Study Design: A cross-sectional study.
Objectives: To provide reference data for the study and treatment of thoracic scoliosis.
Summary of Literature Review: There have been no reports on the prevalence of thoracic scoliosis in Korea.
Materials and Methods: From August 2011 to October 2012, radiographs of patients under 80 years of age who underwent routine chest radiographs were retrospectively reviewed. Based on their age when the chest radiographs were obtained, the patients were divided into 8 groups. The prevalence and angle of the curve of thoracic scoliosis were investigated in each age group, and the prevalence of thoracic scoliosis according to sex, the direction of the curve, number of vertebrae in the major curve, the location and rotation of the apical vertebrae, and osteophyte location were examined.
Results: The prevalence of thoracic scoliosis was 2.4% (621 patients), and female patients (3.0%, 375 of 12471) showed a higher prevalence than male patients (1.8%, 246 of 13654) (p<0.001). Right curvature was present in 445 patients and left curvature in 176 patients. In each age group, the prevalence and degree of thoracic scoliosis were 1.1% (14.2°±3.2°), 2.3% (17.4°±7.7°), 2.5% (17.0°±8.9°), 1.9% (15.8°±5.9°), 1.3% (15.5°±6.6°), 2.1% (18.0°±13.6°), 2.9% (14.3°±3.6°), and 6.1% (16.2°±4.8°), respectively. The mean curvature in all scoliosis patients was 16.0°±7.0°. The angle of the curve was significantly different by sex (15.4°±7.1° for males, 16.8°±7.6° for females). The average curve angle of patients with thoracic scoliosis was 16.0°±7.0°, among whom it was 10°?20° in 533 patients, 20°?30° in 64, 30°?40° in 11, and over 40° in 13.
Conclusions: This study could be used as a reference point for the study and treatment of thoracic scoliosis.
