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.

Design outcomes

Primary

Measure	Time frame	Description
Early treatment can achieve good results in the residual deformity after reduction in developmental dislocation of the hip	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.
