MRI risk factors for development of avascular necrosis after closed reduction of developmental dysplasia of the hip: Predictive value of contrast-enhanced MRI
Fig 6
Contrast enhancement of the proximal femoral epiphysis and development of AVN after closed reduction of DDH.
A. Contrast-enhanced axial T1-weighted image of a 7-month-old girl after closed reduction of the left hip shows a global decreased enhancement of the left proximal femoral epiphysis. Note the pulvinar in the left hip joint. B. Follow-up radiograph obtained 1 year after closed reduction shows a small, fragmented secondary ossification center of the proximal femoral epiphysis and widening of the femoral neck suggesting AVN.
