Complications and Outcomes of Pedicle Subtraction Osteotomies for Fixed Sagittal Imbalance

Abstract

The clinical result with pedicle subtraction osteotomy is reduced with pseudarthrosis in the thoracic or lumbar spine and subsequent breakdown adjacent to the fusion. For patients with a degenerative sagittal imbalance etiology the results were worse and the complications were higher. Central canal enlargement is critical.
