title: Advantages of single-stage surgical treatment with salter innominate osteotomy and Pemberton pericapsular osteotomy for developmental dysplasia of both hips.
abstract: OBJECTIVE
  This study retrospectively compared the clinical and radiological outcomes of patients with bilateral developmental dysplasia of the hip who underwent either a single-stage operation (using a Salter innominate osteotomy for one hip and a Pemberton pericapsular osteotomy for  the other hip) or a two-stage procedure comprising consecutive operations.
  
  
  METHODS
  Extensive pre- and postoperative clinical, surgical and radiological examinations were undertaken.
  
  
  RESULTS
  A total of 63 patients received the single-stage operation (group A), and 55 patients received consecutive  operations (group B). There were no significant between-group differences in acetabular index or centre-edge angle correction. Group A had significantly reduced anaesthetic exposure, duration of hospitalization, blood transfusion volume, antibiotic costs and hospitalization costs. Group A  also had a lower rate of surgical complications and avascular necrosis than group B.
  
  
  CONCLUSIONS
  The single-stage surgical procedure was more economical and allowed more rapid recovery than two consecutive operations. The surgical and anaesthesia team must be highly proficient in order to  perform single-stage operations successfully.
