case_images: fig1
case_images: Pelvic radiographs (AP and frog lateral in Figures 1 and 2) were reviewed and showed avascular changes to the femoral head with the characteristic "crescent sign" of osteonecrosis, a subchondral lucency, in the femoral epiphysis.
case_images: Frog leg lateral X-ray of bilateral hips again showing avascular changes with characteristic "crescent sign" of osteonecrosis to right femoral head.

case_images: Pelvic radiographs (AP and frog lateral in Figures 1 and 2) were reviewed and showed avascular changes to the femoral head with the characteristic "crescent sign" of osteonecrosis, a subchondral lucency, in the femoral epiphysis.
case_images: AP pelvis X-ray obtained 6 weeks from initial presentation which shows early femoral head collapse.

case_images: These repeat images (Figures 3 and 4) show the continued progression of the pathology, with sequential flattening of the femoral head as is expected in osteonecrosis.
case_images: AP pelvis X-ray obtained 12 weeks from initial presentation with progressive flattening of femoral epiphysis indicative of segmental collapse seen in non-Perthes osteonecrosis.
