Also known as Ischemic Necrosis and Avascular Necrosis Of Bone
Avascular necrosis (also osteonecrosis, bone infarction, aseptic necrosis, ischemic bone necrosis, and AVN) is a disease where there is cellular death (necrosis) of bone components due to interruption of the blood supply. Without blood, the bone tissue dies and the bone collapses. If avascular necrosis involves the bones of a joint, it often leads to destruction of the joint articular surfaces. (see Osteochondritis dissecans).Source: Wikipedia
Within all the people who go to their doctor with avascular necrosis, 86% report having hip pain, 53% report having knee pain, and 45% report having shoulder pain. The symptoms that are highly suggestive of avascular necrosis are hip pain, bowlegged or knock-kneed, shoulder stiffness or tightness, and shoulder weakness, although you may still have avascular necrosis without those symptoms.
Patients with avascular necrosis often receive radiographic imaging procedure, plain x-ray, complete physical skin exam performed (ml), magnetic resonance imaging, physical therapy exercises, other diagnostic procedures (interview; evaluation; consultation), lipid panel and prostate specific antigen measurement .
|Radiographic imaging procedure|
|Plain x-ray (X ray)|
|Complete physical skin exam performed (ML)|
|Magnetic resonance imaging (Mri)||$297|
|Physical therapy exercises (Exercises)|
|Other diagnostic procedures (interview; evaluation; consultation)||$101|
|Prostate specific antigen measurement (Prostate specific antigen test)|
The most commonly prescribed drugs for patients with avascular necrosis include oxycodone, emtricitabine-tenofovir, ritonavir (norvir), mycophenolate mofetil (cellcept), hydroxychloroquine (plaquenil), meloxicam, cyclosporine, ropinirole, oxybutynin, bupivacaine, methadone, saquinavir and lopinavir .
|Mycophenolate Mofetil (Cellcept)||$263|
Groups of people at highest risk for avascular necrosis include sex == male age 45-59 years. On the other hand, race/ethnicity = other, age 1-4 years, and age < 1 years almost never get avascular necrosis.
