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.

  • Avascular Necrosis

    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 to evaluate prevalence of radiographic hand OA in a total Russian sample, After the age of 65, 98.5% of males and 96.8% of females had at least one affected joint.

    In individuals younger than 50, OA was most prevalent in the metacarpophalangeal joints, and after age 50, was most prevalent in the distal interphalangeal joints. Prevalence of hand OA was significantly higher in males than in females in ages 35–50. After adjustment for age, age2 and place of residence, there were no associations between prevalence or severity of hand OA and BMI. According to a statistical analysis there are Extrapolated Incidence of Avascular Necrosis is 5293 in Russia.
