Patient aged 15 years and 9 months with a right thoracic AIS producing thoracic translocation and listing of the trunk to the right, as well as thoracic flat back producing negative global sagittal balance of the spine and compensatory cervical kyphosis (A,B). The patient underwent posterior scoliosis correction using the AS technique which restored segmental and global coronal/sagittal spinal balance at latest follow-up (age 18 years and 8 months) into adult life (C,D). Clinical photographs demonstrate excellent correction of the coronal deformity and associated rib hump after scoliosis surgery (E–H).
