Commentary: Multilevel Pedicle Subtraction Osteotomy for Correction of Severe Rigid Adult Spinal Deformities: A Case Series, Indications, Considerations, and Literature Review

The reviewers applaud the authors1 of “Multilevel Pedicle Subtraction Osteotomy for Correction of Severe Rigid Adult Spinal Deformities: A Case Series, Indications, Considerations, and Literature Review” on a well-done study detailing the clinical utility and outcomes for patients undergoing multilevel pedicle subtraction osteotomies (PSOs) for the treatment of rigid spinal deformity. The authors present 5 unique cases where patients with severe sagittal and coronal imbalance underwent multilevel 3-column PSO for the correction of deformity. Not only do they cover cases of significant thoracolumbar scoliosis, but also they present a case of chin-on-chest deformity requiring a cervical PSO. They also discuss a same-day multilevel PSO as well as a staged multilevel PSO. While this is a small series, it demonstrates the clinical feasibility...
