ItemScoliosis in children with cerebral palsy: a population based studyAng, Soon Ghee ( 2015)Introduction Scoliosis is the most common spinal deformity in children with cerebral palsy. Previous published studies have been based on institutionalised patients and not on a total population of individuals with cerebral palsy. Methods This study was based on both prospective and retrospective cross-section analysis of 292 children identified from the Victorian Cerebral Palsy Register. These children were spread across GMFCS levels I–V. The children were assessed during their transition clinic appointment prior to exit from the Royal Children’s Hospital. The research looked at three main sections: clinical review for scoliosis, radiographic assessment of scoliosis, and CHQ and CPCHILD questionnaires survey. Cobb angles were measured by two experienced observers. Results If a Cobb angle of more than 10° was used, then 40% of patients were classified with scoliosis. By changing the definition of scoliosis in cerebral palsy to a Cobb angle greater than 40°, the prevalence of “clinically important scoliosis” was 12.7%. The majority of the severe curves occurred in children at GMFCS levels IV and V. As the GMFCS level increased, the mean Cobb angle increased. The mean score for the questionnaires decreased as the GMFCS level increased. Conclusion The CP scoliosis and the scores for the questionnaire were closely related to the GMFCS levels. The prevalence of CP scoliosis is overestimated in other studies. Our study shows the prevalence of CP scoliosis is 12.7% using a Cobb angle of more than 40°. Non-ambulant children are at high risk of developing scoliosis and formal spine surveillance should be considered.
