title: [Graf's ultrasound examination method in assessment of dysplasia and congenital dislocation of infant hip].
abstract: OBJECTIVE
  To discuss the application of Graf's sonographic method in assessment of developmental dysplasia and dislocation of infant hip.
  
  
  METHODS
  2258 infants (4516 hips) were examined and evaluated by Graf's method.
  
  
  RESULTS
  The analysis of data showed that type I hip accounted too 78.99%, type II 20.56%, and type III and type IV 0.45%.
  
  
  CONCLUSIONS
  Graf's method can provide qualitative and quantitative evaluation for hips of infants in 3 months after birth. It is an effective in developmental dysplasia of the hip (DDH) and is also useful for early treatment and follow-up of DDH.
