title: [Non-operative treatment for severe forms of infantile idiopathic scoliosis].
abstract: BACKGROUND
  Infantile idiopathic scoliosis (IIS) is a rare orthopaedic condition. Braces and casts are popular options in the treatment of IIS but there is a paucity of studies commenting on the outcome of non-operative treatment. The purpose of this study was to analyse failure and success after non-operative treatment for severe forms of IIS.
  
  
  METHODS
  We retrospectively reviewed the data of all children who had been treated for IIS between 2003 and 2009 at a single institution. After calculating the failure and success rates, we additionally performed a risk factor analysis for patients who failed non-operative treatment. Chi (2) and T tests were used for statistical analysis with significance set at p < 0.05.
  
  
  RESULTS
  25 children with an average age of 11 months and an Cobb angle of 46 degrees at presentation were analysed. Seven (28 %) patients were considered as having failed non-operative treatment after an average follow-up of 28 months. The pretreatment Cobb angle was identified as single significant risk factor for failure (55 versus 42) while neither age, gender, nor RVAD seem to influence the outcome. In children who were considered as successfully treated, the Cobb angle decreased from 42 to 18 degrees.
  
  
  CONCLUSIONS
  Non-operative treatment for IIS is successful in 3 out of 4 patients.
