Avascular necrosis of femoral head

Case contributed by Dr Ivan Turkalj

Presentation

Left hip pain in a patient suffering from aplastic anemia treated with corticosteroids.

Patient Data

Age: 35
Gender: Male
Modality: X-ray

There is ill-defined mixed sclerotic and lytic lesion of the left femoral head. Additional cortical collapse of the superior aspect of the femoral head is noted with a linear area of lucency below it (crescent sign), measuring around 20mm. No evidence of secondary degenerative changes.

Case Discussion

Patient history and radiographical findings correlate with Ficat stage III avascular necrosis of the hip.

Avascular necrosis of the hip is more common than other sites, presumably due to a combination of precarious blood supply and high loading when standing.
