M71.4: Calcium deposit in bursa

Calcium deposit in bursa, also known as calcific bursitis, is a condition in which calcium accumulates in the bursa, a small, fluid-filled sac that cushions and protects your joints. This can occur in any bursa in the body but is most common in the shoulder, hip, elbow, and knee. The cause of these deposits is not entirely clear, but it's thought to be related to wear and tear or injury to the joint. Over time, calcium, a mineral normally found in bones, forms hard deposits in the bursa. This can cause a range of symptoms including pain that intensifies with movement or pressure, stiffness, and swelling in the affected area. If the deposits become large enough, they may limit joint mobility. The disease progression can vary with some people experiencing symptom flare-ups while others have persistent issues. It's important to note that symptoms may not always directly correspond to the size or location of the calcium deposits. It's primarily a musculoskeletal condition affecting the joints and surrounding tissues.
