Purpose This study sought to investigate the shape of spine in students aged 10-13 according to gender and age in order to obtain basic data for early detection and prevention of spine curvature disorders. Methods 10 to 13-year-old primary school students. The pelvic tilt, trunk imbalance, thoracic kyphosis and lumber lordosis were investigated using the Formetric 4D system, which is a device developed to evaluate the spine position. Results More subjects showed normal pelvic tilt, imbalanced trunk towards the left and decreased thoracic kyphosis and lumbar lordosis. The results of this study stressed the importance of regular check-ups to evaluate the spinal position among adolescents who are in their growing period. Conclusion Further studies should be conducted to educate the public about preventing spinal deformity and carry out a primary screening program regularly for the early detection of spinal disorders.
