Causes of hip pain
Arthritis is the most common cause of disability and chronic pain of the hip. Other common causes are osteoarthritis, rheumatoid arthritis and traumatic arthritis.
Osteoarthritis: is an age related wear and tear condition, common after 50 years of age and in those with a family history of arthritis. The cartilage in the joint wears away and the bones rub against each other, causing hip pain and stiffness.
Rheumatoid arthritis: is an auto immune disorder where the body reacts against its own cells, which it recognizes as a foreign tissue. The synovial membranes become inflamed and thickened and over time the cartilage becomes degenerated, leading to pain and stiffness.
Post traumatic arthritis: follows a serious hip injury or fracture, where the cartilage becomes damaged leading to pain and stiffness.
Avascular necrosis: Any injury to the hip, such as dislocation or fracture, may limit blood supply to the femoral head, leading to death of the part of the bone and the surface of the bone collapses, causing arthritis.
Childhood hip disease: even if treated can lead to arthritis in adulthood as the bone growth is reduced
