Occasionally, the cavity of a bursa communicates with the cavity of a synovial joint. For example, the suprapatellar bursa communicates with the knee joint, and the subscaularis bursa communicates with the shoulder joint.
Disorders of bursaeInflammation of a bursa is called bursitis and can be extremely painful. A bursitis may be visible as a red and tender swelling on the surface, as at the elbow, or it may be hidden in deeper layers such as within the buttock, groin, or hip. Treatment involves reducing the swelling and prevention of further inflammation.
A bunion is a thickened bursa at the base of the big toe.
