In orthopedics, it is most commonly discussed in the hip as a radiographic sign of femoral head avascular necrosis (AVN). It is used by clinicians and radiologists to help recognize structural weakening of bone near the articular surface. The term shows up mainly in X-ray interpretation, and sometimes in CT or MRI discussions for context."}
