case_images: X-rays showed increased sclerosis and lyticlesions in both hips, suggestive of ONFH. X-ray was done after patient had inability to walk, which revealed increased sclerosis with decreased joint space, loss of contour with subcapital femoral neck fracture(Fig. 1).Magnetic resonance imaging (MRI) pelvis with both hips revealed osteonecrosis involving both heads and pathological subcapital fracture on the right side.(Fig. 2) Presentation of ONFH with subcapital fracture has not been included in the commonly used classifications.

case_images: Our intraoperative findings revealed that margins of the fracture were irregular with no capacity to bleed(Fig. 3).Cemented THA was done.

case_images: Gross necrosis in the marrow and lipid infiltration was reported in histopathology of the femoral head which is consistent with osteonecrosis (Fig. 4).
