What this trial studies

This observational study focuses on children with severe, non-ambulant cerebral palsy who are at risk for hip displacement, which can lead to pain and reduced quality of life. It aims to evaluate the effectiveness of various treatment strategies to manage hip instability by following a cohort of 650 patients across 28 sites in 11 countries. The primary outcome measure is the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire, which assesses health-related quality of life. The study will provide insights into the optimal timing and effectiveness of interventions for this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates are children aged 2 to 19 years with severe, non-ambulant cerebral palsy and untreated hip displacement.

Not a fit: Patients under 2 years or over 19 years of age, or those with a Reimer's migration percentage under 30% in both hips, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management of hip instability in children with cerebral palsy, enhancing their quality of life.

How similar studies have performed: Other studies have shown success in evaluating treatment strategies for hip instability in similar populations, but this study's scale and design are unique.
