Clinical Trial Summary

Children with cerebral palsy have an increased risk of hip dislocation, which is a painful and severe complication of cerebral palsy. The 20-years evaluation of the Swedish surveillance programme shows that hip dislocation in children with cerebral palsy can be prevented with regular clinical and radiographic examination and early intervention.

We would like to determine the individual risk for hip displacement for Danish children with CP in The Danish Cerebral Palsy Follow-up Program. This could be a valuable clinical tool in deciding on further follow-up and treatment.


Description:

Migration percentage (MP) which is measured from the pelvis radiograph is commonly used to assess lateral displacement of the femoral head and is being used in the Swedish and in the Danish surveillance programme. Most children with an MP > 40 % need surgery to prevent further displacement and prevent dislocation of the hip. In the Swedish surveillance programme they have developed the Cerebral Palsy Follow-Up Programme (CPUP) hip score as a risk score to determine which children are at high or low risk for hip displacement (MP > 40 %) within five years after first radiographic examination.

The aim of this study is to predict the likelihood that a child with cerebral palsy will develop hip displacement (MI> 40) within three years. The design is a prediction study.

Data will be obtained from the national clinical quality database the Danish Cerebral Palsy Follow-up Program and the Danish National Patient Register.

Outcome

Type Measure Description Time frame Safety issue
Primary Development of hip displacement or not measured by the Migration Percentage Migration Percentage (MP) is measured from a pelvis radiograph and is used to assess lateral displacement of the femoral head. A MP < 40 % on either hip is a good outcome, whereas a MP > 40 % on either hip is a worse outcome. Follow-up period of three years.
