Abstract
The rationale behind flexion osteotomy for idiopathic avascular necrosis of the femoral head is to place the dead part of the head away from the load [1, 2] to avoid further deformation, thus reducing pain and avoiding or at least delaying the need for a total hip arthroplasty (THA). Schneider radiological projections are mandatory to evaluate the location and the extension of the necrotic area [1]. In most cases the necrotic bone is located in the anterosuperior part of the head. The head is therefore rotated anteriorly so that almost all the necrotic area is no longer in contact with the acetabulum.
