Hip Replacement — Conditions We Treat

  • Avascular necrosis (also called osteonecrosis) occurs when blood flow to bones in the joints is disrupted. Deprived of blood, the bone eventually starts to die and may eventually collapse.
  • Cancer of the bones can either travel to bone from other organs (metastatic bone cancer), or it can begin in the cells of the bone itself (primary bone cancer).
  • With osteoarthritis, or degenerative arthritis, the cartilage that cushions joints loses its elasticity and wears away in places. This makes the bones rub together, causing pain, stiffness and swelling. In addition to wear and tear, research by rheumatologists at Rush and other centers suggests that inflammation may contribute to the development of osteoarthritis.
  • Rheumatoid arthritis (RA) is an autoimmune disease that causes inflammation in joints. As it progresses, RA can cause joint deformity and even lead to disability.
