ome of the most common reasons patients require shoulder replacement include:
Osteoarthritis: This age-related disease gradually wears down the cartilage around joints, allowing bones to rub against each other. The resulting friction can produce inflammation and significant pain.
Rheumatoid arthritis: This is an autoimmune disease in which the immune system inflames the lining of the joints. The swelling becomes painful and can erode the bone.
Osteonecrosis: When the flow of blood is obstructed from reaching a portion of bone, the bone tissue can break down and die, causing large joints like the shoulder or hip to collapse.
Traumatic injury: Patients who suffer a serious injury (such as a sports injury or car accident) may develop arthritis that affects the joint.
Shoulder replacement revision: If a prior shoulder replacement surgery is misaligned, has healed improperly, or develops complications, it may be necessary to repeat the procedure for better results.
