abstract

  • A 30 degree cephalad anteroposterior tilt view of the femoral head was used, in addition to standard radiographic projections, in 55 patients having, or suspected of having, avascular necrosis of the femoral head. This method was then compared with standard views. Five patients with questionable findings on standard projections showed definite avascular necrosis, and 10 thought on standard views to have grade 2 disease were found to be grade 3, all from use of the additional projection. This projection should form part of the evaluation of suspected avascular necrosis of the femoral head.
