title: [Acetabuloplasty - The Dega and Pemberton technique].
abstract: BACKGROUND
  Hip dysplasia is the most common congenital deformity requiring surgical correction osteotomy in order to prevent early onset of secondary hip arthrosis. The shape of the acetabulum can be modified by Dega or Pemberton osteotomy and is indicated for hip dysplasia and luxation with irregularities of the socket for children aged between 2 and 12 when the y‑physis is still open.
  
  
  METHODS
  We will describe indication, contra-indication, preoperative planning as well as details of the Pemberton technique. In addition, we will provide practical advice based on our long-standing experience.
  
  
  RESULTS
  We present long-term results from the literature and also from our department. In addition, we will explain and critically discuss our own experiences and the risks and complications of surgical techniques. Good long-term results are reported for acetabuloplasties and Salter osteotomy which are preferred for surgical treatment of hip dysplasia in early life. Advantages and disadvantages of both surgical techniques will be compared in the discussion section.
  
  
  CONCLUSIONS
  Dega and Pemberton acetabuloplasty shows good long-term results regarding prevention of a secondary coxarthrosis. However, correct indication is crucial since this surgical technique is more difficult compared to Salter osteotomy but is also associated with a higher correction potential and a lower complication rate.
