Frog-leg view of both hips. Asymmetry with loss of the normal appearance of the left proximal femora. There is coxa magna (metaphyseal widening) and loss of the femoral epiphysis with sclerosis, lucency and fragmentation.
AVN here has been progressing for a while and the acute history do not match the imaging findings.
