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

Hongwen Xu2 enrolled

Overview

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. * Parents refused further treatment.

Outcomes

Primary Outcomes

Early treatment can achieve good results in the residual deformity after reduction in developmental dislocation of the hip

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.

Time frame: 3 years
