China urgently needs a nationwide scoliosis screening system

Scoliosis is the most common spine deformity and is defined as a radiological lateral Cobb angle of at least 10 degrees (1). Adolescent idiopathic scoliosis (AIS), occurs in individuals aged 10-18 years and disproportionately affects females (2,3). Severe spinal curvature may be related to adverse long-term health outcomes. Early identification and effective intervention could stop or slow the curve progression of mild scoliosis before skeletal maturity. A meta-analysis showed that the pooled prevalence of scoliosis among primary and middle school students in China was 1.02% (95% confidence interval 0.85%-1.18%) (4). There are more than 300 million Chinese adolescents aged 10-18 years, so there could be millions with AIS. Early detection, diagnosis and treatments are urgently needed to improve long-term outcomes.
