Avascular Necrosis

  • Avascular Necrosis

    Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, avascular necrosis can lead to tiny breaks in the bone and the bone's eventual collapse. The blood flow to a section of bone can be interrupted if the bone is fractured or the joint becomes dislocated. Avascular necrosis typically causes no symptoms; however, as the disease progresses it becomes painful.

  • Avascular Necrosis

    At first, you may experience pain when you put pressure on the affected bone. Then, pain may become more constant. If the disease progresses and the bone and surrounding joint collapse, you may experience severe pain that interferes with your ability to use your joint. The time between the first symptoms and collapse of the bone may range from several months to more than a year. If avascular necrosis is caught early, treatment may involve taking medications to relieve pain or limiting the use of the affected area.

    If your hip, knee, or ankle is affected, crutches may be necessary to take weight off the damaged joint. Your doctor may also recommend range of motion exercises to help keep the affected joint mobile. It is also associated with Osteoarthritis and Knee injuries. According to a study in spain, Of 11 002 individuals contacted, 7577 completed the KHOA-SQ. The derived prevalence of hip osteoarthritis was approximately 7.4%. It was slightly higher in women (8.0%) than in men (6.7%) and tended to increase with age.

    The estimated appropriateness rate for hip replacement was 37.7% in men and 52.7% in women with osteoarthritis. The derived prevalence of knee osteoarthritis was 12.2%; it was significantly higher in women (14.9%) than in men (8.7%) and tended to increase with age. The estimated appropriateness rate for knee replacement was 11.8% in men and 17.9% in women with osteoarthritis. According to a statistical analysis there are Extrapolated Incidence of Avascular Necrosis is 1480 in Spain.
