Abstract
Both Smith-Peterson osteotomy (SPO) and Ponte osteotomy (PO) are the simplest and the most useful posterior-column-only wedge osteotomy technique. The middle column functioning as a pivot point during correction of sagittal imbalance or kyphotic deformity with SPO or PO results in the least change of the length and risk of injury of neural tissue comparing with pedicle subtraction osteotomy and vertebral column resection. Using PO results in closing wedge of posterior column without opening wedge of anterior column like SPO does. Vascular injury due to open wedge of anterior column by SPO is very rare. PO and SPO are the simplest surgical technique of osteotomy and should always be considered to be applied to achieve a balance spine.
