In this article, various types of sagittal balance-correction osteotomies are reviewed primarily on the basis of the 3 most commonly used procedures: Smith-Petersen osteotomy, pedicle subtraction osteotomy, and vertebral column resection. Familiarity with the expected imaging appearance and commonly encountered complications seen on postoperative imaging studies following correction osteotomies is crucial for accurate image interpretation.BDBObone-disc-bone osteotomyPSOpedicle subtraction osteotomySPOSmith-Petersen osteotomySVAsagittal vertical axisVCRvertebral column resection ER -
