Avascular Necrosis

Avascular Necrosis Information for Patients


Avascular-Necrosis-InformationAvascular necrosis is a condition of the femoral head where the blood supply is affected to the head of the femur such that the bone affected gradually collapses. This can be from a variety of causes including the use of Corticosteroids, excessive alcohol intake or rare conditions such as Sickle cell disease. The cause for the majority of cases of Avascular Necrosis (AVN) are however unknown. This condition is often difficult to identify on simple X-rays in its early stages and an MRI Scan may need to be carried out to achieve a diagnosis. In late cases or where a significant portion of the femoral head has been affected hip replacement or reconstruction may need to be carried out.


Hip resurfacing has been performed on these cases with good early results. The type of operation and the results of such surgery will need to be discussed with your surgeon in detail.
