title: [Cross reticular bone grass used in slotted acetabular augmentation].
abstract: OBJECTIVE
  To investigate the technique of cross reticular bone grass used in slotted acetabular augmentation ( SAA), and enrich the surgical procedures in the treatment of the DDH.
  
  
  METHODS
  Thirty seven cases were treated with cross reticular bone grass used in SAA, including developmental dysplasia of the hip (DDH) and coaxial plana caused by Legg-Perthes disease.
  
  
  RESULTS
  SAA provided an easy way to shape an adept acetabulum with cancellous bone graft. After the operation a stable hip was obtained. Thirty cases were good, 2 remained limping, 1 had a limitation of abduction of the hip.
  
  
  CONCLUSIONS
  SAA is a safe and effective way to provide an adequate coverage of the femoral head. It is a developed shelf procedure with good stability and for a surgical frame of the hip. SAA method is safe and technically simple.
