Background

Spinal deformities and postural disorders can be assessed by evaluation of trunk surface deformity. Usually, the back shape is assessed. However, the ante-rior trunk can also develop deformity, which is observed by the patient more easily than the back surface. Aim of the study To introduce a new parameter, Anterior Trunk Symme-try Index (ATSI), for anterior trunk deformity assessment. Methods Seventy primary school children, free of idiopathic scolio-sis, both sexes, aged 6-7 years, mean 6.9 ± 0.3 years were examined with digital photography of their trunk, taken from the front in standardized conditions. The anatomi-cal landmarks were: sternal notch, acromions, axill
