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

Puntos clave

• To examine the relationship between age at fusion of the ischiopubic synchondrosis and residual acetabular dysplasia after closed reduction for developmental dysplasia of the hip.
• Analyzed patient data from closed reduction of developmental dysplasia of the hip (DDH).
• Assessed ischiopubic synchondrosis fusion age as a predictive factor for outcomes.
• Evaluated IHDI grade and AI measurements before closed reduction.
• Higher IHDI grades and larger AI values before closed reduction are linked to increased residual dysplasia.
• Age at fusion of the ischiopubic synchondrosis serves as a predictor for residual acetabular dysplasia.
• Acetabulum continued to remodel for up to 5 years post-closed reduction.
