint that is designed to reduce friction so that the joint can move freely with minimal resistance. Bursae enables the joints of the body to articulate repeatedly throughout their lives, while resisting pressures, such as the impact of running or pulling on the joint that can be caused by severe lifting. In the human body there are 160 Bursae in various places, from considerable joints on the shoulder and knee to a fine and very important joints in the hands and legs.

The term "bursa" is derived from the latin for the "handbag". These structures are in the form of small bags filled with liquid. When the joint elements, including bones, cartilage and bindings, articulate in motion, instead of rubbing for themselves, winging on bursa. This distributes joint movement voltage and also reduces friction, allowing the joint to be very smoothly and evenly over the entire range of movements.

usually Bursae are very thin. To effectively insulate the joint nThe necessary power of the material. The SAC outer layer is a hard capsule that is designed to prevent rupture, and the interior is lined with a synovial membrane, a type of tissue that includes specialized cells known as fibroblasts. Fibroblasts are cells that eliminate fibrous materials and produce synovial fluid in the case of Bursae. This fluid is about the texture of egg whites, which is the ideal weight for joint lubricant. Other cells inside the structure are removed by contaminants that go to the burry to protect it from infection.

Sometimes Bursa becomes inflamed in a state called bursitis. When it is irritated, fibroblasts go to overdrive and begin to produce a high volume of synovial fluid. This causes the bag to swell. The joint becomes stiff and painful because instead of reducing friction, swollen Bursa exerts pressure on the joint. Rest can allow the swelling to drop and sometimes anti -inflammatory drugs will be prescribed to reduce the swelling. Other treatment techniques include an increase in joint and icing.

In some cases, surgery is required for the burs. This can happen when SAC is torn or grossly swollen and inflamed. Some people with arthritis develop chronic inflammation in the burnet, resulting in damage to their joints. Surgery can be used to complete the joint or to address tears. It is often performed arthroscopically, using a camera to view the inside of the joints and small cuts to introduce tools.
