BACKGROUND Residual acetabular dysplasia is one of the most common complications after treatment for developmental dysplasia of the hip. The acetabular growth response after reduction of a dislocated hip varies. The options are to wait and add a redirectional osteotomy as a secondary procedure at an older age, or to perform a primary acetabuloplasty at the time of the open reduction to stimulat...

In this study, we aimed to evaluate the long-term clinical and radiological results of single-stage open reduction through a medial approach and Pemberton acetabuloplasty in developmental dysplasia of the hip. We treated 32 hips (22 patients) with developmental dysplasia by a single-stage open reduction through Ferguson's medial approach and Pemberton acetabuloplasty. The procedure was performe...
