what is avasculature necrosis of the hip and what is the treatment?

Answer 1

Avascular necrosis is a "dying" of the hip. The only treatment I'm aware of is surgery. It is a very very painful condition, and needs immediate intervention.

Best of luck

Answer 2

Avascular necrosis is a disease resulting from the temporary or permanent loss of blood supply to the bones. Without blood, the bone tissue dies, and ultimately the bone may collapse. If the process involves the bones near a joint, it often leads to collapse of the joint surface. Osteonecrosis is also known as aseptic necrosis and ischemic necrosis. It often occurs in the hip joint. Most of the time a hip replacement is requried.

Avascular necrosis is especially common in the hip joint. A variety of methods are now used to treat avascular necrosis, the most common being the total hip replacement, or THR. However, THRs have a number of downsides including long recovery times and short life spans. THRs are an effective means of treatment in the geriatric population, however doctors shy away from using them in younger patients due to the reasons above. A new, more promising treatment is metal on metal resurfacing. It is a form of a THR, however in this procedure, only the head of the femur is removed as opposed to a THR in which the entire neck is removed. Metal on metal resurfacing is still experimental in America but has been endorsed in Great Britain as an excellent alternative to a THR. Bone is always undergoing change or remodelling. The bone is broken down by osteoclasts and rebuilt by osteoblasts. Some doctors also prescribe bisphosphonates (e.g. alendronate) which reduces the rate of bone breakdown by osteoclasts, thus preventing collapse (specifically of the hip) due to AVN.

Another treatment is the Free Vascular Fibular Graft (FVFG), in which a portion of the fibula, along with its blood supply, is removed and transplanted into the femural head.

The amount of disability that results from avascular necrosis depends on what part of the bone is affected, how large an area is involved, and how effectively the bone rebuilds itself. The process of bone rebuilding takes place after an injury as well as during normal growth. Normally, bone continuously breaks down and rebuilds--old bone is reabsorbed and replaced with new bone. The process keeps the skeleton strong and helps it to maintain a balance of minerals. In the course of avascular necrosis, however, the healing process is usually ineffective and the bone tissues break down faster than the body can repair them. If left untreated, the disease progresses, the bone collapses, and the joint surface breaks down, leading to pain and arthritis

Answer 4

the term I think you may reference to is Avascular Necrosis. It is a medical term and a disease in bones and joints when without blood temporaily or permanently can cause them to collapse at the joints. This disease also is known as osteonecrosis, aseptic necrosis, and ischemic bone necrosis.

Answer 5

avascular necrosis is tissue death due to lack of blood supply, in the hip the only treatment is hip replacement surgery, and that may not work if the circulation is bad enough. But removal of the necrotic hip is essential or gangrene and death will follow.

Answer 6

Its a loss of blood supply to a bone in which the bone in that area begins to die. The hip willmore than likely needs replaced

Answer 7

In the natural state it necessitates a sit on chair condition.Yet it is a 3 part duration.The centre being independent of the left and right part.A non-attached, that does not make way for cemented rights,relationship is essential for cure.

Answer 8

avascular necrosis, also known as osteonecrosis, is a condition caused from many things such as alcoholism, excessive steroid use, post trauma, Caisson disease (decompression sickness), vascular compression, hypertension, vasculitis, thrombosis, damage from radiation and (very rarely) sickle cell anaemia. In some cases it is idiopathic (no cause is found).
