FIGURE 2.23. A 28-year-old man with recent onset of right hip symptoms, but no restriction in activities. (A) An AP radiograph reveals evidence of stage IV AVN characterized by joint space preservation and no apparent acetabular involvement. (B) An MRI scan further defines the extent of femoral head involvement. (C) View ing from the posterolateral portal, the entire articular surface is de-laminated off the medial aspect of the femoral head (asterisk). The lateral extent is marked with the probe. (D) The position of the probe is evident on the fluoroscopic image and corresponds with the lateral margin of the lesion evident on the radiograph.
