case_images: (Case 1) Preoperative anteroposterior X-ray of pelvis with both hips showing normal hip joint and femoral necks.

case_images: The lumbar MR showed L5-S1 stenosis [Figure 1].
case_images: (Case 1) Magnetic resonance imaging showing fracture of the neck of both femurs (a) magnetic resonance imaging and (b) computed tomography.

case_images: Although X-rays of both hips were negative, the MRI and computed tomography studies both demonstrated bilateral hip fractures [Figure 2].
case_images: (Case 1) Postoperative anteroposterior X-ray of both hip joints showing cannulated cancellous screw fixation of both the femoral necks.

case_images: The patient, therefore, first underwent bilateral hip joint fixation with cannulated cancellous screws followed by endoscopic lumbar decompression at the L5-S1 level [Figure 3].

case_images: F4
case_images: X-rays and the lumbar MRI were normal. X-rays of both hips were negative, but the MRI of studies showed Ficat Stage I of AVN of both femoral heads [Figures 4 and 5].
case_images: (Case 2) Magnetic resonance imaging of both hips showing avascular necrosis of both femoral heads (a) T1 coronal and (b) T2 coronal.

case_images: X-rays and the lumbar MRI were normal. X-rays of both hips were negative, but the MRI of studies showed Ficat Stage I of AVN of both femoral heads [Figures 4 and 5].
