Avascular necrosis (AVN) most commonly affects the hip joint. It accounts for between 5 and 12% of total hip arthroplasties. This equates to approximately 15,000 new cases in the US each year. The aetiology and pathogenesis are still unclear but a number of risk factors have been identified. These include trauma (intra capsular neck of femur), smoking, corticosteroids, alcohol abuse, haemaglobinopathy, autoimmune disease, Gauchers disease and Caisson disease. Corticosteroids and alcohol account for up to 90% of non traumatic cases.

Several joint preserving techniques have been described. There is little evidence to prove that any single technique has a clear advantage. Core decompression is the most simple and associated with the least morbidity.

The results of all joint preservation techniques for AVN are better for small lesions and early stage disease.

Surgical Steps

Welcome to the surgical steps quiz.

This tests your ability to recall the correct order in which the key steps of an operation should be performed.

There will be various legitimate variations in this order but the quiz doesn’t reflect this.
Your reference point for the steps quiz is just our operative technique.
It’s one starting point in helping you to learn the technique.

  • You simply “drag & drop” the boxes containing the descriptions of the steps into the order you think fits and submit for marking.
  • If you get it correct first time you will be presented your certificate at the end of the quiz.
  • If you need to do more work on the steps you access your marked version by clicking the“re-sit the quiz” button.
  • This will show the steps you ordered correctly highlighted in green and the incorrect ones in red.
  • The correct green steps are fixed and won’t move.
  • The red steps move differently after your initial attempt and swap locations with the step they are dragged and dropped onto .
  • Finally resubmit the quiz once again.
  • The quiz will let you keep going until you get all the steps in the right order.
