Hydroxyapatite deposition disease, also known as HADD, is a condition where calcium deposits form in tendons, ligaments, and other soft tissues of the body. These deposits can cause pain, stiffness, and swelling in the affected joints, including the hips. HADD can occur in people of all ages, but it is more common in individuals over the age of 60.
The hip joint is particularly vulnerable to HADD due to its weight-bearing nature and constant use. When the calcium deposits accumulate in the hip joint, it can cause a condition called calcific bursitis. This condition is characterized by inflammation of the bursae, the small fluid-filled sacs that cushion the hip joint. Calcific bursitis can cause pain and stiffness in the hip joint, making it difficult to move the leg and perform daily activities.
The exact cause of HADD is unknown, but it is believed to be related to aging and wear and tear on the body. However, certain medical conditions, such as hyperparathyroidism, can increase the risk of developing HADD. In addition, individuals who engage in repetitive activities or sports that put stress on the hip joint may also be more susceptible to this condition.
The symptoms of HADD in the hip joint can vary from person to person. Some individuals may experience mild discomfort, while others may experience severe pain and limited mobility. Common symptoms of HADD in the hip joint include:
Treatment for HADD in the hip joint typically involves managing the symptoms and reducing inflammation. This may include:
