Evaluating the alignment and blood flow in the femoral head in patients with congenital hip dysplasia following reduction is essential to the treatment of dysplastic hips. Current practice involves an immediate postoperative contrast enhanced MRI of the casted child to identify hips that may be at risk for avascular necrosis. Contrast enhanced ultrasound (CEUS) is an emerging imaging modality that is feasible to evaluate the perfusion of the cartilaginous proximal femoral epiphysis intraoperatively, after hip reduction and prior to spica casting. This educational exhibit describes the procedure of intraoperative CEUS of the hip from the sonographers’ perspective. Read More

Developmental dysplasia of the hip (DDH) is the leading cause of hip disease in infants. AVN is a potential complication of treatment for DDH, which is traditionally diagnosed on follow-up pelvic radiographs. But classic radiographic findings of AVN may be radiographically-occult for months to years after surgery. To investigate the performance of gadolinium-enhanced magnetic resonance imaging (MRI) for predicting avascular necrosis (AVN) of the femoral head following surgical hip reduction for developmental dysplasia of the hip (DDH) using qualitative and quantitative methods.
