Bursa is a buffer structure at body locations with frequent friction or heavy pressure. The outer layer is fibrous connective tissue and the inner layer is synovial capsule. There is a small amount of synovial fluid inside bursa to facilitate sliding. Bursitis is acute or chronic inflammation of a bursa. Many joint diseases can cause bursitis. Symptoms: gradual emergence of a round or oval mass in the joint or bone protrusions for no specific reasons. It grows slowly with tenderness. If applying heavy external force, the mass size increases rapidly, along with severe pain. The skin can have redness and warmth, but no edema. Treatment: For traumatic bursitis, puncture and draw the synovial fluid, and inject prednisolone acetate. For bursitis caused by skeletal deformities, the deformities should be corrected. If non-surgical therapy is ineffective, the bursa can be removed by surgery. If there is secondary infection, it should be cut open and drained.
