Progressive Hip Arthritis With AVN
Avascular necrosis (AVN) is also known by many other names. These include osteonecrosis, ischemic necrosis, aseptic necrosis and bone infarction. Essentially, AVN is a condition in which the blood supply to the bone is disrupted leading to bone cell death (necrosis).
The hip is the most frequent joint involved and AVN can affect one or both hips. The most frequent cause of AVN is trauma from sports, a car accident or some other incident. Other causes include idiopathic (unknown causes) and those with risk factors due to other causes such as high corticosteroid (cortisone) use or systemic disorders.
When a section of bone becomes necrotic, this area may erode or collapse. This can lead to a rapidly progressive secondary arthritis. If the area of AVN can be treated successfully no progression of degeneration occurs. With prevention of secondary degeneration, the hip joint may remain stable and hip joint replacement can be avoided. If progression develops quickly the loss of joint surface may ensue require hip replacement. Early diagnosis is important to prevent the effects of progressive hip arthritis.
