Age at Fusion of Ischiopubic Synchondrosis Is a Predictor for Residual Acetabular Dysplasia After Closed Reduction for Developmental Dysplasia of the Hip

In patients with CR of DDH, higher IHDI grade and larger AI pre-CR were associated with increased RAD. Age at fusion of the ischiopubic synchondrosis is a predictor for RAD. The acetabulum continued to remodel for 5 years after CR, suggesting long-term observation to identify acetabular dysplasia.
