Prediction of acetabular development after closed reduction by overhead traction in developmental dysplasia of the hip

The AI of 4 years and the CE of 5 years after reduction were the earliest predictors of the final outcome. Careful consideration for the need of acetabuloplasty would be given at 4 or 5 years after reduction by OHT. Bilateral DDH and poor acetabular coverage of the uninvolved hip in unilateral DDH were the prognostic factors of unfavorable acetabular development of the dislocated hip.
