A Trial on the Opportunity and Treatment of Residual Deformity After Reduction in Developmental Dislocation of the Hip

A Multi-center Study on the Opportunity and Treatment of Residual Deformity After Reduction in Developmental Dislocation of the Hip

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.

Inclusion Criteria:

• The inclusion criteria consists of patients with large acetabular index ,small central-edge angle after reduction in developmental dislocation of the hip

Exclusion Criteria:

• Age >14 years
• Patients are complicated with mental, neurological disorders (such as hypoxic-ischemic encephalopathy, epilepsy and dementia) or significant barriers to growth.
• Patients are complicated with cerebral palsy, multiple joint contractures disease.
• Children are complicated with dysfunction of liver and kidney , blood disorders, immune deficiency disease and ECG abnormalities.
