Brief Summary:
Developmental dislocation of the hip is a common disease in children, and its incidence in China is about 9 ‰.The pathological changes of it is complex. The reluxation , subluxation and residual deformity and other complications are relatively common after treatment. The X-ray appears great acetabular index and wide medial gap , small central-edge angle. As there is no effective methods for treating such complications , investigators conducted this trial to find and prove optimal intervention time and treatment programs.

Group/Cohort Intervention/treatment
Pelvic osteotomy Procedure: Pelvic osteotomy

Primary Outcome Measures :
  1. Early treatment can achieve good results in the residual deformity after reduction in developmental dislocation of the hip [ Time Frame: 3 years ]
    Acetabular index of all ages were measured ,and the acetabular index of patients getting early treatment (pelvis osteotomy ) is normal in all ages according to "The measurements of normal acetabular index and Sharp acetabular angle in Chinese hips" publised on Chinese Journal of Orthopaedics in 2010.
