The Medial Dye Pool Revisited: Correlation Between Arthrography and MRI In Closed Reductions For DDH

摘要

Background: Closed reduction (CR) and spica casting is performed using arthrography to assess the adequacy of reduction based in part on the width of medial dye pool (MDP); however, the amount of MDP that is acceptable and its correlation to the actual anatomic position of the femoral head within the acetabulum has been poorly delineated. The purpose of this study was to determine this correlation and to explore the potential limits of acceptable MDP measurements.
