Objective: To investigate the epidemiology of congenital scoliosis (CS) and treatment trends.

Study Design: An age-matched, nationwide, population-based study was conducted using the National Health Insurance and Health Insurance Review and Assessment databases from 2010 to 2015. Data regarding the diagnosis and treatment of scoliosis were extracted using International Classifications of Diseases, 10th revision codes. The age-matched normal population was determined from the Korean Statistical Information Service database. We analyzed the incidence of CS according to age and sex, as well as the proportion of surgically treated patients.

Results: A total of 2338 patients (aged 0-19 years) were diagnosed with CS. The overall average incidence of CS over the 6-year period was 3.6 per 100,000 persons, with the highest and second highest rates at 0 years and 14–16 years of age, respectively. The incidence stratified by age ranged from 1.8 to 20.9 per 100,000 persons among the age-matched normal population and showed a bimodal pattern, with peaks at 0 years of age and the second growth spurt in adolescence (12–16 years for males; 10–14 years for females). Anterior surgery was rarely performed; posterior surgery was performed in 131 patients (5.6% of all patients), with the highest prevalence (60%) in patients diagnosed at 10–14 years of age.

Conclusions: This study is the first Korean epidemiological study on CS and provides information regarding the latest trends in surgical treatment for CS. Only 5.6% of patients underwent surgery within 6 years after the initial diagnosis.
